TYPOGRAPHY
LETTER SPACING
Legibility
The ability to distinguish one letterform from another.
Readability
The ability to understand a piece of type or design.
A collection of characters, letters, numbers, symbols and punctuation which have the same distinct design.
Font
The physical means to create a typeface, be it computer code, lithographic film, metal or woodcut.

Apex
The point formed at the top of a letter, such as the ‘A’, where the left and right strokes meet.
Arm
A horizontal stroke that is open at the end, as seen on the ‘T’, ‘F’ and ‘E’.
Ascender
The part of the letter that extends above the x-height.
Bracket
The curved part of the serif that connects it to the stroke.
Chin
The angled terminal part of the ‘G’.
Counter
The empty space inside the body of a stroke.
Crossbar
A horizontal stroke on the ‘A’ or ‘H’. The crossbar joins to stems together.
Cross Stroke
A cross stroke intersects a singles stem.
Crotch
Where the leg and arm of the ‘K’ and ‘k’ meet.
Descender
The part of the letter that falls below the baseline.
Ear
The right side of the bowl of the ‘g’, also the end of the ‘r’ and ‘f’ .
Hairline
The thinnest stroke in a typeface that has varying widths.
Leg
The lower, downward sloping stroke of the ‘K’, ‘k’ and ‘R’.
Link
The part that joins the two bowls of the double-storey ‘g’.
Loop
The stroke that encloses, or partially closes a counter in a roman.
Serif
The small stroke at the end of a main vertical or horizontal stroke.
Shoulder
The arch formed on the ‘h’ or ‘n’.
Spine
The left-to-right curving stroke in the ‘S’ and ‘s’.
Stem
The main diagonal or vertical stroke of a letter.
Stress
The direction is which a curved stroke changes weight.
Stroke
The diagonal portion of letters such as ‘N’, ‘Y’ and ‘M’.
Leading is a hot-metal printing term that refers to the strips of lead that were inserted between text measures in order to space them correctly. Leading is specified in points and refers to the space between the lines in a block of text.
Track ng s he spac ng o a w o r d Tracking
Tracking refers to the amount of space that exists between letters. This can be adjusted to make characters more or less distinguishable. Reducing the tracking lessens the space between letters, this condenses the text, if the tracking is too tight the letters will crash into one another which can affect legibility.
Kern ng s he space be ween wo e ers
The descending stroke on the ‘Q’.
Terminal
The finish of a stroke.
Vertex
The angle that forms at the bottom of a letter where the left and right stroke meet.
TYPEFACE CLASSIFICATION
Black Block, Blackletter, Gothic, Old English, Black or Broken typefaces are based on the ornate writing style prevalent during the middle ages. They tend to be difficult to read in large text blocks and seem antiquated.
ROMAN Roman type has proportionatly spaced letters and serifs, it was derived from Roman inscriptions. It is the most readable type and is commonly used for body text.
GOTHIC
Gothic, sans serif or lineale typefaces do not have the decorative touches that typify Roman typefaces. Their clean and simple design makes them ideal for display text, but make them more difficult to read in long passages.
SCRIPT Roman type has proportionatly spaced letters and serifs, it was derived from Roman inscriptions. It is the most readable type and is commonly used for body text.
TYPEFACE STYLES A typeface family contains the range character styles and weights which can be applied to the same basic typeface. The typeface I have used for examples below is Helvetica Neue.
ROMAN Originates from inscriptions found on Roman monuments.
ITALIC A version of the Roman cut that slopes to the right. Most typefaces have an italic version.
MEDIUM A middle weight between the Roman and Bold.
BOLD Uses a wider stroke than Roman and is also called black, super and poster.
L GHT A variation of the Roman cut with a lighter stroke.
CONDENSED A narrower version of the Roman cut.
ABSOLUTE MEASUREMENTS Absolute measurements are measurements of fixed values. A millimetre is a precise measurement. Points and pica, the basic typographic measurements have fixed values. Absolute measurements are shown in finite terms and cannot be altered.
The Point System
The system was developed in the 19th century by Pierre Fournier and Francis Didot. The modern point is 1/72 of an inch.
10 po nt type. Type Point Size
The point size of a typeface is measured from the ascent line (highest ascender) to the descent line (lowest descender). The point system was created for metal type. Metal type blocks leave space at the top and bottom to allow space, the point size is a measure of the block, not the letter.
RELATIVE MEASUREMENTS In typography many measurements such as character spacing are linked to type size. Ems and Ens are relative measurements that have no prescribed absolute size. Their size is relative to the size of type that is being set.
Em
An em is a unit of measurement derived from the width of a of the cast upper case ‘M’. The em equals the size of a given type (the em of 60 point type is 60 point, the em of 12 point is 12 points). It is used to accurately space paragraph indents.
En
An en is a unit of measurement equal to hald of one em. It can be used to mean ‘to’ in phrases such as chapters 10–11 An en rule is also used to mean ‘and’.
Hyphen
A hyphen is typically one-third the length of an em. It is used to separate parts of compound words, to link the words of a phrase in adjectival hyphenation and to connect the sylabbles of a word that is split across two lines.
X-Height
The ‘x-heght’ is a term applied to the distance between the baseline and the mean line of non-ascending or lower case letters. The letter ‘x’ is used as a gauge because it is flat at both the top and bottom. The X-height is a relative measure specific to the typeface in question.
Va ue w
The grid is used as a way to consistently organise elements on a page. There are two common types of grid, module based and column based.
Columns
A column is an area into which text is flowed so that it is presented in an organised manner.
Kerning
Kerning is the space between two letters. Certain letter combinations have too much or too little space between them, this can make some words difficult to read.
Two Rules of Kerning One

Greyscale
w
A greyscale is a tonal scale or series of achromatic tones that have varying levels of white and black to give a full range of greys. A greyscale is used to reproduce contious tone photographs. It does this by converting colours into the most approximate levels of grey. Up to 256 shades. The intensities of these greys are reproduced on the printing plate throught he use of a half-one screen.

The mould of polystyrene is a three part process. In the first part tiny spherical EPS beads are expanded up to forty times their original size. In the second stage the boards are stored in huge canvas silos and are left to absorb air for 24 to 48 hours. In stage three the freshly expanded beads are poured into manufactured moulds where steam and pressure are applied, softening the beads and compressing them so that they bond together into the required shape and density.

A black variant of EPS exists that is used in thermoinsulation. The colour comes from introducing carbon flakes into the beads to enhance its thermal performance. This is an more aesthetically pleasing variant of the standardised white EPS. Sheet polystyrene is moulded in large locks that are cut using hot wiring cutting machines. The cell structure of this material means that in appearance the material seems quite smooth but printing will achieve mixed results.

PRINT FINISHING
Cutting and Trimming
As most commercial printing jobs use paper that is slightly larger than the finished design will be, there will need to be cutting and trimming to achieve the final desired format.
Cyan and Bak %
%
FLEXOGRAPHY
Trim lines are identified by crop marks, these marks are also used to help with registration of the printed page. Trimming is paid for in the printing of a design, so no extra charge is incurred. This is different to other finishing techniques, such as folding, which cost extra.
Drilling and Punching
Designs that are ring or post bound require holes ranging between 1/8 inch and 1/4 inch. Commercial printers use a drill to make these holes according to size and placement specifications. Spiral and plastics comb binding require puching holes, a process that costs a bit more than drilling.
Perforating
Peforating involves punching a line of holes to make tearing easier. It can be done as part of the binding process to make signatures easier to fold before they are bound and trimmed. Peforation is used as a means to facilitate tear-offs on designs that require a response, such as business reply cards.
Scoring
To make folding more efficient a crease is applied using a metal rule or a wheel so that an embossed ridge is formed on the substrate. Heavy substrates that are to be folded should always be scored. Scoring is also important to avoid cracked ink on fold lines when using coated stocks with heavy ink coverage. Flexography (often abbreviated to flexo) is a form of printing process which utilises a flexible relief plate. It is essentially a modern version of letterpress which can be used for printing on almost any type of substrate, including plastic, metallic films, cellophane, and paper. It is widely used for printing on the non-porous substrates required for various types of food packaging (it is also well suited for printing large areas of solid colour).
FOLDING METHODS Folding is used for almost all multi-page print jobs in some form or another.
Mountain
One of the two basic folds that are the basis of all the other folds. In a mountain fold, you fold the paper towards yourself.
Advantages
The relief printing plate is suitable for printing on non-porous surfaces, such as metal. It is used to print drink cans, plastic bags and much more.
Valley
The second of the two basic folds that are the basis of all the other folds. In a valley fold, you fold the paper away from yourself.
Disadvantages
Large print runs are required using this process.
OFFSET-LITHOGRAPHY
Gatefold
A gatefold has extra panels that fold in to the central spine of the publication with parallel folds so that they meet in the middle of the page. The extended pages are folded and cut shorter that the standard publication pages so they can nest correctly.
Throw-outs/ Throw-ups
w
A printing process where an inked image from a printing plate is transfered or offset on to a rubber blanket roller, which is then pressed against the substrate. Litho uses a smooth printing plate and works on the basis that oil and water will repel each other. When the plate passes under the ink roller, non image areas that have a water film repel the oily inks that stick to the image area. Litho produces good photographic reproduction and fine linework on a veriety of stocks. The printing plates are easy to prepare and high speeds are available,. These reasons make it a cost effective way to print. Offset litho is available in sheet and roll fed form. Sheet fed is more appropriate for smaller print runs such as flyers, brochures and magazines while web printing is more appropriate for higher run jobs like newspapers, magazines and reports.
Advantages
Uses an engraved printing plate. Can print on a wide variety of substrates. One of the most cost-effective and commin methods in commercial print today.
One colour and does not reflect paper stock or true colour. Proof has a blue colour and the image fades with time.
121 A8 74mm x 52mm
210 A9 52mm x 37mm
A proof of an individual photo or group of photos not included as part of the individual page layout.
Advantages
For checking colour before the final proof. Many photos can be proofed at once to save time and materials.
Disadvantages
Images not seen in the layout.
Tip-in
A tip-in is a means to attach an insert into a book or magazine by gluing along the binding edge.
Concertina
Each fold runs opposite to the previous one to obtain a pleated result. The outer panel needs to be bigger than the inner panels, this hides the rough folding edges of the final piece.
Back/Front Folder
Wings either side of the central panel have a double parallel fold so that they can fold around and cover both sides of the central panel.
Double Gatefold
Reasonably high start-up costs for low print-run jobs. The plates can wear out quickly compared to other print processes.
The double gatefold has three panels that fold in towards the centre of the publication.
PAD PRINTING
Duelling Z-Fold Z-Fold wings fold in to the centre panel and meet in the middle.
Front/Back Accordion
Pad printing is a printing process that can transfer a 2-D image onto a 3-D object. This is accomplished using an indirect offset (gravure) printing process that involves an image being transferred from the cliché via a silicone pad onto a substrate. Pad printing is used for printing on otherwise impossible products in many industries including medical, automotive, promotional, apparel, and electronic objects, as well as appliances, sports equipment and toys. It can also be used to deposit functional materials such as conductive inks, adhesives, dyes and lubricants. Physical changes within the ink film both on the cliché and on the pad allow it to leave the etched image area in favor of adhering to the pad, and to subsequently release from the pad in favor of adhering to the substrate. The unique properties of the silicone pad enable it to pick the image up from a flat plane and transfer it to a variety of surfaces, such as flat, cylindrical, spherical, compound angles, textures, concave, or convex surfaces.
Three parallel folds, the two panel outer wings fold in to and out of the centre. The double panel centre serves as the cover.
Front/Back Gatefold
The same as a normal gatefold, but with an extra panel inside the front or back.
Half Cover from Behind
An accordion fold where the penultimate panels forms a back cover that the other panels fold in to to create a book. The other half size panel folds around the book from behind to cover the front with the first half size panel.
Harmonica Self-Cover Folder
An accordion fold where the first two panels form a cover that the other panels fold into. The first two panels need to be larger than the others to allow for creep.
Mock Book Fold
Advantages
The ability to print on 3 dimensional substrates, golf balls, tv controls, keypads and more.
Disadvantages High start-up costs.
ROTOGRAVURE
Essentially an accordion fold, where the penultimate two panels form a cover that the other panels then fold in to to create a book.
Advantages
Long lasting printing plates. Good image reproduction. Low cost per unit if using very high print runs.
Disadvantages
High start-up costs. Slightly pixelated lines and text. Very high print-runs are needed to make it profitable.
SCREEN PRINTING
The screen is placed on top of the substrate to be printed, a squeegee or rubber blade is used to press the ink through the stencil and on to the substrate. The screen can be used many times.The screen printing process has an immediacy that other print processes don’t.
Tape
A cloth tape is treated with heatsenstive glue is wrapped around the assembled covers and pages. Heat is applied, causing the glue to adhere to the pages and cover. Tape bound books lie flat.
SPECIAL FINISHES Special finishes can range from diecuts to varnishes.
Die-Cut
A process that uses a steel die to cut away a section of a page. Die-cuts have many uses and are mainly used for decorative purposes to enhance the visual performance of a design. They may also serve a physical function, such as making unusual shapes or creating apertures that allow users to see inside a publication. Die-cuts produce a range of effects from the striking to the subtle.
Die-Stamp
The traditional way to emboss, using an engraving plate or die. The die is pressed into contact with the paper. Inks used in die-stamping have traditionally been oil based and slow drying. A die can be used without ink, this procedure is called blind embossing. Die stamping, like thermography offers an alternative to more conventional print processes, creating a tactile and luxurious finish.
Dip Moulding
Dip moulding lends itself to low-volume production runs and the development of projects. It is versatile enough to cope with high volume production when needed. It has cheaper tooling costs for both prototypes and production tooling. The preferred material for tooling is aluminium, with more complex shapes being made with a wooden pattern then cast in aluminium. The dip-moulding process does not lend itself to forming text out of the tooling as it is difficult to strip the finished mould without damaging the finished product. The surface can be printed, with silk-screen offering the greatest flexibility. Pad printing can be employed for more complex, 3 dimensional surfaces. The process offers a very specific finish and feel. Given it’s synthetic and tactile nature.ing a tactile and luxurious finish.
Embossing and Debossing
Paper is pressed between two moulds called dies. The moulding of paper between the dies results in a raised impression. If an impression is moulded so that it is lower than the paper’s surface it is called a deboss. Embossing can be combined with a printed image or foil stamping to enhance the three-dimensional appearance of an image. An embossed impression made independend of a printed or foil-stamped image is called a blind emboss. Soft, uncoated papers generally take a better embossed impression than hard or smooth coated papers.
Foil Blocking
Foil blocking operates as an addition to other printing methods, allowing metallic finishes to be applied to a surface. There is a huge range of foils including metallic, colour and clear and some holographic or decorative foils. There are strict rules to follow for foil block, this should ne be ignored. You cannot foil on top of foil; if you apply foil on the reverse side, the foil on the front will be removed. Foil blocking can be used on stationary and letterheads. A potential is that the foil reheats and peels away from the paper depending on the printer used. If planning to use this method for such purposes, it is important to check compatability with all office printers on-site beforehand. Foiling can sometimes be considered an overdecorative process.
HF Welding
HF (or high-frequency) welding is also known as RF (radio-frequency) welding or dielectric sealing. The principle behind the process is the use of high-frequency radio energy to produce a molecular agitation in the materials being processed to the point that they melt and weld together, typically forming a bond as strong as the original material. This approach could be considered as a packaging alternative, although 3D constructions do tend to stretch the capabilities of this process.
Injection Moulding
Used to make items such as shampoo bottle tops and CD cases.This process is a great deal more expensive than processes like thermoforming. As a process it can be sourced and used internationally and nationally. The outcomes are well worth the extra expense associated with the process.
Kiss-Cut
A method of die-cutting whereby the face material of a self-adhesive substrate is die cut but not all the way through to the backing sheet. This enables the face material to be easily removed from the backing sheet.
Laminates
Lamination provides the best protection of all methods. Lamination creates an exceptionally strong surface that repels moisture, this means the design can be washed wthout being damaged. The process involves applying a layer of polyester, polypropylene or nylon film to one or both sides of a printed sheet. Laminates are available in dull and glossy finishes.
Nylon Laminates
Nylon laminates are the most durable and expensive type of laminate available. Nylon laminates are recommended for lightweight substrates such as paperback covers and designs where metallic inks are involved.
Polyester Laminates
Polyester laminates have are hard surface and are reasonably priced makes polyester laminates appropriate for case-bound books and for designs where durability and longevity are important.
Polypropylene Laminates
Laminates made of this material are often used on dust jackets and packaging. They are more likely to be scratched and scuffed, polypropylene laminates are the least expensive. Polypropylene laminates can also be applied to lightweight substrates and surfaces printed with metallic inks with-out the risk of paper curling.
Rigid Box Making
Thermoforming
When a planning a publication, the capacity of a cover to contain its pages. The dimensions of the spine will vary depending upon the number of pages in the publication.
Bellyband
A plastic or paper substrate that wraps around the ‘belly’ of a publication.
Case
The pages form signatures that are sewn using thread and then glued to linen tape for flexibility and strength. Case-bound books lie flat and are extremely durable.
The cover and pages are sewn together with thread and then tied off. The knot and ends remain visible. This is a process done by hand and is typically used for publications with 36 pages or fewer. Pamphlets lie flat.
The screen is made of a piece of porous and finely woven fabric stretched over a rectangular frame. Areas of the screen are blocked off allowing a stencil of the image to be printed through.
Stab is also referred to as Japanese binding. Sheets are sewn together so that the thread is visible on the spine and sides of the book.
Capacity
Pamphlet stitch
Screen printing offers a lot of versatility for the designer. It gives scope to experiment with a lot of different inks and materials. Screen printing can be an automated process, or hand done.
Stab
Binding is needed for multiple page documents. There is a wide variety of binding techiniques, ranging from simple to elaborate solutions.
BINDING TECHNIQUES
Rotogravure (Roto or Gravure for short) is a type of intaglio printing process; that is, it involves engraving the image onto an image carrier. In gravure printing, the image is engraved onto a cylinder because, like offset printing and flexography, it uses a rotary printing press. Once a staple of newspaper photo features, the rotogravure process is still used for commercial printing of magazines, postcards, and corrugated (cardboard) product packaging.
Hole are punched through the pages with a machine, and then a wire coil is spun up the spine of the book. Spiral bound books lie flat.
Among the most luxurious and desirable forms of packaging. The boxes are often handmade. Versions of this packaging can be made by machine but the choice of material and construction is more limited. A rigid box consitst of a hard base material, which is cut to shape, fixed together to form a box and covered in cloth, paper or vinyl. The box can be lined, usually using a coloured, uncoated paper. Larger boxes are more difficult to cover and therefore more expensive. It is very difficult to make a rigid box any shallower than 15 to 25mm, for these cases it is better to use a cardboard carton.
Triple Parallel
Parallel folds that create a section that nests within the cover panels, with a front opening. This type of fold is commonly used with maps.
A contact print produced from film. Shows imposition, photos and text as will appear when printed, together with trim and binding edges.
Rapid as no processing is involved and pages can be folded, trimmed and stitched to approximate the finished job.
Throw-ups and throw-outs are sheets of paper folded into a publication. They allow for larger scale images than can be used in the original design size.
Disadvantages
Blueline, Dylux or Salf Proof
Scatter Proof %

The digital file need to be available, unlike other print methods which can be produced from a physical plate.
Spiral
Limited image reproduction quality. Very expensive if being used for small print runs.
Finishing techniques are applied to a job after it has been printed. They create special effects which cannot be achieved with ink.
Digital printing refers to methods of printing from a digital based image directly to a variety of media. It usually refers to professional printing where small run jobs from desktop publishing and other digital sources are printed using large format and/or high volume laser or inkjet printers. Digital printing has a higher cost per page than more traditional offset printing methods but this price is usually offset by the cost saving in avoiding all the technical steps in between needed to make printing plates.
Pages and covers are stapled through from front to back. As the binding runs on the edge of the book. This means that a lot of space is lost on the inner margins. Side stitched books do not lie flat.
Very high print runs can be achieved using this process, for a relatively low cost. Typically used for newspaper printing.
There are seven basic printing methods that are used to produce most of the printed material you see around you in the world today.

Scented inks can be supplied in a wide selection of smells and can also be synthesised to use a specific fragrance. As scented inks are water based they can only be printed on unsealed paper (paper not plastics). On other surfaces water-based ink does not adhere to it and will scratch off. The scent has will usually lose potency over time.

Normally used on scratch cards or other promotional items, rubremovable ink is latex based. It is supplied as a metallic, as it’s function it to obliterate what it overprints. The ink is quite fragile and difficult to work with, but it can be effective when printed in solid areas. It gives a rubberised feel and communicates that the area should be handled with care.

These inks are supplied in a limited range of colours. Black is the preferred colour as it creates dramatic results. Heat sensitive inks are suspended in a semi-clear base and works best when screen printed. The reactive temperature can be varied according to climactic conditions. As with scented inks, the system is water based and is supplied for printing on paper based substrates. It can be used on plastics but a number of layers of varnished will need to be applied for it to key in. This is time consuming and not very cost-effective. Heat-sensitive ink also has a tendency to scuff if not properly sealed.

Side stitch
Web printing prints from a roll of paper rather than separate sheets. This allows for higher printing volume and speed with a lower production cost. Web can be used with litho but most commonly with relief printing methods such a rotogravure and flexography as the plates are more durable. Due to the scale and cost of this production method, it is not suitable for low volume printing.
Contract Proof
The cover and pages are folded and stapled. As the entire book is folded in half there is a maximum thickness of roughly half an inch for effective saddle stitch binding. Saddle stitched books lie flat and are a low cost binding technique.
Covers and pages are drilled and bound with a threaded post and screw. The cover then turns on itself to hide the fastening. Pages can added and subtracted. Books have to be hand assembled, screw and post bound books do not lie flat.
Disadvantages
Costly as the plates have to be set up, particularly if another proof is required following changes.

The 4-colour printing process can produce a wide range of colours, however it is sometimes desirable to use a special process (spot) colour. The are specially made inks. A special colour is solid colour, rather than made a CMYK colour which is created by using a series of dots. As a result the colour is much more vibrant than CMYK mixed colours. Special colours are also used to produce metallic and flourescent colours. When using special colours an extra plate needs to be used in the production process. This means extra cost to a project. Such things must be taken into account when considering the use of special colours.

There is also a range of holographic boards utilizing metalised polyester film that carriers a micro-embossed holographic pattern. There is no choice beyond those patterns already available. Despite their highly reflective and smooth surfaces, these materials can still be printed conventionally. With lithographic printing, inks must be selected that dry on non-absorbent substrates. UV curable inks are also preferred. Caution needs to be exercised when handling more reflective boards as they have a tendency to scratch and mark. This laminated surface is soft, with any minor blemish being obvious because of the reflective quality of the material. Inks must be selected that will dry on nonabsorbent surfaces. Certain inks needs to cure for up to 48 hours, or they will scratch.

Aluminium is a lightweigh popular substrate for binders. Its edges do need to be sealed or anodized by immersing the material in an anodizing solution and running an electric current through it, otherwise it is prone to oxidisation and marking from fingers. There are not many suppliers or manufacturers who can produce high quality finished goods from metal.

The use of leather in a project generally denotes wealth, tradition and luxury. Leather can be screen printed, embossed and foil blocked. It should be noted that, as leather is animal skin the surface and texture of leather is a variable which could hamper the application of a design. Care should be taken when glueing as leather has a tendency to contract when mounted or bonded. More rigid leather will die-cut and trim far better than softer pig-skin or goat-skin leather. If cost is an issue there are a number of synthetic materials that mimic the grain of leather, and some have even been developed to smell like it too.
Metal could be regarded as a material that has very limited applications with the design process. It has a look, feel and density that will rarely be appropriate.Cost is an important factor when considering using metal for a project. A reason for this is the extra processes that metal has to go through prior to being ready to work with. The materials most commonly used by designers are aluminium and stainless steel, both of which are easily cut, creased and screen printed. Stainless steel is much harder than aluminium and can be supplied in very thin gauges. The thinner the gauge the sharper the edges become. Stainless steel is good for having designs etched in to or through it’s surface.

There is an almost infinite choice of leather to use. It is an expensive material to use, and decisions based on expectation of how leather should feel and smell will lead you to higher-priced skins. Leather is mainly available at specialist merchants who normally supply skins to make handbags and belts and therefore are structured towards this market.

High density foam has a 3-stage production process, commencing with polymer being blended in line and extruded into solid sheet or slab form. This sheet is then cross-linked to create a lattice-like structure at a molecular level within the material. This allows the material to be thermal moulded, as crosslinked foams can be stretched and compressed, and retain their shape when cooled.

Felt
The largest palette tends to be supplied to a thickness of 1mm. It is rare to find thicker felt in colours other than black. This is partly because you cannot dye the felt consistently. A more limited palette of colours, but one with a far more interesting texture is provided by ‘industrial’ felts. Usually supplied in off-white, grey and brown, this industrail felt is used to polish and finish jewellery and metalwork and can be found encasing the strikers of church bells. Industrial felt could be seen as having a texture and finish aligned to materials such as grey board and corrugated cardboard.

Corrugated cardboard consists of flat outer sheets sandwiching a central core or filling of corrugated fluted paper (called a medium) that resists crushing under compression. When used in a box this gives cushioning to the boxes contents. The liner and medium are glued together along the outsides of the peaks and valleys of each flute, boxes are usually designed with the flutes running vertically for stacking strength.
Felt is made from wool matted together into fabric by beating, rolling, suction and pressure. The most common wool used in felt manufacture is sheep wool. Some felts can be dyed in a veriety of colours. Felt is available direct from the manufacturer, brighter colours tend to be available at handicraft markets.

Cork is the bark of the cork tree. Cork is extremely bouyant as more than 50% of the structure is air, yet it remains solid. This makes cork very compressible without breaking, making it flexible and resilient. As the surface is naturally uneven finish can be problematic,particularly when attempting to print fine text or complex logos. Cork can be die-cut and guillotines with relative ease.

It is more common to find paperbacked or tissue-lined book cloths on the market. These differ from cotton book cloths on the market. These differ from cotton book cloth as their material is predominantly from a synthetic source, such as rayon. Cotton book cloth has the disadvantage that adhesive will penetrate the cloth when glued. Rayon has a flexible backing or lining that prevents this, and is cheaper than cotton. A further disadvantage is the availability of much brighter colours and more variances of weave. Cotton book cloth tends to be associated with dry legal or medical tomes, whereas as rayon with art or design based projects. Cotton cloth is more durable than rayon.

A raster image is any that is composed of pixels within a grid, each pixel contains colour information for the reproduction of the image. Rasters have a fixed resolution, which means that an enlargement of the image results in a quality decrease.

Woven cotton that is coated in a starch and pigment mixture then subjected to live steam before being spread across the cloth. The granules of starch burst open and thicken , causing the material to thicken, giving the starched effect. Drying is usually done by a steam heated drum, cloth is wrapped around it during its journey through the spreading machine. The heat dries the starch the starch on to the cloth. When the material is glued, the process is reversed as water in the glue softens the starch granules, making the material pliable and easy to wrok with. The starch prevents the glue from penetrating through the cloth.

Perfect
Loose pages are adhered with glue along their bound edge. The cover is then wrapped around and glued. Perfect bound books do not lie flat.
Plastic comb
Probably the least aesthetically pleasing binding method of them all. The plastic comb looks cheap and the books do not lie flat.
A method used in processing plasticbased substrates. The material is heated to its thermoforming temperature and then immediatly shaped. Pressure is maintained on the material until it has cooled. The tooling used in this process is cheaper than that used in injection moulding. The tooling is is generally made from aluminium. As the process is generally used for industrial applications it tends to be ignored for more aesthetic reasons. Thermoforming is a very precise process, the material has to be consistent and the sheet must be heated evenly to the correct processing temperature. The initial costs of this process can make it prohibitive. The process does offer alternative possibilites to a project.
Thermography
Thermography or relief printing, is used to raise a design off the paper and adds another dimension to the design. A potential problem with thermographic printing is thermographic ink can melt if put through the same temperature twice (i.e laser printing, as could be used with a letterhead paper).
Varnishes and Coatings
The three main types of varnishes and coatings that are used are;
Spot Varnish
A clear coating is applied on press or in line. Spot varnishes cost the same as applying an extra ink would cost. Spot varnishes come in glossy or dull finishes and can be lightly tinted with other inks. Spot gloss varnishes are usually used to enhance photographs and other types of image by giving them a high sheen and richness. Dull varnishes are often applied to areas of text on a glossy, coated paper to prevent glare. Spot varnishes offer little protection against scuffing.
Aqueous Coating
A gloss coating made from a mix of polymers and water that is often applied to magazine and brochure covers as a means of protection against scuffing, dirt and water. Aqueous coatings are applied as a flood varnish, meaning the entire
page is covered. Aqueous coatings require a special coating unit and cost roughly twice as much as spot varnishes.
UV Coating
A UV light-cured process that involves a platic liquid, ultraviolet coating offers more protection and a higher degree of gloss that aqueous coating. Some printers apply UV coating in the press line but often it is supplied separate from the printing process.
COMMERCIAL COSTINGS Everything discussed in this book up to now costs a price. If you want to add finishes such as folding, binding or specials to a job it will increase the cost. If you want your design printed on A2, rather than A4 paper it will cost extra. This section of the book will discuss basic costing considerations when deciding the print and finishes your design requires.
PRICING A PRINT JOB The six key areas that will affect the overall cost of a printed job are; format, colours, quantity, material, printing method and finishes.
Format
The final size of the printed document will affect the price of a print run. Most commercial print on B1 or B2 sheets or use a roll, such as web-offset, the larger the format of the final design the more press sheets will be needed to print the job, thus increasing costs.
Colours
In most commercial printing processes colours are added in separate layers. As this is the case the more colours used in a design will increase the number of plates that need preparing and inks being used. This will increase the cost. Where special (spot) colours are being used an extra plate is needed, this increases the cost even further. For this reason it is important that colour usage is managed closely.
Quantity
The quantity of a print-run, will affect the cost of a print run in a similar way the format will. The higher a print run, the more press sheets are needed, this increases the cost.
Material
The material a design is printed on will affect the cost. For example, it will cost more to print on gold than paper. The material used will affect the drying time of the ink, this again, will increase the cost of the print job. These are things that need to be considered before sending a job to print.
Printing Method
Choosing between offset-lithography, digital, roto and other printing methods can greatly affect the price of a print job. Some methods are best used for high print runs (roto) and other for small (digital). The printing method is one of the most important things to consider.
Finishes
From binding, folding and specials when finishes are used the cost of a printing job will increase.
