COMMERICAL PRINTING
ROTARTARY PRINTING
DIGITAL PRINTING
Lithography: Etched aluminium plates on a cylinder tranfer ink to an ‘offset’ rubber blanket roller and then to print on surface
Screen Printing: A printmaking technique that uses a woven mesh to support an ink blocking stencil.
Rotogravure: Copper plates (with mirror image) transfer ink dircetly to print surface, usually rolls. Advantage, plates are more durable and so are good for long print runs. Flexography: A postive mirror image rubber polymer plate, on a clinder, transfer ink directly to print surface. Usually roll feed.
Pad Printing: A printing process that can transfer a 2-D image onto a 3-D object Indigo Printing: An Indigo printer is a large CMYK printer. A larger version of a household printer.

COSTINGS. GANG RUN PRINTING Gang run printing saves money as rather than jobs being printed individually. they would probably share a 19�x25� press sheet with other jobs. After 1200 prints they are cut, folded and ograngised to fit into order. With out Gang run printing it would take alot longer and be more expensive.
SAVE TIME, SAVE MONEY Time manegement is very important in the Design for print process. It best to ring the printers as soon as you get the job in. So yo know when your print deadline is.
THE BIGGEST COST OF ALL IS ERROR Proof read everythig, make sure you have spell checked before your job goes to the printers as its going to cost twice as much to re-print.

PRINT FINISHES EMBOSSING & DEBOSSING These are to great design techniques to enhance designs. Embossing creates a rasied image and debossing creates an indented image.
DIE CUTTING The die-citting tool consists of a cutting egde and counter-die. It could have the shape of a straight line- or any complex form. The die cutting operation can be preformed at the same time as creasing.
VARNISHING Varnishing draws attention to the design. Varnishing can be carried out inline (during print) or offline (after printing). There are different types of varishing available: Gloss varnishing, Satin varnishing, UV varnishing, Spot UV varnsih
FOIL BLOCKING Foil blocking has been developed using the letterpress principle. A male block is produced using zinc, magnesium, copper or brass. These are process engraved. The block is heated on press and a metallic or coloured foil is branded on to the material. Foiled logos are incorporated into many corporate identities, used especially on corporate invitations, business cards, letter headings and compliment slips.

PAPER STOCKS Its important for to consider paper stocks for each jobs. The key consideration should be the design and ojective of the project and getting an understand of what stock will work with each project..
COATED PAPER Coated papers are availbe in a gloss, satin, or matt finishes and main objective to a design is to give a fine finish. The out comes are general more sharper and brighter.
UNCOATED PAPER Uncoated paper is much smooth and comes in a much large range of different type, weights and colour. Its much more abosorbent than coated paper. Wove paper: made on a closely woven wire roller, Wove is premium quaility paper with a uniform sureface. Laid paper: is a premium quality paper with a textured pattern of parallel lines similar to hand made paper.
Uncoated
Bond paper: Economic, uncoated wove paper often used for copying.
PAPER WEIGHTS. GSM is the abbreviation for ‘gram per sqare metre’ Paper is graded by its weighed. Standard photocopy paper is about 80 gsm. Where as letter head maybe 120gsm.

CMYK MODELS & GAMUTS RANGE CMYK COLOUR MODEL
CMYK GAMUT RANGE
CMYK also known as ‘four colour process.
A gamut is the range of colour that a device can display or print (in this case) With CMYK you print all the colours with its gamut range.
CMYK is a subtractive colour model for printing. CMYK colors are “subtractive.” This means the colors get darker as you blend them together. Since RGB colors are used for light, not pigments, the colors grow brighter as you blend them or increase their intensity.
All of the colours in the printable portion of the colour spectrum can be achieved by overlapping ‘tints’ of cyan, magenta, yellow and black inks.
Below is a diagram to show RGB and CMYK gamut ranges.
Some of the colors produced by inks cannot be displayed on a monitor, and some colors displayed on a monitor are not reproducible using inks on paper.

COLOUR PANTONE MATCHING SYSTEM (PMS) Pantone Colour matching systems is a largely standardised colour reproduction system. By this standardisation different professions all over the world can refer to the PMS to make sure colours match without direct contact.
SPOT COLOUR Spot colours mean any colour grenerated by a non-standard offset ink such as metalic, flourescent, spot varnish, or custom hand-mixed inks rather than being made by CMYK.
GREYSCALE & MONOCHROME Greyscale is one colour black and all the shade of grey through to white (black and white photography is grey scale). Monoohrome colours are all the colours of a single hue derived from one colout and extended using the shades, tones, and tints of that colour.
HALFTONE This is a mechanical process (as opposed to chemical) for converting tonal values into a series of dots that although solid dots, when printed give the impression of continuous tone.

BEHIND THE LENSE LINEN TESTERS Linen testers are magnifying lense on a stand. They enble you to get a closer look at printed surfaces to see how its been printed. The image below is CMYK becasue you can clearly see the overlaping dots.

PAPER SIZES
COMMERICAL PRINTING SIZE SRA size paper is used by commerical printers. It’s slightly larger than the A series so they provide enough room for grip, trim and bleed. The paper series are untrimmed raw paper. SRA0 - 900 x 1280mm SRA1 - 640 x 900mm SRA2 - 450 x 640mm SRA3 - 320 x 450mm SRA4 - 225 x 320mm
STANDARD PAPER SIZES A0 - 841 x 1189mm A1 - 594 x 841mm A2 - 420 x 594mm A3 - 297 x 420mm A4 - 210 x 297mm A5 - 148 x 210mm A6 - 105 x 148m

PREPARING A PRINT BLEEDS Bleeds are necessary because although modern trimming machines are capable of great precision, they are not perfect. If you create an image that is precisely the same size as the finished piece, and the press sheet shifts 1/64” while being cut, one side of the image will have 1/64” cut away, and the opposite side will have a white “flashline,” 1/64” wide. By creating auxiliary image area that is intended to be cut away and discarded, you can avoid flashlines.
REGITSTRATION MARKS Registration marks are used when printing in mulitple inks to line them up e.g. CMYK
CROP MARKS Crop marks allow the printer to know ehre to cut. The ends of the crop marks should be offset by 1/16-1/8”. In most templates (ours included) crop marks are assigned registration color, rather than black.
PREFLIGHT CHECKS This is the same as what was said in the costings. Its very important to proof read and spell check the work. And make sure all the design are prefect. READY FOR PRINT!
