Machines used OFFSET PRINTING MACHINE It is a commonly used printing technique where an inked image is transferred (or “offset”) from a plate to a rubber blanket, then to paper. The offset process is a lithographic process. Lithoghraphy is a process based on the repulsion of oil and water.

PROcess : ■■ ■■ ■■ ■■ ■■

the inking system (ink fountain and ink rollers); the dampening system (water fountain and water rollers); the plate cylinder; the offset cylinder (or blanket cylinder); the impression cylinder.

An image that is offset printed is separated into its fundamental colors. The brochure would be broken down into the primary printing colors; cyan, magenta, yellow and black (CMYK). Thanks to computers this process has become easier. The image is broken down into these four colors and four seperate plates are made.

A plate is made up of areas that are receptive to grease and areas that are receptive to water.

The areas receptive to grease hold onto the ink while the other areas attract water and repel the ink.

These plates are then put on to a press. From the ink fountains, the press pulls in the ink and puts it onto the plate. The press applies great pressure to the plate and the ink imprints the image from the plate onto a rubber blanket. The image is then pressed onto the paper off the blanket to make a print.

All this happens really fast and many impressions can be made from one set of plates. It is a very efficient process and lends itself very well to long runs over a long period of time.

HOT FOIL STAMPING MACHINE In principle, hot foil stamping is the process of using heat and pressure to apply metallic foil or holograms to materials such as light papers, carton board, laminated board, plastics and corrugated board.

The term hot foil stamping encompasses: • Simple flat foil stamping • Deep embossing or embossing combined with foil stamping • Hologram and holographic foil application • Foil stamping combined with micro & structural embossing PROcess : In a hot stamping machine, a die is mounted and heated, with the product to be stamped placed beneath it. A metallized or painted roll-leaf carrier is inserted between the two, and the die presses down through it. The dry paint or foil used is impressed into the surface of the product.

■■ ■■ ■■ ■■ ■■

Die is a metal plate with the reversed image raised from the surfaceTypically these will be made of brass, copper, or magnesium.

Foil is generally manufactured on a film roll made up of pigment, clear mylar, and a heatactivated adhesive.

Substrate is what you want to foil stamp.

WORKING : Foil Stamping comes down to three things: Heat, Pressure, and Time.

The foil film is positioned between the heated metal die and the material receiving the foil.

The die presses the foil onto the material and the heat activates the adhesive.

There are three differing operating principles found among foil stamping machines, commonly called flat-flat, round-flat, and round-round.

COATING MACHINE The roll of substrate, such as: paper, cloth, leather, aluminum foil, plastic film, plastic coated specific function, such as paint or ink, and after drying the winding.

Automatic coating machine works: for screen printing version of automatic coating machine working principle is the same, but its performance under different models and different manufacturers and different. Screen coating machine in a vertical rack has a device to clamp the screen frame.

PROCESS : The coating process consists of applying a coating material to a moving web of flexible sub■■ strate.

■■ The carrier substrate may be paper, film, or aluminum foil and the resulting material’s ■■ additional properties will vary depending on the required application and on the material’s ■■ end-use.

■■ The benefit of coating is that it delivers to the substrate enhanced aesthetic and physical ■■ properties derived from the coating material.

■■ ■■ TYPES : Varnish: to impart a clear, glossy surface to the web ■■ Cold seal: used mainly for products where normal heat sealing cannot be used (chocolate ■■ bars, ice-creams, etc) ■■ PVdC coating: used to improve the barrier properties of transparent films, as well as the ■■ gloss of printed films ■■ ■■

LAMINATION MACHINE Lamination is the technique of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, sound insulation, appearance or other properties from the use of differing materials.

A laminate is a permanently assembled object by heat, pressure, welding, or adhesives TYPES : ■■ Wet lamination: ■■ where the bonding agent is still in a liquid state when the webs are joined together. It is ■■ mainly used to produce a paper-aluminum foil laminate used in flexible packaging.

■■ Dry lamination: ■■ where the bonding agent, dissolved into a liquid (water or a solvent), is applied to one of the ■■ webs, before being evaporated in the drying oven. The adhesive coated web is laminated to ■■ the other under strong pressure and using heated rollers, which improves the bond strength ■■ of the laminate ■■ Wax lamination: ■■ where the bonding agent is a wax or hot melt and is applied in a molten state onto one of the ■■ two substrates. This process allows the production of paper-paper or paper-aluminum foil ■■ laminates that are widely used for the packaging of biscuits and bakery products ■■ Solventless lamination: where the adhesives used do not contain solvents. Solventless adhesive generally indicates a specific type of adhesive composed by two components reacting with each other and consequently not requiring drying.

HYDRAULIC TROLLEY MACHINE A jack is a device that uses force to lift heavy loads. The primary mechanism with which force is applied varies, depending on the specific type of jack, but is typically a screw thread or a hydraulic cylinder.

Jacks can be categorized based on the type of force they employ: mechanical or hydraulic.

Mechanical jacks, such as car jacks and house jacks, lift heavy equipment and are rated based on lifting capacity (for example, the number of tons they can lift). Hydraulic jacks tend to be stronger and can lift heavier loads higher, and include bottle jacks and floor jacks.

WORKING : Hydraulic jacks depend on force generated by pressure. Essentially, if two cylinders (a large and a small one) are connected and force is applied to one cylinder, equal pressure is generated in both cylinders.

However, because one cylinder has a larger area, the force the larger cylinder produces will be higher, although the pressure in the two cylinders will remain the same. Hydraulic jacks depend on this basic principle to lift heavy loads: they use pump plungers to move oil through two cylinders.

The plunger is first drawn back, which opens the suction valve ball within and draws oil into the pump chamber. As the plunger is pushed forward, the oil moves through an external discharge check valve into the cylinder chamber, and the suction valve closes, which results in pressure building within the cylinder.

SCREEN PRINTING MACHINE Screen printing is a printing technique whereby a mesh is used to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil.

One color is printed at a time, so several screens can be used to produce a multicoloured image or design PROCESS : The screen printing process uses a porous mesh stretched tightly over a frame made of wood or metal. Proper tension is essential to accurate color registration. The mesh is made of porous fabric or stainless steel mesh. A stencil is produced on the screen either manually or photochemically. The stencil defines the image to be printed in other printing technologies this would be referred to as the image plate.

TYPES : If the item was printed on a manual or automatic screen press the printed product will be placed on a conveyor belt which carries the item into the drying oven or through the UV curing system. Rotary screen presses feed the material through the drying or curing system automatically. Air drying of certain inks, though rare in the industry, is still sometimes utilized.
