Which Rollers Are Generally Used in The Printing Industry

Common printing methods are mainly the following ways:
(1) offset printing: is an indirect printing method, quality process stability, widely used, such as newspapers books and magazines, packaging and so on.
(2) intaglio printing: the ink contained in the pit of the intaglio plate is directly embossed onto the substrate, commonly used in wine labels, sugar paper and other large quantities of printed matter.
(3) Screen Printing: A printing method using a screen as the plate material, which can be used to print on curved surfaces, and can also be used to produce prints with a wide range of substrates.
(4) inkjet printing: to use inkjet printing machine, inkjet printing machine is a "non-contact with the object" inkjet printing type of high-tech digital printing equipment, can not be restricted by any material.
(5) digital printing: digital printing is a computer file printed directly on paper, different from the traditional printing process of a new printing method. One sheet of printing, no plate making, immediately available, instant error correction, on-demand printing.

Printing Machine Adhesive Roller
Material Composition: Printing press rollers are usually made of rubber, common rubber materials are natural rubber, synthetic rubber and silicone rubber, etc. Different rubber materials are suitable for different applications. Different rubber materials are suitable for different printing needs, such as natural rubber is suitable for ordinary paper printing, while silicone rubber is suitable for special material printing.
Function: It is mainly used for transferring ink and applying pressure. It has a smooth surface and a certain degree of adhesion, which can transfer ink evenly to the printing plate and ensure tight contact between the ink and the printing plate. In addition, the rubber roller is able to generate enough friction between the ink and the printing material by applying appropriate pressure to achieve clear printing results.

Anilox rollers
Material composition: anilox rollers are generally made of metal, such as steel, aluminum, etc.
Function: It is mainly used to adjust the tension of printing material and transfer printing material. Its anilox shape and size can be designed according to the printing requirements to realize different tension adjustment and printing effects. In addition, anilox rollers are able to control the transfer speed of printing materials and printing quality by adjusting its rotation speed and pressure.

Metal Rollers
Material composition: Metal rollers are usually made of copper, aluminum and other materials. These materials have good thermal and electrical conductivity and can transfer heat and electricity quickly.
Function: Metal rollers are mainly used for hot stamping, letterpress printing and other high-temperature and high-pressure printing processes.

Frosted Roller
Material composition: Frosted roller is a kind of printing roller with frosted texture on its surface. It is usually made of steel with different frosted textures processed on the surface.
Function: Frosted rollers are mainly used for printing transparent materials, such as plastic film, glass, etc., which can form a fuzzy transparent effect during the printing process.

Flexible Tube Roller
Material Composition: The hose roller is a soft printing roller. It is usually made of rubber or plastic with good elasticity and softness.
Function: The hose roller is mainly used for printing curved and irregularly shaped items, such as beverage cans and automobile parts.

Grooved Roller
Material Composition: The groove roller is a printing roller with a groove pattern on its surface. It is usually made of metal with grooves of different depths and widths machined on the surface.
Function: Grooved rollers are mainly used for high-precision printing processes such as letterpress printing and offset printing.
