The Most Detailed UV Flated Inkjet Printer Principle

Post by lasercutting »

Lithographic printing was developed and named after an early lithographic printing. The early lithographic printing was applied after the plate was polished and then modified to a metal zinc plate or aluminum plate. But the principle was unchanged.

From the core value of graphic advertising design training, there is no difference between the printed and non-printed parts, that is, flat. The water-oil blending principle maintains a layer of oily film on the printed part, while the non-printed part can absorb the appropriate water. Assuming that after the oil ink on the plate, the printed part will repel moisture and absorb the ink, and the non-printed part will absorb moisture to form the anti-ink effect. This method is called "lithography".

What is the lithography method?
The lithographic printing method is developed from the early lithographic printing transfer method, and the drawing on the transfer paper falls on the plate and becomes anti-textured and then printed on the paper with a right pattern.
Due to the pressure exerted by this method during printing, the lithographic plate is originally a flat plate (that is both the printed and non-printed portions are flat). After the pressure is applied on the plate, the ink that occupies on the plate is diffused and expanded, resulting in poor line drawing. Therefore, it was later improved to be the Offset Printing method. The printing method was to make the layout into a right pattern. When printing, it was transferred to the rubber tube as a reverse pattern, and then the anti-pattern printing was applied to the paper which can improve the elasticity of printing pressure.

The early lithographic printing was lithographic flat type, and later it was developed into two types: flat round press type and round round press type. Lithographic round press machines are mostly used in special printing, such as draft machines for proofreading. As for machines used to print paper, they have all been improved to round round press type. The flat plate round type is also the flat layout of the printed page, and the pressure part is the roller type cylinder, which is similar to the flat plate press machine in the convex plate. Round-circular press type refers to the printing plate wrapped on the drum, the other drum on the machine is called the rubber drum, and the pressure part is the roller type drum. The constructed machine of three basic rollers is called "Offset Printing Machine".

What are the advantages and disadvantages of lithography?

The advantage: the plate making work is simple and the cost is low. The color plate is accurate and the printing plate is easy to copy. The print is soft. It can bear large quantities of printing.
Shortcoming: Due to the effect of water glue during printing, the tonal reproduction is reduced, and the vividness is lacking. The layout ink is thin. Special printing applications are limited.
What is the application range of lithography?Posters, profiles, brochures, newspapers, packaging, books, magazines, calendars, other related color prints and large numbers of prints.
