Modern printing mainly includes relief printing, gravure printing, lithography, screen printing, copying, thermal transfer printing, electrostatic copying, inkjet printing and other methods. Among them, screen printing is more special.

Differences:

1. Monochrome printing: not limited to black, any printing that displays printed text in one color. Poly Color Printing is divided into three categories: Casing Method, Register Method and Multi-color Method.

In the color enhancement method, another color is added within the double line range of a single-color image to make it clearer and brighter for easier reading. Generally, children's books are mostly brushed using the overprinting method. Each color is independent and does not overlap each other. There is no other color as the edge line of the range, and it is overprinted on the printed material in sequence. Generally used for printing line drawings, product packaging paper, and terrain, etc.

2. Color printing: that is, multi-color printing, based on the Additive Color Mixing Process, the natural color original is decomposed into primary color separation plates, and then the pigment subtractive color mixing method is used. Color Mixing Process), which reprints the original color plate on the same printed material. Due to the difference in the overlapping area of ??the original colors, a natural color print of the original is obtained. All color prints, except for a very small number of color enhancement and registration methods, are all printed by the compound color method.

Supplement:

Some printing manufacturers often divide printing types according to the nature of their printing business: book printing, plate printing, packaging printing, trademark printing, parts printing, etc.

Some are also classified according to different printing plates or printing equipment: lead printing (i.e. movable type printing), color printing (i.e. copper-zinc plate color printing), offset printing, electrostatic printing, screen printing, collotype Printing (glass printing), etc.

The above distinctions have certain limitations.

The types of printing are divided based on the layout structure of the printing plate, which can be summarized as: letterpress, lithography, intaglio, and filter plate (hole plate). Therefore, printing is now mainly divided into four categories based on this. .

However, it seems that the types of printing are not limited to the above four types, such as: pressure-free inkjet printing, electrostatic printing, varnishing and plastic molding. In current printing production, especially in decorative printing The system clock occupies a certain proportion, which will have an increasingly important impact on the design of the manuscript.
