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

Difference:

1. Monochrome printing: not limited to black, suitable for anyone who displays printed text in one color. Multi-color printing can be divided into three categories: color registration, color registration and multi-color printing.

In the method of adding color, another color is added in the range of double lines in monochrome image to make it clear, bright and easy to read. Brush for children's books, mostly used; The method of color registration is that each color is independent and does not overlap with each other, and no other colors are used as boundary lines, which are sequentially overprinted on the printing material. General circuit table, commodity packaging paper, topography printing are often used.

2. Color printing: that is, multi-color printing, which decomposes a natural color manuscript into a primary color separation version according to AdditiveColorMixingProcess, and then reprints the primary color version on the same printing material with SubtractiveColorMixingProcess. Because of the different overlapping areas of primary colors, the natural color printed matter of the manuscript is obtained. All color printed matter, except a few additive methods and register methods, is printed by multi-color method.

Supplement:

According to the nature of their printing business, some printers often classify printing types as book printing, plate printing, packaging printing, trademark printing, parts printing and so on.

Some of them are divided into lead printing (movable type printing), color printing (copper-zinc plate color printing), offset printing, electrostatic printing, screen printing, offset printing (glass printing) and so on.

This distinction has certain limitations.

According to the layout structure of printing plate, printing types can be summarized as relief, lithography, intaglio and filter plate (orifice plate), so now printing is mainly divided into four categories.

But at present, the types of printing are not limited to the above four. Pressureless inkjet printing, electrostatic printing and flexographic printing occupy a certain proportion in the current printing production, especially in the decorative printing system, which will have an increasingly important impact on the design of manuscripts.
