1 Mesh transfer printing method. This kind of printing method is to use continuous adjustment of the original, through the screen method to create a screen transfer screen printing plate, using screen printing technology to reproduce color tone prints. The screen printing method has relatively high technical requirements and is technically strong. It also imposes strict requirements on printing conditions and ink usage. Printing color sequence is generally yellow, cyan, magenta, and black.
2 step printing method. This kind of printing method uses continuous adjustment of originals. When the plate is made, no screen is added. Instead, four shades of shades of shades and a set of flat screen plates are produced for each color of the manuscript. Print overprinting can reproduce the original color tone. In the printing process, the basic principle that should be mastered is that the four printing plates of each color should be printed with a large screen printing plate, and the ink is first printed with a light color ink and gradually darkened. For example, when printing with black ink, first light gray, then gray and dark gray, and finally black. The characteristics of the hierarchical printing method are: the technology of plate making is simple and the clarity of the printed matter is high.
