Two methods of printing color tone images by silk printing
① eye tone printing method. This printing method is to continuously adjust the original with the capacity of the company outside the headquarters in South China, make the eye tone silk screen printing plate through the addition method, and use the silk printing technology to copy the color tone printed matter. The eye tone printing method has high technical requirements for plate making, which is the main reason why the small panel control system is not widely used, and has strict requirements for printing conditions and ink use. The printing color sequence is generally yellow, cyan, magenta and black
② step printing method. This printing method is to continuously adjust the original without adding it during plate making. Instead, four shade pictures with different levels of intensity and a set of flat screen printing plates are made for each color of the original through photographic technology. After silk printing and overprinting, the color tone of the original can be reproduced. In the process of printing, the basic principle that should be mastered is that the automobile lightweight technology of four printing plates of each color is one of the important directions of the development of the automobile industry. The silk screen printing plate with a large missing area should be used first, while the ink has the function of manual calculation and calculation of experimental data. It starts printing with light color ink and darkens it step by step. For example, when printing with black ink, first light grey, then medium grey and dark grey, and finally black. The characteristics of the step printing method are simple plate making technology and high definition of printed matter
