The principle of sublimation Offset Heat Transfer ink balance is minimizing the amount of wetting liquid in advance of layout is not dirty. Many dynamic variables in the printing process changes are easily lead to ink balance broken. The offset printing machine operator needs to actively check, prevent scrumming. Layout priority detection should be the most easily strumming parts:

a. Small white text and lines turn to be dirty easily, especially when the plate no level. b. The darkened part of the level version is easy to paste off. c. The plate edges are more easily dirty due to their position.

What is said above is mainly aimed at some problems that should be paid attention to the assessment of vision. The qualified factory should check
