Drying the ink too fast will reduce the normal transfer performance of the ink and affect the normal progress; it will cause the imprint to be weak, the ink color will fade, the ink drying on the surface of the printing plate and the ink roller, which will hinder the ink during the transfer; make the printing plate graphics and text dry layer Expansion outwards; excessively large amount of desiccant will increase the ink absorption and the blank part will get dirty. The ink drying too slowly can cause overprinting difficulties, adhesion, adhesion, etc., and the firmness will be reduced; it is easy to cause scratches during the conveying process. Therefore, the drying speed of the ink should be appropriate, too fast or too slow is unfavorable.


2. Special structure of printing equipment
Due to the different substrates, the auxiliary mechanism of the tinplate printing press is also different from the paper offset printing press.
