Analysis of fog printing phenomenon in gravure printing

Reason for imprint version

The technical level of domestic intaglio manufacturers is very different. Due to the current shorter and shorter deadlines for printing, printing companies have very little time for platemaking companies. In the last part of platemaking, the polishing process is easy to neglect. This kind of oversight often brings about the problem of fog printing; in addition, after a long time of printing and wear of metal scrapers, the non-graphics of the printing plate produce shallow dots, so that the fog plate problem occurs. Now.

Reasons for printing film

At present, there are many manufacturers of BOPP film in China, because the differences in the production processes, formulas, and added auxiliaries of various manufacturers are very large, and some films are not flexible enough. In the long-term printing process, the printing plates will wear out resulting in printing plates. Produce shallow outlets, and gradually produce fog issues.

Reasons for the printing environment

The printing environment has a great influence on the quality of intaglio printing products. In particular, it is more noticeable in the seasons where the temperature and humidity are greatly changed and in the bad printing environment (such as very low temperature and low humidity, it is easy to generate electrostatic pollution).

Reasons for ink

Other external causes are easier to solve. It is difficult to solve the problem of fog printing caused by the ink itself. This is a problem faced by the ink industry.
