About the causes and solutions of knife line in the process of gravure printing

Gravure printing often has many quality failures, of which the generation of knife line is one of the most common failures, the generation of knife line to scrap the product, resulting in economic losses. In this paper, from a professional point of view, combined with the actual production experience, the five major factors affecting its production are analyzed and summarized in detail, and the corresponding solutions are proposed.

Analysis of the causes and countermeasures of common problems in gravure printing from the process perspective

Analysis of the causes and countermeasures of common problems in gravure printing from the process perspective

Common problems in the processing of printed materials are: print line marks (knife wire, knife line), poor ink adhesion, dark tone level, poor gloss, color difference, half point, leakage, blocking plate, pinhole, turtle pattern, residual solvent, etc.. In this article, we will take poor gloss and residual solvent as an example, and briefly explain the causes and solutions from the perspective of the printing process.

The five basic requirements of the printing plate cylinder, must do!

The five basic requirements of the printing plate cylinder, must do!

As the saying goes, the print "three points in the printing, seven points by the plate". What to pay attention to during the printing plate making process, how to choose and test the plate cylinder, is the premise of the quality assurance of printed products. This article will introduce the basic requirements for gravure printing cylinder selection and processing, plate plating and cylinder grinding, for reference.

Fine gravure printing is three parts by printing, seven parts by plate making!

Fine gravure printing is three parts by printing, seven parts by plate making!

It is often said that "seven points by the plate, three points by the printing", no doubt that the quality of the printing plate is critical for gravure printing. Among them, the plate cylinder processing accuracy on the impact of overprinting is particularly important.

Application of pre-registration technology in gravure printing presses

Application of pre-registration technology in gravure printing presses

The concept of pre-registration technique: First I want to explain the concept of "pre-registration", so what is "pre-registration"? We believe that the first printing material is not stretched, pre-loading plate, automatic pre-alignment, open horizontal alignment, longitudinal addressing can play automatic speed up register.
