Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a four-color printing machine. Background Art

[0002] A four-color printing press specifically refers to a printing press that uses black, medium blue, brown, and green inks to achieve a lithographic printing method for map reproduction. It uses the three primary colors of the subtractive color method (yellow, magenta, cyan) and black for printing, which makes it easier to enrich the appearance of products and makes it easier for people to use a four-color printing press for outer packaging printing or product printing.

[0003] The existing four-color printing machine uses ink for printing. However, the ink attached to the printing cylinder will dry up after the printing cylinder stops. As a result, more and more ink will be attached to the printing cylinder over a long period of time, resulting in blurred printed parts, reduced printing quality, and extremely cumbersome cleaning of the printing cylinder. For this reason, we have proposed a four-color printing machine. Utility Model Content
