Description

Technical Field

[0001] The utility model relates to the technical field of printing plate rollers, in particular to an anti-jumping pre-printing plate roller. Background Art

[0002] Gravure printing, abbreviated as "gravure printing", is a platemaking technology in which images are carved into depressions on the surface. It first appeared in Europe in the 15th century. The sunken images and texts were carved out by hand on metal plates. When printing, ink was applied to the plate surface to remove the ink, and only the ink remaining in the concave part was transferred to the paper. Later, photographic etching gravure (formerly known as photogravure) and mechanical engraving gravure (including engraving with electronic engraving machines), laser engraving gravure, electron beam engraving gravure, etc. were developed. Although the currently used printing plate rollers can meet the printing needs, they still have defects in actual use. For example, the existing printing plate rollers often jump during the printing process, causing defects in the printing and resulting in the failure of the entire printing. Improvement is needed. Therefore, a pre-printed plate roller with anti-jumping is now proposed. Utility Model Content
