Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing, in particular to a printing in-line back coating device. Background Technique
[0002] Back coating of the printing line is a term in the printing industry, usually used to describe a special treatment process of printed matter. Back coating refers to a special covering or coating treatment on the back of the printed matter. By applying a layer of back coating on the back of the paper, the stability and flatness of the paper can be increased, making the printed matter more flat and not easy to warp.
[0003] Ordinary back coating devices usually do not have an adjustment function. When the back coating device back coats papers with different thicknesses, different printing rollers need to be replaced to back coat the papers due to the different paper thicknesses, resulting in a decrease in work efficiency. Therefore, a printing in-line back coating device is proposed to solve the above-mentioned problems. Content of the Utility Model
