Description

Rolling device for printing screen

Technical Field

The utility model relates to a printing half tone technical field especially relates to a roll-in device that printing half tone was used.

Background

The silk screen printing refers to the production of silk screen printing plate with picture and text by using silk screen as the printing plate base. The basic principle that the meshes of the image-text part of the screen printing plate can be permeated by the coating and the meshes of the non-image-text part can not be permeated by the coating is utilized to print. At present, paint is scraped back and forth by a scraper mostly when screen printing is carried out, the scraper is easy to lose due to the separation between the scraper and the screen, and certain deviation of printing paper is easy to occur due to external factors such as human body mistaken touch or wind blowing in the printing process, so that the position of a printed pattern can be greatly deviated. We have therefore developed this and have proposed a roller assembly for a printing screen.
