Manufacturing method of full-opening metal screen plate

By defining the load-bearing mesh layer and performing photolithographic electroforming deposition, squeegee surface roughening treatment, and nano-coating formation during the manufacturing process of fully open metal screen printing, the problems of tension transmission and pattern opening interference in the traditional fully open metal screen printing process are solved, ensuring the stability and consistency of printing.

AI Technical Summary

Technical Problem

Traditional fully open metal screen printing has several problems during the printing process, including: overlapping of the warp or weft threads of the mesh with the fine-width pattern openings, which obstructs the path of the ink; unclear boundaries when the metal pattern layer is combined with the load-bearing mesh, which leads to interference with tension transmission and pattern opening formation; coating thickness affecting the consistency of opening size; and unstable squeegee surface condition affecting the stability of repeated printing.

Method used

The fully open metal screen manufacturing method is adopted. By defining the effective printing area and the peripheral fixing area within the screen frame, a load-bearing mesh layer is formed. The fully open metal mesh is then formed on the metal substrate through photolithography and electroforming deposition. The polyester mesh in the effective printing area is removed, and the squeegee surface is roughened and a nano-coating is formed to ensure the separation of the pattern opening and the tension support, as well as the connection between pattern opening size compensation and surface treatment.

Benefits of technology

This achieves stable separation between screen tension bearing and graphic opening, avoiding interference between the screen and graphic opening, ensuring the consistency of graphic opening size and the stability of the squeegee surface, and improving the continuity and repeatability of printing.

Abstract

The invention relates to the technical field of precise printing screen manufacturing, in particular to a manufacturing method of a full-opening metal screen, which comprises the following steps: preparing a screen frame, polyester screen cloth and a metal substrate, and delimiting an effective printing area and a peripheral fixing area in the screen frame; the polyester screen cloth is stretched and fixed to the screen frame, and the part, corresponding to the peripheral fixing area, in the polyester screen cloth forms a force-bearing screen cloth layer; a metal substrate serves as a temporary bearing substrate, full-opening metal screen cloth is formed through photoetching and electroforming deposition, and the width compensation amount of a mask pattern is set according to the opening line width of a finished product pattern and the thickness of a follow-up nano coating; after being separated, the full-opening metal screen cloth is compounded and fixed with the force-bearing screen cloth layer, and the polyester screen cloth in the effective printing area is removed; and roughening the scraper surface of the full-opening metal screen cloth, and forming a nano coating on the scraper surface and the inner wall of the pattern opening. According to the method, a force bearing structure and a pattern opening structure are arranged in a partitioned mode, and the thickness of a coating corresponds to the line width control of a finished product opening.
