Problems solved by technology

In the case of the same mesh number, there will be different opening ratios and thicknesses to achieve different printing ink thicknesses and different printing effects, which cannot be solved in the prior art
[0004] At present, the printing rotary screen commonly used in the market, one is a standard screen, the general production steps: mold - primary plating - secondary plating - nickel screen forming, the circular mesh number is 25, 40, 65, 80, 100 , 125, can only print low-grade patterns; the other is welded by flat screens above 255 mesh, with seams, which affects the printing effect, its service life is short, it is not suitable for high-speed printing, and it brings inconvenience to production
In the process of making the rotary screen, due to technical limitations, when the mesh number of the rotary screen is to be increased, the opening rate will decrease, and the slurry penetration of the rotary screen will decrease.

Abstract

The invention provides a method for producing a printing rotary screen with large mesh number, in particular to a method for producing a printing rotary screen with the mesh number of 205-405, which is mainly used for producing the rotary screen and belongs to the printing rotary screen production field. The method is simple, easy in operation and effective in controlling the percentage of open area and thickness in the condition of the same mesh, no joint exists, the stability is good, the printed ink thickness is even in printing, the printing quality is good, and the service life of the screen is prolonged.

Description

technical field [0001] The invention relates to a method for manufacturing a high-mesh printing rotary screen, specifically a method for manufacturing a 205-405 mesh printing rotary screen, which is mainly used for making rotary screens and belongs to the field of printing screen production. Background technique [0002] There are many classifications of screen printing, which can be divided into flat screen printing and rotary screen printing according to the structure. Rotary screen printing is a kind of rotary screen printing. Rotary screen printing can be used for printing of various materials. It can achieve fine lines, thick ink layer, strong three-dimensional effect and other effects, which are the effects that other printing methods cannot achieve. It is more and more widely used in the printing field. [0003] With the development of the rotary screen printing industry, the demand for printing rotary screens is also increasing. At the same time, the requirements fo...
