Screen printing plate making method and related equipment

Abstract

The embodiment of the invention provides a silk-screen printing platemaking method and related equipment. The silk-screen printing platemaking method and the related equipment are used for improving the quality and efficiency of silk-screen printing platemaking. The method comprises the steps that a printing plate material is divided into an image area and a blank area according to size parameters of a to-be-printed image, the area of the image area is not smaller than that of the to-be-printed image, and the blank area surrounds the image area; controlling the emergent light to carry out reciprocating scanning on a pixel line where the image area is located along a straight line; in the scanning process of each row of pixels, emergent light in the direct imaging equipment is controlled to do accelerated or decelerated linear motion in a blank area where the pixel rows are located and do uniform linear motion in an image area; wherein during reciprocating scanning, emergent light is controlled to completely expose and cure the photosensitive or thermosensitive coating in the blank area to form edge sealing; and during uniform linear motion, the emergent light is controlled to expose the pixel exposure point positions in the image area, and the non-pixel exposure point positions are not exposed, so that a latent image of the to-be-printed image is formed.

Description

technical field [0001] The invention relates to the technical field of screen printing, in particular to a screen printing plate-making method and related equipment. Background technique [0002] Screen printing is referred to as screen printing. During printing, the ink is transferred to the substrate through the holes of the stencil through a certain pressure to form an image or text. The current silk screen plate making technology is plate making through film, or plate making through computer-to-plate technology. [0003] The surface area of ​​a printing plate in screen printing (for example, a photosensitive or heat-sensitive coating applied to the screen surface of the screen frame can be a printing plate) is often larger than the image area, which is often placed in the center of the screen frame. After the central area of ​​the screen frame is imaged, in order to prevent the slurry or ink from leaking from the edge of the squeegee surface to the printing surface duri...

Problems solved by technology

[0004] In the existing technology, cutting the tape separately or coating a special glue solution for curing requires the introduction of additional process operations, which is time-consuming and labor-intensive, and it is not easy to control the quality
