A kind of laser engraving type screen making method

Abstract

The invention discloses a manufacturing method of a laser engraving type screen printing plate. The manufacturing method comprises the following steps that 1, silk-screen weaving is performed; S2, a net is tensioned; S3, a photosensitive film is prefabricated; S4, the photosensitive film is attached; S5, a torn film is cut; and S6, laser engraving is performed. According to the manufacturing method, the pattern is formed by changing a traditional film exposure mode, and laser is changed into a mode that the laser is used for carving photosensitive glue on screen yarn, so that the influence ofthe temperature and humidity of a negative film caused by the environment is avoided, the size of the pattern area can be changed during exposure, the printing effect at the later stage is influencedby means of laser engraving, the precision of the pattern size is ensured, and the problem that the photosensitive glue on other areas on the screen yarns does not need to consider the later-stage cleaning difficulty of the photosensitive glue in the pattern area is solved; and strong ultraviolet light can be used for irradiating the second-layer light-sensitive adhesive on the screen yarns, so that the second-layer light-sensitive adhesive is firmer and does not need to consider the risk of transition exposure.

Description

technical field [0001] The invention relates to a method for making a laser engraved screen plate. Background technique [0002] Screen printing technology is an ancient civilization and a long-lasting industry, which is widely used in people's production and life. Especially in recent years, with the high development of the electronics industry, the screen printing process has been well applied, and a vibrant scene has emerged. The basic structure of the screen is eternal, that is, the screen frame, the missing printing screen and the photosensitive material for printing are integrated, and the three are indispensable; and at present, exposure on the screen The method is generally to paint photosensitive glue on the mesh, then heat and cure the photosensitive glue on the mesh, and then expose the photosensitive glue on the mesh through negative film exposure, and get the screen printing pattern after washing.

Especially in recent years, with the high development of the electronics industry, the screen printing process has been well applied, and a vibrant scene has appeared. The basic structure of the screen is eternal, that is, the screen frame, the missing printing screen and the photosensitive material for printing are integrated, and the three are indispensable; and at present, exposure on the screen The method is generally to paint photosensitive glue on the mesh, then heat and cure the photosensitive glue on the mesh, and then expose the photosensitive glue on the mesh through negative film exposure, and get the screen printing pattern after washing. The photosensitive adhesives of the above methods are all directly painted on the mesh, the stability is not good, the photosensitive adhesive is unevenly painted and the thickness cannot be controlled, which affects the printing performance of the printed pattern; in addition, the existing ones are generally exposed through negatives The way to print patterns on the photosensitive adhesive, but in this way, because the film is affected by the temperature and humidity of the environment, the size of the pattern area will change during exposure, which will affect the printing effect in the later stage.
