Description

Technical Field

[0001] The utility model relates to the field of developing equipment, in particular to a screen printing film developing equipment. Background Art

[0002] The silk screen is a very critical component in the silk screen printing process. Film is also called film. In the printing industry, film usually refers to a film used for plate making. It is output by equipment such as photosetters and carries a negative or positive image of the graphic information to be printed. Its main function is to serve as an intermediate medium to accurately transfer the designed graphic content to the printing plate (such as silk screen, offset printing plate, etc.), thereby achieving accurate printing reproduction.

[0003] In printing plate making, film is usually used as an intermediate medium to transfer design images to printing plates. The purpose of film development is to clearly show the potential image on the film after exposure, so that the film can be used to make accurate printing plates (such as silk screen screens, offset printing plates, etc.) in the future. The silk screen film needs to be developed using developing equipment and developer.

[0004] However, the existing developing equipment is not conducive to regulating the temperature of the developing solution when in use. When the temperature is low in winter, the developing solution will be in a low-temperature state. Crystallization is easily generated in the low-temperature developing solution. After crystallization in the developing solution, it will affect the normal development of the silk screen film, which is not conducive to the use of the developing equipment.
