Description

[0001] The present application relates to the technical field of screen printing, in particular to a screen printing production device and production method for multi-color screen printing. BACKGROUND

[0002] Screen printing is a widely used printing technology, and during printing, the paste is transferred to the printing material through the mesh hole of the printing plate text part by the extrusion of the squeegee, forming the same text as the original; multi-color screen printing is a way of printing different colors of paste on the printing material by screen printing. Screen printing is widely used, and in the process of pencil processing, multi-color screen printing is needed on the surface of the pencil by screen printing. A screen printing production device is needed for multi-color screen printing of pencils.
