Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a metal mask printing plate used for printing with high dimensional accuracy.
[0002]
[Prior art]
Since conventional metal mask printing plates do not have elasticity, the metal mask with the printing pattern formed at the center of the ridge is bonded with an adhesive using a screen printing plate body with a ridge attached to the printing plate frame. After fixing by adhesion, the wrinkles at the metal mask portion are removed, and a photosensitive emulsion is applied to the wrinkles on the outer periphery of the metal mask, exposed, and filled with wrinkles.
[0003]
[Problems to be solved by the invention]
The conventional metal mask printing plate has the disadvantages that the work of attaching the metal mask to the printing plate frame is laborious and time consuming, and the cost is high, and the metal mask plate manufacturer with the metal mask attached to the printing plate frame There is a drawback that it has to be transported from the printer to the printing maker, which requires a lot of transportation work and increases the transportation cost.
