Description

The present invention relates to a metal printing plate in which a metal plate is mounted on a printing plate frame.

[Prior Art] A conventional metal printing plate uses a screen printing plate main body in which a gauze is attached to a printing plate frame, and the metal plate is bonded and fixed to a substantially central portion of the gauze with an adhesive.

Thereafter, after removing the gauze at the metal plate portion, a photosensitive emulsion is applied to the gauze on the outer peripheral portion of the metal plate and exposed to light, and the gauze is formed by filling the gauze.

For this reason, there is a drawback that it takes time and effort to produce a metal printing plate, resulting in an increase in cost.

In addition, since a metal plate cannot be replaced and used, a screen printing plate body that costs as much as 40,000 to 50,000 yen is required to make a metal printing plate using the required screen printing plate body for the required metal plate. There was a drawback that it could not be used and the equipment cost was high.

Further, the transportation of the metal printing plate from the manufacturer of the metal printing plate to the printing maker has to be performed for each large metal printing plate, and there is a disadvantage that the transportation work is troublesome and the transportation cost is increased.
