Abstract
A printing plate includes, on the printing surface of a raised part, grooves passing through from one side to another thereof. Preferably, the grooves are parallel to each other and equally spaced apart. More preferably the raised part is in the shape of a nearly-rectangular frame, and the grooves are provided such that one side of the near-rectangle and the longitudinal direction of the grooves form an angle of 45°.
Claims15
A printing plate comprising a raised part for transferring printing substance to a printing substrate, wherein
- said raised part is formed to extend linearly in plan view,
- said raised part is shaped as a rectangular frame in plan view,
- said raised part has at least one groove formed on its printing surface,
- said at least one groove is formed to pass through from one side to another side of said raised part, wherein said groove has a triangular cross section.
A method of relief printing comprising:
- the step of printing by pressing, on a printing substrate, a printing plate including a raised part,
- said raised part is formed to extend linearly in plan view,
- said raised part is shaped as a rectangular frame in plan view,
- said raised part having a plurality of grooves on a surface for transferring printing substance,
- wherein said raised part is shaped as the rectangular frame, said grooves are linear grooves parallel to each other and equally spaced apart, and the printing substance to be printed onto said printing substrate is a sealing material,
- said plurality of grooves passing through from one side to another side of said raised part;
- and
- the step of transferring printing substance to the printing substrate by disposing said printing plate on a perimeter surface of a cylindrical place cylinder and rotating said plate cylinder,
- wherein the method of relief printing is performed by using a flexographic press.
