RELIEF PRINTING PLATE

摘要

A relief printing plate (02) comprises a baseplate (021). The baseplate (021) is divided, by a first axis (x) and a second axis (y), into four equal-area regions. The baseplate (021) is provided with a plurality of strip-shaped protrusions thereon. A gap exists between any two of the strip-shaped protrusions. The first axis (x) is parallel to an extension direction (x1) of the relief printing plate (02), and the second axis (y) is parallel to a non-extension direction (y1) of the relief printing plate (02). The plurality of strip-shaped protrusions comprise a first strip-shaped protrusion (022) provided in any region of the four regions. One end of the first strip-shaped protrusion (022) adjacent to a first edge (g) of the baseplate (021) inclines toward a center of the first edge (g) of the baseplate (021). The first edge (g) of the baseplate (021) is an edge of the baseplate (021) parallel to the extension direction (x1) of the relief printing plate (02) and adjacent to the first strip-shaped protrusion (022). The relief printing plate (02) improves printing uniformity of a PI solution.
