Abstract
A gravure printing plate is formed by a plurality of concave portions called 'cells', arranged in vertical and lateral directions, four sides of each generally square cell being surrounded by walls. A 'cell group' is formed of one core cell and four sets of paired cells adjacent to each other arranged to surround the core cell. A notched portion is formed in either one of two intersections of a wall and another wall intersecting therewith on the wall separating the paired cells. The positions of the notched portion is selected to be in point symmetry about the core cell. The direction of flow of a quick-drying ink, during use with the gravure printing plate, becomes random in the vertical and lateral directions in the cell group due to the notched portions, hence mottling of the ink can be prevented.
