Abstract
A gravure printing plate capable of printing straight image lines with high accuracy. The gravure printing plate is a gravure printing plate for printing an image line including a straight image line constituted by a first contour line and a second contour line. The gravure printing plate includes a cell group including a reference cell for printing the first contour line, and image line composition cells present in a projection portion in which the reference cell is projected up to the second contour line in a direction orthogonal to the first contour line. The dimension of each cell of the reference cell and the image line composition cells in the same cell group in an extension direction of the first contour line is within ±5% of an arithmetic average value of the reference cell and the image line composition cells in the same cell group.
