Patent ID: 10059138

Abstract:
Provided is a flexo printing plate which makes it possible to perform printing in which the discontinuity of density is not visually recognized by inhibiting the enlargement of halftone dots in the boundary between an image area having a low halftone dot rate and a non-image area. The flexo printing plate has a constitution in which the image area has a highlight halftone dot area having a halftone dot rate higher than 0% and equal to or lower than 10%, and within the highlight halftone dot area, among small dots constituting the highlight halftone dot area, at least one of the small dots adjacent to the non-image area that continues 10 mm or further from the edge of the highlight halftone dot area in a direction orthogonal to the edge has a distal end diameter smaller than the average of distal end diameters of the small dots in the highlight halftone dot area.
