Flexographic printing plate and method for manufacturing same

Abstract

An object of the present invention is to provide a flexographic printing plate having excellent printing durability and hardly causing ink picking, and a method for manufacturing the same. The flexographic printing plate of the present invention is a flexographic printing plate in which an image area satisfies a requirement C. Requirement C: assuming that a shading of an image expressed by the image area is formed by halftone dots having a screen ruling α, in a case where a region of the image area corresponding to a region where a diameter of the halftone dots is less than 17 μm is defined as X, a region of the image area corresponding to a region where a diameter of the halftone dots is 17 μm or more and 45 μm or less is defined as Y, and a region of the image area corresponding to a region where a diameter of the halftone dots is more than 45 μm is defined as Z, in X, the shading is formed by irregularly arranged halftone dots P having a diameter of 17 μm or more and 45 μm or less, in Y, the shading is formed by irregularly arranged halftone dots P having a diameter of 17 μm or more and 45 μm or less, or by halftone dots Q having the screen ruling α, and in Z, the shading is formed by halftone dots Q having the screen ruling α, provided that a diameter of halftone dots Pmin having the smallest diameter is equal to or less than a diameter of the halftone dots Q.
