1. A method for patterning a flexoblank to form a flexoplate comprising:
curing a first surface of a flexoblank, wherein the first surface comprises a backing, wherein curing the first surface forms a floor on the first surface, and wherein curing comprises emitting ultraviolet (UV) radiation with a plurality of wavelengths between 250 nm-600 nm and a curing dosage from 0.3 J/cm2 to 1.0 J/cm2; disposing a mask on a second surface of a flexoblank, wherein the second surface is opposite the first surface; curing the second surface to form a pattern on the second surface, wherein curing the second surface comprise using UV light at a dosage between 5 J/cm2 and 25 J/cm2; wherein forming the pattern comprises forming a plurality of lines, wherein the cross-section of each of the plurality of lines is one of a square, a rectangle, a triangle, and a trapezoid, wherein a plurality of valleys are formed in between each set of lines of the plurality of lines, and wherein the valley depth is between 5-20 microns. |
