Herringbone microstructure surface pattern for flexographic printing plates

The process ofclaim 1, wherein the microstructure surface screen pattern has a first row of first elevated line segments, a second row of second elevated line segments, and a third row of third elevated line segments, the second row disposed adjacent to and between the first row and the third row, the first elevated line segments and the third elevated line segments oriented in a first direction, and the second row of elevated line segments oriented in a second direction different than the first direction, wherein at least some the first elevated line segments are aligned on a same diagonal line with at least some of the third elevated line segments.

A printing plate for printing ink on a substrate, the printing plate having a printing surface for receiving ink, the plate having a defined image area intended to print with ink and a microstructure surface screen pattern in the defined area forming the printing surface of the printing plate, the microstructure surface screen pattern comprising a plurality of rows each having a plurality of diagonal oriented elevated line segments having orientations alternating between a positive angle in one row and a negative angle in an adjacent row, wherein each line segment has a first end aligned with a middle portion of and spaced apart from a first line of a first adjacent row and a second end aligned with a middle portion of and spaced apart from a second line of a second adjacent row.
