Abstract

A process for creating a mask for making a printing plate from an unexposed flexographic plate having a masking layer. The process includes providing image information as a first screen having a first plurality of pixels and defining openings in the masking layer in accordance with the image information by superimposing on at least a portion of the image information a base pattern of equally sized spots. Each spot corresponds to an imaged discrete element represented on the mask and has a size corresponding to a smallest discrete element formed on the mask. The spots in the base pattern are aligned in horizontal rows and columns having a non-zero spacing between adjacent rows and columns. In at least a portion of the mask, a size for forming each imaged discrete element is selected such that each set of four neighboring imaged discrete elements has a non-imaged discrete area centered therebetween.
