Abstract
A method of screening a continuous tone image into a halftone representation for a flexographic printing operation can compensate for characteristic printing problems in highlight areas by selectively placing non-printing dots or pixels proximate highlight dots. The non-printing dots or pixels raise the printing relief floor in the highlight areas providing additional support for marginally printable image features.
Claims23
A memory for storing data for access by a flexographic printing system, wherein the memory comprises machine-readable data elements adapted to specify to the flexographic printing system at least one marginally printable image feature, at least one non-printing feature proximate the marginally printable image feature, and at least one non ink-transferring background area.
A memory for storing data for access by a relief printing system, wherein the memory comprises machine-readable data elements adapted to specify to the relief printing system:
- a marginal halftone dot wherein the marginal halftone dot tends to produce a marginally printable relief dot in a relief printing plate;
- and
- a configuration of non-printing enabled halftone pixels, proximate to the marginal halftone dot, to improve the printability of the marginally printable relief dot and wherein the configuration of halftone pixels is based on a characteristic of the marginal halftone dot.
