<P>PROBLEM TO BE SOLVED: To provide automatic systems and techniques for producing custom screen printed products based on digital images without manual editing activities. <P>SOLUTION: Data processing methods provide a work flow for producing the custom screen printed products based on the digital images. Disclosed techniques include a work flow for: receiving user-supplied images and transforming the images into color separation data and related metadata that can drive screen printing, including previewing the appearance of the products as they will appear when screen printed, for user approval; finding key color components using a filtering and grouping approach; image resolution limiting; structured error diffusion halftoning with an improved random number generator for use in adding blue noise; error diffusion dot spread correction; and others. <P>COPYRIGHT: (C)2012,JPO&INPIT |
