Abstract

Disclosed are methods and systems of processing work flow associated with a print job including Specialty Imaging such as UV and/or IR encoding. According to one exemplary embodiment, a printing system controller accesses a spatially structured ink composed of a plurality of non-overlapping primitive spot colors to render Specialty Imaging effects along with other images and text associated with the print job.
