Color Aspects of Variable Data Proofing

Beretta, Giordano

HPL-2004-236

Keyword(s): variable data printing; custom printing; pre-flight checking; color perception

Abstract: The Internet in combination with digital presses has allowed the geographical distribution of manufacturing printed materials. An increasing number of printed pieces is customized for the recipient; when each printed piece is different, conventional proofing fails, because it is impossible to proof the entire print job. One frequent problem in automatically generated pieces is the readability of one page element on top of another element; the color combination can be unreadable or clash. I propose simple algorithms to automatically detect and correct color discriminability problems in variable data printing. Notes: Copyright SPIE. To be published in and presented at IS&T/SPIE's 17th Annual Symposium on Electronic Imaging, 16-20 January 2005, San Jose, CA
