Patent ID: 7826095

Claim:
A system for estimating color separation misregistration, comprising: a communication module having a first operative set of processor executable instructions, wherein the communication module is configured to receive a misregistration estimation patch raw data structure relating to a misregistration estimation patch marked on a substrate, the misregistration estimation patch being formed by first and second color separations, the first color separation marking the substrate with a first halftone pattern having a first halftone-frequency vector in a first direction and a second halftone-frequency vector in a second direction, the second color separation marking the substrate with a second halftone pattern having a first halftone-frequency vector in a first direction and a second halftone-frequency vector in a second direction, wherein the first and second halftone patterns form a moiré pattern, wherein deviation in at least one of said at least one of the halftone frequency paths and the moire pattern is indicative of a color separation misregistration; and an analysis module having a second operative set of processor executable instructions, wherein the analysis module is operatively connected to the communication module, the analysis module being configured to estimate color separation misregistration by processing the misregistration estimation raw data structure and generating a misregistration estimation processed data structure corresponding to a characterization of the color separation misregistration.
