Patent ID: 8319202

Claim:
A computer-implemented method for performing color registration on template media having template markings thereon, wherein the method is implemented in a computer system comprising one or more processors configured to execute one or more computer program modules, the method comprising: sensing the template media using a linear array sensor positioned along a process path of a web to obtain first image data; printing a test pattern on the template media; sensing the template media along with the test pattern printed thereon using the linear array sensor to obtain second image data; transforming the first image data and the second image data into an absorbance space to obtain a first absorbance and a second absorbance, respectively; determining a difference between the first absorbance and the second absorbance to obtain an output absorbance, the output absorbance being representative of absorbance corresponding to the test pattern; transforming the output absorbance into a reflectivity space to obtain an output data, the output data being representative of image data of the test pattern; determining a process direction misregistration and a cross-process direction misregistration from the output data; and adjusting a cross-process position and a process position of print heads based on the process direction misregistration and cross-process direction misregistration to provide accurate color registration on subsequent template media.
