Color-to-color correction in a printing system

摘要

Methods and systems for performing color-to-color correction for printing multiple print jobs comprise receiving a first print job, wherein the first print job has one or more documents, receiving a second print job, wherein at least a portion of one of the documents in the second print job is different from a corresponding document in the first print job, and printing a copy of the first print job. One or more processors are used to determine a plurality of color plane registration errors produced during the printing of the copy of the first print job, local color plane correction values based on the plurality of color registration errors, and a difference between the corresponding documents in the first print job and second print job. When the amount of difference is less than a predetermined threshold, the local color plane correction values are used to print the second print job.

1. A method for performing color-to-color correction for printing multiple print jobs, comprising:
receiving a first print job, wherein the first print job has one or more documents; receiving a second print job, wherein at least a portion of one of the documents in the second print job is different from a corresponding document in the first print job; printing a copy of the first print job; using one or more processors to: i) determine a plurality of color plane registration errors produced during the printing of the copy of the first print job; ii) to determine local color plane correction values based on the plurality of color registration errors; and iii) to compute a difference between the corresponding documents in the first print job and second print job; when the amount of difference is less than a predetermined threshold, using the local color plane correction values to print the second print job; and when the amount of difference is more than the predetermined threshold, determining matching portions of the first and second print job, printing the matching portions of the second print job using the local color plane correction values for the corresponding portion of the first print job, and printing non-matching portions of the second print job without using the local color plane correction values of the first print job.
