Abstract
Provided are a method, system, and an article of manufacture for registration calibration of a printer. An application prints reticle patterns on a printed page. An imaging device creates a digital image of the printed reticle patterns. If color registration on the printer is improper, the digital image exhibits interference patterns. The application compares the interference patterns to the reticle patterns, and based on the results of the comparison adjusts the color registration of the printer.
Claims38
A method for registration calibration of an operating printing device, the method comprising:
- printing a test pattern on a print medium by a plurality of printing stations that each print with a color printing medium;
- generating a digital image of the printed test pattern by an imaging device;
- analyzing an interference pattern extracted from the digital image, wherein analyzing the interference pattern is performed between printing stations before the printing stations have printed with all colors of the printing medium;
- and
- based on the interference pattern, calibrating the printing device.
A method for registration calibration of an operating printing device, the method comprising:
- printing a test pattern on a print medium;
- generating a digital image of the printed test pattern by an imaging device;
- analyzing an interference pattern extracted from the digital image, wherein analyzing the interference pattern further comprises:
- isolating via edge detection the interference pattern from the digital image;
- comparing the interference pattern to the test pattern;
- and
- based on the comparison, determining if a calibration of the printing device needs to be performed;
- and
- based on the interference pattern calibrating the printing device.
A method for registration calibration of an operating printing device, the method comprising:
- printing a test pattern on a print medium, wherein the printing device has a plurality of printing stations, wherein the test pattern is printed on the print medium by the plurality of printing stations, wherein the printing stations print with a printing medium, wherein the printing medium is from the group consisting of ink or toner, wherein the printing is with at least colors from the group consisting of cyan, magenta, black, highlight and other colors;
- generating a digital image of the printed test pattern by an imaging device, wherein the imaging device generates the digital image of the printed test pattern after the test pattern has been printed by at least two of the printing stations;
- analyzing an interference pattern extracted from the digital image, wherein analyzing the interference pattern is performed between printing stations before the printing stations have printed with all colors of the printing medium;
- and
- based on the interference pattern, calibrating the printing device.
