Abstract
A method of calibrating a printer is disclosed. The printer prints a plurality of patches using know color values. At least two patches of each color are printed. The patches are measured to determine a measured color value for each patch. The measured color values are checked for validity. The printer is calibrated using only the valid measured color values.
Claims14
A method for calibrating a printer, comprising:
- printing, with the printer, a plurality of patches onto media using a plurality of known color values, where there are at least two patches of each of the plurality of known color values;
- measuring a color value for each of the plurality of patches;
- determining if each of the measured color values is valid;
- calibrating the printer using only the measured color values that are determined to be valid.
1 more element
A printer, comprising:
- a marking engine for marking media;
- a media transport system for moving media through the marking engine;
- at least one scanner to scan the marked media and measure a color value of the marked media;
- a controller comprising at least one processor and memory;
- code stored in the memory, the code, when executed by the at least one processor, causing the printer to run a calibration routine;
- the calibration routing causing the printer to print a plurality of patches onto media using a plurality of known color values, where there are at least two patches of each of the plurality of known color values;
- the scanner measuring a color value for each of the plurality of patches;
- the controller determining if each of the measured color values is valid;
- the controller calibrating the printer using only the measured color values that are valid.
