Abstract
A color printer includes a media transport system arranged to feed print media along a media transport path; a print engine disposed at the media transport path; a controller arranged to calculate an amount of coverage for each pixel and for each process color of an image to be printed on the media, and to control the print engine on the basis of the calculated amount of coverage; a temperature sensor; and a color correction module arranged to determine a correction of the amount of coverage on the basis of a temperature detected by the temperature sensor. The temperature sensor is arranged at the media transport path upstream of the print engine for detecting the temperature of the media as they reach the print engine.
Claims8
A color printer comprising:
- a media transport system arranged to feed print media along a media transport path;
- a print engine disposed at the media transport path;
- a controller arranged to calculate an amount of coverage for each pixel and for each process color of an image to be printed on the media, and to control the print engine on the basis of the calculated amount of coverage;
- a temperature sensor;
- a color correction module arranged to determine a correction of the amount of coverage on the basis of a temperature detected by the temperature sensor;
- and
- at least a second temperature sensor arranged upstream of the first temperature sensor,
- wherein the temperature sensor is arranged at the media transport path upstream of the print engine for detecting the temperature of the media as the media reaches the print engine, and
- wherein the color correction module is arranged to determine the correction of the amount of coverage on the basis of a temperature estimate that is obtained by correcting the temperature measured by the second temperature sensor in accordance with a previously detected deviation between the temperatures which the first and second temperature sensors have detected for the same sheet.
