Abstract

See full text

Apparatus is described that comprises a printer carriage (100), comprising a printhead (105), at least one sensor (101, 102) for scanning an image deposited on a print media by the printhead (105) and a spectrophotometer (104) connected to the at least one sensor (101, 102) for generating data based on a reference image (120) on a test print media (110). The sensor (101, 102) is calibrated based on the generated data to detect a specific ICC profile, and wherein, in use, the sensor (101, 102) scans and digitizes an image of a final print media as the image is being printed on the final print media; and wherein the sensor (101, 102) is connected to a controller (106) that performs image quality analysis of the digitized image to determine whether colour deviation has occurred.
