Abstract

A variety of sources of variability cause inconsistent color reproduction in Inkjet Printers. Difference in the size of drops ejected, paper type and environmental conditions, to name a few, can lead to big differences in the printed colors. This paper describes a system based on sensing the color shift with respect to pre-determined color targets and compensating for it. The system relies on a combination of several components that work together to provide the best results while minimizing cost and user intervention. The key components are: a built-in sensor tuned to get estimates of ink density in the particular ink/media system, a sensor characterization process, a user triggered calibration process that senses and corrects the color errors and a set of color profiles built in the printer's driver.A periodical calibration of the printer/media system ensures consistent and accurate colors in the output. The performance achieved is currently the leading edge in inkjet printers, enabling color accuracy errors below 4 dEab* maximum, which is at least 50% more accurate than most Inkjet printers.
