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.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
