In xerographic printing, stabilization of the color reproduction function (CRC) or the tone reproduction curve (TRC) for the color separations are critical for achieving color consistency. This problem is challenging because: 1) there exist only a small number of actuators to stabilize a potentially infinite dimensional TRC; 2) only a small number of tone / color test patches can be printed and measured at a time. The first issue is addressed by a curve-fitting TRC stabilization controller based on Linear Quadratic (LQ) control with integral dynamics is proposed. It specifies particular tones or color that to be precisely controlled, while allowing other tones or colors to be close to the desired value. To address the second problem, time-sequential sampling is proposed to enable the time varying TRC or CRC to be reconstructed based on small number of samples. Experimental and simulation results verify the adequacy of the approach.

  • 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.
