Representation of Primary Color Tone Reproduction Curves for their Stabilization
Abstract:This paper proposed and compared different methods of representing the color tone reproduction curve (TRC) for stabilization of the monochorome xerographic printing process. TRC stabilization is vital in maintaining high consistency in color printout. Colors are typically represented by a 3-dimensional representation such as the CIELAB or CIEXYZ colorspaces. For stabilization control, the 3-dimensional representation is redundant due to the fact that limited actuators authority would not account for all the degree of freedom in the data representation. A 1-dimensional reparameterization of the 3-dimensional representation is better suited for the stabilizing control. The proposed parameterization methods involved projection of the 3-dimensional representation onto a parameterization curve. An empirical-based and model-based approach was used to describe this curve. Simulation and experimental results are presented to demonstrate the performance of the different parameterization method subject to measurement noise.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
