Diagnosis for Differential Gloss in Color Hard Copy Outputs
Abstract:For hard copy technologies using separate multiple layers of colorants to form the final output, differential gloss is a quality attribute that the ink formulator or toner process engineer must manage. In 2001, the standards committee from INCITS W1.1 issued in 2001 40-patch multicolor test target for the evaluation of differential gloss. The use of this target typically involves reporting the maximum and minimum gloss readings among the 40 color patches. This paper proposes a methodology to interpret the extent of differential gloss in terms of just noticeable differences, or JNDs, and to diagnose how gloss level changes with color or lightness levels. Examples of several electrophotographic and inkjet outputs will be used to illustrate the standard target and the methodology.

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.
