VOC Based End-Point Criteria for Lightfastness of Hardcopy Prints
Abstract:Historically printlife of hardcopy output prints has been based on endpoint criteria relative to changes in density (loss of density). In the past few years attempts have been made to establish acceptable colorimetric endpoints. These metrics have been based on Delta E or some variation of delta E. This presentation will discuss a psychophysical study conducted to determine objective metrics in a perceptually uniform color space. The study will also look at the capability of existing metrics to determine their validity. Primary and Secondary color tonescales as well as neutrals and memory colors (flesh, sky, foliage, and others) were used to identify tolerances around variations of these colors. Subjective response to 16 scenes from 12 output systems at various degrees of degradation were correlated to objective metrics determined using CIE2000 color difference formulae.

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.
