Influence of Dye Structure on Permanence
Abstract:The light fastness behavior of several classes of colorants was investigated on different ink-jet media. Their sensitivity to ink dilution and to environmental humidity is demonstrated. Cross-coupling effects are found for certain combinations of colorants. Most observations can be explained by a dye-aggregation mechanism that is more or less affected by the experimental parameters. A specific layer design is shown to improve light stability for certain dyes.

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.
