This paper briefly reports on first part of research in the course of which an attempt was made to evaluate the light fastness of computer prints. An attempt was also made to evaluate the impact of inks and toners used in computer printers on printed paper.

Changes to computer printer colors occurring in the course of exposure in Xenotest 105S were determined by measuring the values of L*, a*, and b* coordinates in the CIELAB color system. Changes were found to be substantial. No substantial influence of computer ink on the pH of the studied papers was established, while the influence on strength properties (tear index and breaking length) was found to vary.

Treating this research as preliminary work, the authors recognize the possibility of greater color light fastness only in the case of black-and-white prints made on the tested laser printer.

  • 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.
