Abstract:

The objective of these experiments is to determine the lightfastness properties of various inks and most common digital printing methods. Lightfastness is the degree to which a dye or ink resists fading due to light exposure. Each ink has a different degree of resistance to fading by light. Because light is energy, the energy that is absorbed by pigmented compounds degrades the compounds or nearby molecules. The experiments described in this document involve printed samples subjected to equal amounts of sunlight exposure using accelerated methods. Statistical analysis comparing before and after data include average color change in terms of ΔE and overall gamut volume is compared. From these calculations, resistance to lightfastness can be accurately quantified.

  • 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.
