Issues in Evaluation and Standardization of Light Fading Tests of Ink Jet Materials
Abstract:The purpose of this study is to reach a better understanding of the complex fading behavior of ink jet prints and to demonstrate the difficulties in providing reliable tests. Test conditions chosen for this research were: high-intensity fluorescent light (framed and unframed samples), airflow, and ozone and nitrogen dioxide to better predict the influence of possible environmental pollutants. Two ink sets, a dye-based and a pigmented one, printed on two different media (a photo glossy and a matte paper), were tested. The samples were read with a spectrophotometer to get an overview of the fading behavior over the whole spectrum. An additional advantage of this approach is to not be limited to the filters used in densitometers, because they are not ideal for the inks used for ink jet printing today. The fading behavior of the various ink concentrations of the samples were monitored and described over time. These data lead to a more detailed description of the fading process than normally published data showing only an endpoint for one specific ink concentration. It is crucial to describe the fading processes as accurately and completely as possible during the time of development of ink jet materials. Advantages and disadvantages of various methods for describing the fading behaviors will be discussed.

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.
