Lightfast Ink Jet Images
Ink jet printing is a system. To get high quality images that last as long as customers want, you must match ink, media, printhead, printer, software operation and settings, posttreatment material and processes, and display conditions. To project ink lifetimes you must know the ink and media, and must understand how to project to real conditions from the lifetime reported at standard conditions.
Early ink jet dye inks had short lifetimes – even under dim lighting. Recent dye inks have extended lifetimes – but only under limited display conditions. Under real world conditions, a sizeable percentage of dye images will fade much sooner than the customer expects. Will these new inks meet customer expectations or will they disappoint so many customers that it will hurt business?
Pigment inks will last years outdoors and generations indoors; but can you get the printer reliability, color gamut, and image quality needed for quality images? Pigment inks in the right system give a robust printing process that produces high quality images with all the color saturation that customers require. These inks are as lightfast as the paints used by the artists who painted great masterpieces hundred of years ago and are still full of color today.
This paper will show how to relate reported lightfastness data to various display conditions. You will be able to project image life under the customer's expected display conditions. It will also examine some market perceptions about pigmented inks and high quality images. Finally, you will see tips and tricks for printing top quality, color saturated images with today's pigmented inks.

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.
