Color ink jet printers have become extremely popular in homes and corporate offices thanks to technological improvements that deliver better image quality at higher speeds. With these improvements, ink jet printer users, including novices and experienced amateurs, are able to print with ease photographic quality images that are comparable to traditional silver halide photographs. Taking advantage of digital printing, the digital photographic market is expected to expand rapidly in the very near future. With this background, image permanence on ink jet recording prints is strongly desired, and this leads to the improvement of dye inks and media matching for ink as well as the development of new media that are optimized for pigment inks. The general approach that is taken for dye inks is to match the recording ink and the recording media in order to improve image permanence, employing photographic quality attained through the use of photooutput quality media. In the case of pigment inks, a variety of approaches are being studied, such as applying gloss and the pigment's own metamerism to attain photographic quality, employing the fastness of the pigments themselves.This paper reports on storage performance with respect to the effects of water, thermal, humidity, plasticizers, light and gases, for ink-jet recorded images which use dye inks and photo-quality recording media, and which have a level of image-quality equivalent to silver-halide photographs.
