Light Fastness of Ink Jet Prints on Modified Conventional Coatings

Kerr Gated Resonance Raman Spectroscopy In Light Fastness Studies Of Ink Jet Prints

Resonance Raman spectroscopy offers several advantages in the studies of ink jet prints stemming from its inherent selectivity and sensitivity. These include the possibility to obtain direct information on the chemical interactions between the paper and ink that play a major role in long-term print fastness. However, resonance Raman techniques can suffer from obtrusive fluorescence from coloran...

Water Fastness of Ink Jet Prints on Modified Conventional Coatings

This paper was selected as the 2005 IS&T Itek Award for outstanding original student publication in the field of imaging science and engineering (full version published in JIST 48 #2). In order to produce color ink jet prints with good fastness properties, the use of special, coated papers is generally essential. This study examined the water fastness of ink jet prints using experimental coated...

Improving light fastness of natural dyes on cotton yarn

The objectives of this study were to evaluate the light fastness of selected natural dyes (madder, weld and woad) and the effect of some commonly used antioxidants and UV absorbers on the light fastness of these dyes. The photofading rate curves of madder and weld fixed on cotton correspond to type II fading rate curves described by Giles. These results are in concordance with those of Cox-Crew...
