“…Whether such crosslinking can also occur in the present experimental conditions, and to what extent, is not known. The lack of degradation from formaldehyde exposure has been observed recently on other materials too, such as aged colour photographic prints [61] and soda silicate glass [62].…”

International audienceThe reactivity towards cellulose of various volatile compounds commonly released by paper was studied. Sheets of Whatman No. 1 (W1) and No. 40 (W40) were exposed to various concentrations of these compounds in vapour phase ranging from 20 to 80 ppm in closed vessels for 52 days in controlled ambient conditions, after which they were hygrothermally aged. The measured properties of the paper were copper number, degree of polymerization, zero-span breaking length, pH and yellowness index. The results showed that hydrogen peroxide was the most aggressive among the volatile compounds tested as it severely degraded W1 cellulose. The exposure of W1 to formic acid led to significant degradation, designating this volatile organic compound (VOC) as the most reactive toward cellulose among the carboxyl and carbonyl functionalized VOCs tested. On the other hand, acetic acid was found comparatively less reactive. Nitrogen oxides, which were produced up to 3 ppm from a side-reaction of the carboxylic acids with the magnesium nitrate used to control the relative humidity in the closed vessels, appeared to contribute significantly to the degradation despite their low concentration. Antagonistic effects were evidenced in binary vapour mixtures where the presence of aldehydes (formalde-hyde and acetaldehyde) counteracted substantially the degradation induced by the most reactive compounds. It was also shown that acetaldehyde, hexanal and furfural in individual exposures had little to no reactivity. Upon exposure to formaldehyde, the rate of glycosidic bond cleavage of cellulose induced by the ageing of W1 was significantly reduced

“…These problems have been addressed by several research teams and many new test methods have been proposed based on densitometric measurements of extended test targets, 6 colorimetry 7 or image analysis. 8 Worth noting is the comparative study of Fenech et al 9 , who justified the fitness of colorimetric measurements of dye degradation by direct comparison with rigid analytical chromatographic methods. However, none of these proposals has received a general acceptance articulated in the form of a new ISO standard for the evaluation of digital print permanence.…”

Gamut volume is one of the parameters generally used for the characterization of printers and other imaging devices. However, it can also be used for monitoring color print fading. Relative gamut volume changes plotted as a function of the exposure dose can be conveniently used to determine the fading rate and corresponding lifetime. Calculation of the gamut volume is a challenge on its own, as a set of isolated points in three-dimensional space does not define a unique body in any obvious way. This problem has been addressed using the quick-hull algorithm combined with a non-linear convexing transformation of the measured data points and subsequent determination of the convex hull. In this article, the optimal degree of convexing is determined empirically on an extensive set of 19 samples including essentially all presently used photoprinting techniques. The actual use of gamut volume changes for monitoring of color print fading is illustrated on selected samples. d

Three frequently used formulas and their power function modifications were used to calculate the colour differences after the exposure to light and to study the stability of ink jet prints by spectrophotometric measurements. The prints were exposed to the simulated daylight of different spectral composition at constant conditions of temperature and relative humidity. According to the results, the black prints were the least affected and the magenta prints exhibited the biggest colour differences. The most resistant have proven to be the prints on archival paper which contained no optical brightening agents. The presence of shortwave radiation between 320 and 300 nm additionally diminished the resistance of prints. The same conclusions were obtained regardless of the colour difference formula applied, with one exception. Generally, the CIEDE2000 formula performed the best, especially when comparing samples with a smaller colour difference.
