Abstract
A great amount of chromogenic film and prints
shows signs of fading and/or colour shift. This is
due to the lack of permanence of some chromogenic
dyes. For this reason, new methodologies
to accurately monitor colour change on chromogenic
reversal films are proposed. Based on
artificial ageing experiments, the fading rate
for dyes was assessed using a non-invasive
analytical technique: ultraviolet-visible (UV-Vis)
spectrophotometry with optical fibre probes.
Additionally, the samples were documented by
digitising the images before and after ageing.
This approach proved to be a powerful method
for dye fading monitoring.
