The digital age may seem to have diminished the need for paper-based
document storage, but there are still many situations that call for color accuracy
in inkjet applications. Examples of these circumstances include: individuals
wishing to create photo albums from digital images, and any type of document
printed on archival papers. After taking digital photos and sending them to an
inkjet printer, people expect their photographs to maintain brightness, clarity,
and color. Documents printed on archival papers are intended for long-term
storage with little change in color. Light fastness of inks and papers is relevant
in all situations requiring document storage over a moderate period in
suboptimal conditions.
This paper focuses on the ability of pigment-based and dye-based inks to
maintain accurate color strength over time due to the exposure of printed
samples to simulated sunlight. It proposes the testing of a number of
