Sažetak

This study focuses on the research of changes in the optical characteristics of selected
offset inks (Yellow, Red 032, Process Blue and Black) printed as a part of Pantone
colour book. These changes that occur as a result of natural and accelerated ageing
(caused by thermal and UV/VIS radiation) were observed through reflectance
spectra in the visible region. A Pantone colour book is a system for identifying,
matching and controlling ink colours in the graphic industry. This colour book
is the international reference for accurate colour communication. The durability
of colours and its unchanged quality play an important role in ensuring accurate
colour communication and control. In order to examine optical modifications, the
samples were exposed to elevated temperatures and UV/VIS lamp radiation. The
FTIR spectroscopy was additionally used for the characterization of printed inks
before and after ageing.
