Sažetak
Our 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 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 an system for identifying, matching and controlling ink colours in 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 controlling. In order to examine the optical modifications, the samples were exposed to elevated temperature and UV/VIS lamp radiation. The FTIR spectroscopy was additionally used for the characterization of printed inks before and after ageing.
