Production of Security Printing by Means of Themochromic and Conventional Offset Inks

Popis výsledku v původním jazyce

The aim of this work was to create patterns consisting of two parts. One part is a selected combination of CMY frational area coverage with full overprint of thermochomic (TC) offset ink and second part is a computed CMY simulation to match the first part in colour appearance. As first, different binary combinations of C, M, Y were printed with overprint of TC ink with full area coverage. The patches were measured by spectrophotometer to obtain reflectance spectra and consequent colorimetric parameters.To be able to simulate the overprints with TC ink just by CMY combination, simple colorimetric Neugebauer model, simple spectral Neugebaur model, and also their Yule-Nielsen modifications were used. By iteration techniques, fractional area coverage of CMY simulations was obtained. In second step, security patterns consisting of CMY combination with TC ink overprint and their computed simulation were printed and evaluated in terms of colour difference. For the study coated and uncoated p
