Sažetak
Credible and as accurate as possible reproduction along with the desire to achieve a print color that matches the original is one of the main requirements of the printing industry. An obstacle to meeting these requirements sometimes lies in the very way of measuring the imprint, that is, understanding the values obtained by spectrophotometric and densitometric measurements. Due to the interaction of light and matter (substrate and ink) there is an increase in the halftone element, the so-called dot gain. Typically, this increment is determined by the Murray- Davies algorithm, although it is well known the model neglects light scattering. The aim of the study is to compare the measured results obtained with a spectrophotometer using the Murray-Davies and the Yule-Nielsen model. The Yule-Nielsen model considers that substrate is not ideal and diffuse scattering of light occurs. Measurements performed using the Yule- Nielsen algorithm for different values of the parameter n deviate significantly from the data obtained by the Murray-Davies algorithm.
