Sažetak
Thermochromic printing inks change their colour under the influence of temperature. Accordingly, their measurement is challenging. So far there were no attempts of measuring the reproduction quality of the thermochromic printed lines, rather the research was directed towards colour characterization and ink stability in terms of exposure to different degradation processes. The use of thermochromic colours adds value to the product, both through its attractiveness and the information it can convey to the consumer. Therefore, it is necessary to quantitatively characterize the prints. The line is the essential object on which any design is based. Accordingly, the quality of the printed line indicates the possibility of printing fine details with thermochromic inks. In this research, novel method of characterizing thermochromic line prints is presented. Prints were made by offset printing, by applying thermochromic UV ink on commercial offset paper. Applied ink is blue below 29°C, and colourless above the specified temperature. The printed line samples were measured at 20°C, and 40°C. Cooling and heating were controlled by placing the samples on the thermostatically controlled cover water block (EK Water Blocks, EKWB d.o.o. Slovenia). Quantitative analysis of the reproduced lines was performed using Personal IAS Imaging Device (Quality Engineering Associates Inc) and ImageJ (Laboratory for Optical and Computational Instrumentation) image processing software.
