Sažetak
The research focused on the study of typographic and colorimetric properties of prints on transfer foils made with the non-impact printing technology, using two different printers – electrophotography- and inkjet-based, their cartridges and two thermal transfer materials which were transferred onto a cotton fabric. Four-colour prints and typography defined with three different typefaces (one sans-serif, one transitional and one modern) were made. The typefaces were tested in four sizes (6, 8, 10 and 12 pt). The prints were exposed to a different number of washing and drying cycles, the differences in colour and typographic tonal density being measured before and after the cycles. The colour differences of 100% and 50% intensity fields (CMYK100 and CYK50)were measured spectrophotometrically, whereas the difference in typographic tonal density was measured by means of image analysis. The differences in colour ΔE00, lightness ΔL00, chromaticity ΔC00 and hue ΔH00 for the substrate and prints(CMYK) after a different number of washes were calculated with the obtained spectrophotometric measurements. The changes in the colour of the substrate alone had to be taken into account as well, as these results demonstrate that the hue of the transferred layer of the transfer foil also influences the indirect transfer printing. While inkjet printers apply a thicker layer of ink, more precise printing of smaller graphic elements is achieved with electrophotography. The most substantial difference in typographic tonal density after a different number of washes was measured at smaller type sizes (6 in 8 pt). Due to its design features, the tested sans-serif typeface displayed higher typographic tonal density than the other two tested typefaces. After a different number of washes, the highest difference in typographic tonal density was measured at the sans-serif typeface.
