Disadvantages of Flags Colour Definition Using Subjective Evaluation System

The analyses in this paper were performed on the University of Zagreb flag, originally made from PES fabric, for which the legal regulation has been performed by the Faculty of Textile Technology. The primer evaluation has been performed according to Pantone, CMYK system and CIE objective evaluation system. The colour of the flag has been evaluated as the Pantone 19- 3952 TPX. In CMYK system the values were 85, 70, 6 and 0. The spectrophotometric colour parameters values were: h* (hue) 285, C* (chroma) 40 and L* (lightness) 31. After this analyze, using colour match prediction operation, the reproduction of the original colour was performed on PA and CV materials. Comparing the original fabric colour with one on PA and CV materials, the dE values were higher than 1, 5 for PA and higher of 2 for CV. As for the colour parameter difference, the most emphasized was hue parameter difference (dh*).
