In the diploma thesis the influence of the printing technique on the colorimetric values and the color fastness of printed fractal drawings on different textile materials was investigated. Fractal drawings were first captured with an optical scanner in high quality and then the scanned originals were processed. The fractal drawings were then applied to cotton and cotton/elastane fabrics using digital printing and dry transfer printing techniques. The samples of the printed fabrics were analyzed calorimetrically by measuring the CIELAB color values and the Raster tone values. They were also tested for color fastness according to the valid standards of SIST EN ISO, i.e., rubbing, hot pressing, washing and artificial light. The results of the test showed that when the colors were measured, there were fewer differences in CIELAB values between the samples in the case of black and more pronounced in the case of red colour. Digitally printed samples have poor resistance to rubbing, ironing and artificial light, while the color fastness of printed samples to washing was superior, regardless of the printing technique used. From the results of the study, it can be concluded that both printing techniques have advantages and disadvantages for printing fractal drawings on the fabrics studied. The choice of suitable printing techniques depends mainly on the final use of the textile material.
