Reproduction objectivity in printing depends on a series of parameters. Primarily it is necessary to group the originals, based on the formal characteristics. In regard to the technological systems of taking the photographs, kinds of substrates and printing techniques used in reproduction process, it is necessary to determine the parameter dependence, which will enable the least reproduction deviation in regard to the original. Following parameters have been investigated in the thesis: originals, technological systems of taking photographs, substrates and printing techniques. The investigation was based on visual evaluation of the observer and on instrumental measurements. The data obtained by measurements are presented in CIELAB colour system. Based on the calculated values of the colour difference, by the expressions ΔE*94 and ΔE00, and colour reproduction curves, the colour deviation obtained by instrumental measurements was connected with the deviation obtained by visual evaluation of the observer. Based on the obtained data, the optimal start conditions and reproduction process for each group of originals was suggested, which enable obtaining of objective reproduction in printing.
