The modern multimedia environment requires a growing number of innovative design solutions. At the same time, those solutions cause a number of difficulties during the reproduction processes, which are reflected in an unwanted shift in the manifestation of colours. The stated difficulties and unwanted shifts in the manifestation of colours are largely caused by the effects of induction and crispening that cause a shift in the manifestation of the colour of a certain stimulus. Within the research, an analysis of the intensity of the background effects of simultaneous contrast and crispening was carried out through the process of the adjustment of the printing process, which is by its nature identical to the method of adjustment that is used as a technique when estimating the size of the stimulus or its shift. For the purposes of this research, test samples based on achromatic (desaturated and monochromatic) rectangular figures were created. They were reproduced on two different printing substrates. The value of the shift in the manifestation of colours in relation to the reference values are determined by the method of tuning according to the principle of the Stevens' scale of the production/estimation of the relation. As a technique of visual evaluation, simultaneous binocular harmonization was used. The intensities of the effects are presented through the calculations of statistical differences in the colour ΔE00, while the shift of colour is presented through the statistical differences of the perceptual attributes of colour - the change of lightness ΔL00 (achromatic and desaturated samples), the tone ΔH00, and chromaticity ΔC00 (desaturated samples). Based on the results obtained in the research, what is provided are the guidelines for the printing and design of graphic products in situations where a manifestation of background effects (simultaneous contrast and crispening) that could affect the qualitative parameters of graphic products is expected.
