| Abstrakt: | SUMMARIES.Imaging photometry, the new modern method of evaluation of the quality of print is discussed in the following article. Authors explain preparation of reproducible image structures; correction of the images (e.g. thermal noise, non-homogeneity of illumination, gamma correction) and main attention is aimed to the evaluation of quality of prints (different grades of paper) and the evaluation of printed areas with regard to used printing technology. CONCLUSION. The article examines possibilities of use of the fractal analysis for evaluation of the quality of printed material and printed areas. The main requirement for analysis is to obtain high quality digital images of prints prior to analysis. It is also of great importance to ensure minimal loading of digital records with some common recording errors. It has been confirmed that results of such analysis forms base for objective comparison of papers homogeneity as well as for comparison of print colour homogeneity for full area print. The other very important area of use of fractal analysis of printed structures is comparison of quality of reproduction of the print points. Last couple of paragraphs tries to briefly introduce use of fractal analysis for evaluation of the colour separation for example for offset print technology.
