Procesne boje, svojim karakteristikama, znacajno uticu na kvalitet stampe. K valitet stampe, sam po sebi, predstavlja složen pojam, jer ukljucuje željenu reprodukciju boja kao i odgovarajucu reprodukciju elemenata slike. U radu su prikazana istraživanja uticaja pojedinacnih procesnih boja na parametre kvaliteta digitalno stampanih tekstilnih materijala razlicitog sirovinskog sastava. Istraživanje je obuhvatilo analizu osnovnih atributa kvaliteta stampe: makro neuniformnosti, reprodukciju linija i tacaka. Uzimajuci u obzir rezultate istra ž ivanja , može se zakljuciti dapojedine procesne boje svojimkarakteristikamaumnogomeuti c unakvalitet s tampe .Pri sagledavanju cjelokupnog kvaliteta otisaka ne može se vrsiti analiza parametara kvaliteta tekstilnihpodloga stampanih samo jednom bojom.

This paper presents results of experiment conducted in order to determine influence of mesh density on surface roughness of textile materials printed with screen printing technology. Experiment was conducted to prove hypothesis that printing with different mesh density of the screen will cause changes in surface roughness parameters. Density of the screen mesh is usually used for determining volume of the ink transfer to the substrate. Volume of the transfer ink has a significant influence on changes in surface roughness of substrates. Surface structures of the textile substrates are filled with ink thus causing changes in surface roughness. For these experiment three different types of screen printing mesh were used with variable mesh density, 46, 54, as well as 90 threads per centimeter. Printing substrates used in the experiment was textile material composed of 100 % cotton. Inks used for printing were cyan, magenta, yellow, black, and green. All together 15 samples were made and their surface roughness was measured using TR 200 measuring unit. Mean value of 10 measurements is presented and further analyzed. The results showed a correlation between the type of screen printing mesh used and changes in surface roughness.

which chromatic adapta - tion should be applied when a change of illumina - tion is introduced as well as which colour difference formula to use and how it should be weighted.

Printed textile materials are often exposed to certain external

In addition to printing techniques, there are various characteristics that affect the quality of printed products. Most frequently questioned features are line, dot, and text reproduction. In this paper it is investigated how different substrates, printed by the same printing technique, affect the quality parameters of printed samples. Print quality includes the process of obtaining the desired reproductions of color and image elements, important parameters of print quality are the quality of lines and dots, and the feature of the substrate that is significant for this work is the roughness of the substrate. This paper presents the testing of three different materials on to which the test form was printed by electrophotography, as a digital printing technique. The tests are based on analysis of line, dot and text reproduction, as well as analysis of the roughness of the substrate on samples printed in black. Based on the obtained results it can be concluded that the substrate affects the quality of printed products.
