Print mottle is a common print defect, so the evaluation of this print parameter is vital in print quality assessment. The aim of this research is print mottle estimation, i.e. solid-tone surface uniformity assessment of different billboard materials, printed using ink jet technology. A GLCM image processing method was used as a tool for print mottle determination, as it proved to be good surface roughness as well as print mottle estimator. The main idea was to apply GLCM image processing method on ink jet printed samples that possess print mottle defects, and to test if this method can produce reliable estimations of this negative print effects. After obtaining quantitative results of print mottle level for each sample, all of them, according to appropriate color, were subsequently visually compared, in order to gain qualitative information about its solid-tone uniformity and establish which substrate material is superior in terms of solid-tone surface uniformity, as well as to verify previously obtained quantitative results and conclusions.

Printed textile materials are often exposed to certain external impacts. One of the most common impact, these materials are subjected to, is thermal load. This effect causes certain changes in textile fibers as well as changes of ink colour reproduction printed on these materials. In this paper is presented an investigation of the series of thermal loads effects on print quality parameters of digitally produced impressions on textile substrates. The research includes basic print quality attributes: colour reproduction, macro non-uniformity and quality of line reproduction. Investigation results indicate that by increasing number of thermal loads, bigger changes in colour reproduction occur. Also, the influence of the series of thermal loads on mottle and line reproduction variations is confirmed, as well as the influence of printing substrate characteristics on print quality.

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. Zakljuceno je da na kvalitet stampe utice i podloga svojim sirovinskim sastavom.
