Sažetak
The term micro-uniformity, also known as graininess, has been borrowed from photography where it is defined as the character of a photographic image when it appears to be made up of distinguishable particles, or grains. Today this term is used more broadly to refer to small-scale non-uniformity. The goal of this paper was to find method for evaluation of graininess that is in correlation with method defined by standard ISO 13660:2001. Test target was printed on two different papers (coated and uncoated) using electrophotography. Graininess was quantified with two methods. First method was used in order to find reference values of graininess. For this purpose we used measurement device Personal IAS that integrates a high resolution digital microscope and a pocket size computer into a versatile high performance measurement instrument. This device works and calculates print quality attributes according to standard ISO 13660:2001. Second method is based on image analysis method which requires digitalization of prints. For digitalization we used scanner CanoScan5600F. Graininess was calculated using plug in for Matlab which works on the assessment of grayscale values of neighbouring pixels.
