This final work will examine the quality of the press, Croatian and European, depending on the bit-mapping techniques. Detailed analysis of the prints will determine whether it comes to the deformation of the screen elements, which is directly linked to the quality of printing. Thus it will be shown how to spot mentioned phenomena and the causes of formation. In the theoretical part there are listed types of screening, where each of them is explained in detail. Also, deformation of the screen elements is further explained as well as the most important parameters that reduce print quality. Experimental part is the practical part of this work. It describes the workflow and the measuring devices and equipment that were used. Then the results are being attached and analyzed and ultimately it comes to the conclusion. The test found which screening methods are used for specific printed matter, if it comes to dot gain or deformation of the screen elements, and at the very end it is determined whether there is a difference in quality (depending on the specified parameters) between the Croatian and European press.
