Sažetak
The appearance of Moiré pattern can significantly affect the quality of offset reproduction. It is formed by superimposingof fine details of two or more structures.It appears in printing when: screen structures are misaligned because of misregistration (it is very difficult to predict it, because it is not visible on the proof), inappropriate combination of screen frequency and screen angles is used, an original halftone that contains patterned objects is scanned and exposed or when fine details of continuous tone original are superimposed whit input frequency of scanner or with CCD element structure of digital camera. The aim of this work is to investigate the influence of reproduction parameters, such as screen frequency, imaging resolution, register accuracy or input bit-map resolution to appearance of Moiré pattern. Tests will be done on a limited number of combinations of screen frequencies and input resolutions. The test result will be recommendations, which parameters combination should be avoided and which to use so that Moiré pattern could be minimized on the final printing product. Key words: Moiré, quality, reproduction, screening
