ARTICLE ANNOTATION

quote
To study the influence of raster structure properties on the quality of color reproduction of images transformed by regular, stochastic and hybrid screening methods, colorimetric parameters and values of color differences were determined. For an objective assessment of the quality of color reproduction, prints were obtained on a Speedmaster CX-104 offset printing machine in the production conditions of ANIS POLIGRAF LLC in Tashkent (Uzbekistan). Along with monitoring the uniformity of paint supply, fluctuations in color characteristics across or along the printing direction were estimated. For this purpose, colorimetric measurements of prints were carried out, since they more accurately characterize color differences. It was found that when using regular, stochastic and hybrid screening methods, accurate color reproduction on prints is ensured, since the dot gain values ΔE up to 1, distortion of the size and shape of raster dots are minimal, the image is completely consistent with the original, which means that the printing equipment used accurately reproduced the specified colors.
