Abstract:
Digital reproduction is spreading as to methods and application in many printing business areas in a new way: in graphics make ready, reproduction photography, production of printing forms, digital and conventional printing. Theory in the screening element and screening cell area is spreading to forms that have not been researched nor applied yet. The need for new screening systems is prominent in the security product applied production, large format design, and in new material use. Stochastic screening has yielded positive results in printing that integrates process and spot inks, improving thus the problems of moire and digital defining of screening cell coverage. There is need for finishing in the digital stochastic screening area because the coverage behavior in border areas has been leftwithout definition. Numerous issues in the ?dot gain?, transparency and digital printing application area have been opened. This paper will investigate the interconnection of the digital screening cell, multi-color covering of the image element area together with new screening element definition experimenting. Graphics to be applied in the area of high security should be individualized. The paper investigates imitations of hand-made lines known from times when images were designed with the help of graving techniques. Line graphics had the advancement of direction in accordance with drawing details. This paper will demonstrate the algorithm of constant screening element angle change according to parts marked in the image.
