Статья. - Опубликована в Printing Technology SPb’ №06 - сборник науч. тр. междун. науч.-техн. - 6 c.To the contrary to previous manual engraving, the fine detail and contour of an image are for over a century destroyed by the halftone dots involved by autotypie principle invention. Definition of the modern halftone images stays about ten times lower of printing process resolution. The adaptive screening technology was proposed and developed to overcome these shortcomings and eternal trade offs of halftoning. Based on Human Vision System (HVS) properties the adaptive screening process dynamically, over an image area, mutually exchanges the potentialities of printing in relation of tone rendition and fine detail quality with taking into account the local image area content.
This paper discusses some issues of practical application of this novel screening process to the traditional and digital printing technologies. Effects of an image quality improvement and variants of adaptive halftoning operation within the modern pre-press workflow are also observed.
