Special Screening Technologies for Digital Flexo Imaging

Abstract

Thanks to recent developments of digital plate and laser imaging technologies, quality of flexography has been improved significantly. However, appropriate control of unique behavior and characteristics of flexo printing remain to be a major challenge in achieving superior print results. One of the important aspects of flexo process that determines final print quality is to control the ink behavior in highlight and shadow areas. Recent development of special screening technologies, such as "Groovy Screens", is to achieve better transfer and even distribution of ink at shadow and solid areas, and "Perfect Highlight" screening which helps to prevent undesirable highlight breaks and excessive dot from gaining drastically improve visual print quality of shadow and highlight area. I believe implementation of these screening technologies can be a significant contribution for development of new level of flexo printing value in Japan.
