Application of the New Hybrid Screen Dot in Inkjet Plate-Making Technology

摘要

According to the characteristics of inkjet plate-making technology, the development and application of new hybrid screen dot is aimed to improve the quality of the inkjet plate and the reliability of inkjet plate-making technology. First, theoretically we prove the mechanism why the new hybrid screen dot can eliminate the inherent limitations of the inkjet technology, then compared to analysis the plate image effects between the hybrid screen dot and Amplitude Modulated (AM) screen dot which is outputted in the same print mode. The experimental results show that the hybrid screen dot significantly improves the image quality in the plate. The application of new hybrid screen dot not only reduces the human visual sensitivity when droplet deviations occur, but also breaks the frequency of each horizontal line in some degree, thus effectively improves the quality of the inkjet plate.
