Newly developed UV-curable inkjet technology for forming high quality image with high productivity

Abstract

We have developed a new and unique UV-curable inkjet technology for a sheet-fed inkjet digital press AccurioJet KM-1, which achieves offset like high quality image with high productivity; 3,000 sheets per hour. A number of AccurioJet KM-1 have already run in the production lines of customers, and have gained reputation as "Real Digitalization Pioneer" for commercial printing industry. The single-pass inkjet printing technology, one of the key technology for the high productivity, is still a big challenge for image processing. To avoid the dots coalescing, we developed a new ink formulation and curing process which can control the ink viscosity precisely in the print head and on the recording media. We also improved the technology which can control the gloss level of the image. Combining them, we succeeded to develop a printing system which achieves offset like high quality image with high productivity.
