Development of the 23”×29.5” Sheet-fed Inkjet Press KM-1

Abstract

To materialize the “digital print,” we have been developing a new digital printing system with our inkjet technology. We adopted so called “single pass printing system” for the system. It has a page-wide print head array and can print ink droplets on a rapid-delivered paper. We developed a variety of technologies such as a new print head, a new ink, a new image compensation technique, and so on, for the system. We integrated 1,800 printing nozzles into 600 npi density that can eject small droplets in higher frequency. We developed a new ink formulation that can show performances necessary for the single pass printing. We also developed a new technique that can compensate streaky image defects. Combined these new technologies, we achieved to develop a new digital printing system that can print a highresolution and high-quality image quickly.
