We have developed a single-pass inkjet digital press AccurioJet KM-1, which can achieve off-set like high image quality with high productivity, 3,000 sheets per hour. To success in the commercial printing field, high image quality and high consistency are required to be achieved. For achieving high image quality, undesirable image defect such as banding should be improved. Therefore we have classified image banding into two, narrow banding (streak) and wide banding. To solve the narrow banding issue, we developed a unique halftoning and a nozzle compensation techniques by means of image simulation process. We also improved the wide banding issue by adjusting the dot size and the dot density. As for the high consistency, we developed a streak F detection system, which scans images on every sheet, checks the existence of streaks, and feeds the results back to the image compensation systems.
