20090015611 | INK JET PRINTING SYSTEM AND INK JET PRINTING METHOD - An image data signal value conversion is performed such that the volume of ink applied to image areas on a print medium to be printed by the overlapping portions of the printing element substrates is smaller than that applied to image areas on the print medium to be printed by other than the overlapping portions. Alternatively, the image data signal value conversion is performed such that the volume of ink applied to overlapping areas on the print medium to be printed by two consecutive printing main scans is smaller than that applied to other than the overlapping areas. For this reason, even when forming photographic images by using an elongate “joining head”, high-quality images with no density unevenness between overlapping areas and other areas on a print medium can be produced. Also in a serial type printing apparatus, uniform images with no seam stripes can be produced. | 01-15-2009 |
20090040550 | DATA GENERATION APPARATUS, PRINTING APPARATUS AND DATA GENERATION METHOD - When a feeding amount for multi-pass printing is changed, the purpose related to an image quality using a binary data generation pattern can still be attained by, for example, a density pattern method. Specifically, a multi-pass printing mode is identified, and a density pattern selection matrix associated with a cycle of binary data generation is selected in accordance with the selected printing mode. That is, a density pattern selection matrix employed for binary data generation using a density pattern is changed to a size corresponding to the feeding amount designated by the selected printing mode.

20100045723 | INK-JET PRINTING APPARATUS AND INK-JET PRINTING METHOD - The print permitting ratios of the masks in the first to fourth passes of a C ink are respectively 6.2%, 37.5%, 37.5%, and 18.8%. On the other hand, the print permitting ratios of the masks in the first to fourth passes of an M ink are respectively 12.5%, 37.5%, 37.5%, and 12.5%. In this way, the respective masks are set such that a larger amount of the C ink is applied in a later pass as compared with the M ink. Thereby, it is possible to reduce an amount of the M ink to be applied later with respect to the C ink functioning to “reduce a permeation speed of an ink applied later by filling,” and it is possible to prevent a permeation speed from slowing down overall. As a result, it is possible to prevent the occurrence of beading due to a time to complete permeation becoming longer. | 02-25-2010 |
