摘要： An ink-jet printed product is formed by printing an image with a plurality of similar color inks having different concentrations and a special ink having a single concentration. In the product, graininess resulting from ink dots is decreased for all hues of the printed image. A decision is made as to whether or not a hue of an image to be printed can be printed with inks without the special ink of a color (for example, special color BL (blue)) having a single concentration. When it is decided that the hue of the image is to be printed with inks without the special color ink, data on ink color BL (blue) is decomposed into data on C (cyan) and data on M (magenta). The hue can be printed without the color BL, thereby significantly decreasing graininess in a portion having this hue.

摘要： An ink jet printing apparatus for industrial use, which is provided with a comparatively large number of nozzles arranged for high duty recording, particularly an ink jet textile printing apparatus, and an ink jet printing apparatus suitably used for printing on a large-sized medium, are provided together with a method for controlling the temperature of the printing head of such high duty printing apparatuses, and various other types of printing apparatuses reliably. To the large number of heaters used for recording in a printing step, driving signals are applied to cause them to discharge ink for recording and, to the discharge heaters that are not to perform recording, secondary driving signals that do not allow ink to discharge are applied. These secondary driving signals cause the heaters not used in recording to generate heat, so as to reduce unevenness in the intensities of heat generation among the many discharge heaters of the printing head. At the same time, cooling water is supplied by a cooling device to a cooling liquid path arranged for the printing head in order to cool it.

摘要： A serial type ink jet printing apparatus for textile printing sets a print beginning position and a print ending position so that the space between the print beginning position and the print ending position is wider than the textile printing medium. When the printing operation is performed, a small amount of ink is discharged from an ink jet head onto a textile support member before the head reaches the textile printing medium, by which ink with high viscosity can be exhausted in a continuous printing operation before printing on the textile. Therefore, the textile can be efficiently printed entirely from edge to edge with high quality, and a separate ink receiver for receiving the preliminarily discharged ink is rendered unnecessary.

摘要： An image recording apparatus using a plurality of recording heads that can prevent black lines from occurring at scanning boundaries of the recording heads. The total recorded ink volume at the boundaries is positively reduced so that the black lines and the overflow of ink are prevented. The apparatus includes at least a pair of a dark head for discharging relatively dark ink and a light head for discharging relatively light ink. The apparatus separates an input image signal into image signals applied to the dark and light heads using at least two tables. The two tables, one for edge nozzles of each recording head and the other for the remaining nozzles, separate the input image signal independently so that the total ink volume discharged from the edge nozzles are limited to a relatively small amount. Further, the total volume of ink discharged from the edge nozzles of the recording heads are positively reduced by performing black abstraction processing, UCR processing and black inking processing on the basis of the image signals after the separation by the tables, which image signals linearly correspond to the ink volume.

摘要： An apparatus for transmission, reception and recording of an image, such as a facsimile apparatus, capable of correcting the unevenness in density or improper density resulting from fluctuation in the performance of the recording head of the receiving unit, with a limited amount of data transfer. At the start of communication, correction data for uneven or improper density of the recording head are sent from the receiving unit to the transmitting unit. The transmitting unit corrects the multi-value image data to be transmitted, based on the received correction data, and sends the corrected image data after conversion into binary state. The receiving unit receives the binary image data and effects image recording. The time and cost for data transmission can be reduced, as the correction is conducted at the transmitting unit and the data transmission can be made in binary data.
