摘要： An ink jet printing apparatus is provided in which ink absorbers, capable of performing their function to the fullest extent to quickly absorb an ink that tends to coagulate, are installed to prevent an interior of the printing apparatus and the back of a print medium from being contaminated. To this end, the printing apparatus has an ink absorber that contains a coagulation inhibitor capable of inhibiting the coagulation of colorant contained in the ink. This arrangement inhibits the coagulation of the colorant on the surface or in the interior of the absorber, allowing the colorant to be absorbed quickly and uniformly into the interior of the absorber. Therefore, problems caused by a deposition of the colorant on the surface of the absorber or by a degraded absorbing capability can be alleviated, thus keeping the image output in good condition.

摘要： An ink jet printing apparatus can prevent or suppress the generation, by a reaction liquid and ink, of a reaction product on the face surface of a discharge head, and can remove the ink, the reaction liquid or the reaction product adhering to the face surface so as to constantly maintain a stable printing quality. Immediately before a printing operation is initiated, an anti-coagulation liquid is sprayed on the face surface of a discharge head, and the discharge head performs the discharge operation (printing operation) with the anti-coagulation liquid applied to the face surface. When the printing operation has been completed, or when the printing of a predetermined amount of data has been performed, the face surface of the discharge head is wiped by blades to remove the ink and the reaction liquid. Since the anti-coagulation liquid is applied to the face surface in advance, the generation of the reaction product on the face surface is prevented or suppressed. Furthermore, even when a reaction product is adhered to the face surface, the coagulation of this product on the face surface can be prevented.

摘要： A printing apparatus includes a plurality of full-line type printheads. The printing apparatus holds information relating to overlap nozzles that overlap between a reference printhead and an adjustment printhead, generates discharge data for causing a tilt adjustment pattern to be printed by nozzles disposed in different positions in the overlap nozzles that overlap between the reference printhead and the adjustment printhead, and causes ink to be discharged from the nozzles in the overlap nozzles that overlap between the reference printhead and the adjustment printhead based on the discharge data. In this manner, the tilt adjustment pattern is printed on a printing medium.

摘要： An ink jet printing apparatus and method are provided which can satisfy in a well-balanced manner both an improvement of image uniformity and a reduction in glossiness variations. A plurality of print modes are prepared which include: a first print mode to perform a printing operation in a way that makes equal print ratios of the plurality of nozzle arrays; and a second print mode to perform a printing operation in a way that makes a print ratio of at least one of nozzle arrays situated at ends of the plurality of nozzle arrays smaller than print ratios of other nozzle arrays. The user selects from the plurality of print modes an appropriate one that strikes a balance between uniformity and glossiness and thereby can achieve a desired quality of image.
