Abstract: A recording apparatus includes a processing unit configured to convert acquired image information into dot data, and an image forming unit configured to form an image on a recording medium based on the image information converted into dot data by the processing unit, wherein the processing unit enlarges an image of the acquired image information to a size protruding into margins formed at both side ends of the recording medium, then converts the image information into dot data, and then, based on side end position information of the recording medium detected by the detection unit, processes the image information converted into dot data so that image formation is not performed on portions of the enlarged image protruding into the margins.

Abstract: An inkjet printing apparatus, an inkjet printing system and an inkjet printing method are provided in order to correct a print density at a joint (overlapped portion) of nozzle arrays of a print head. The print density at the joint (overlapped portion) of the nozzle arrays is corrected based on a positional deviation between two adjacent nozzle arrays of the print head.

Abstract: 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.

Abstract: An ink jet printing apparatus is provided which can produce an image in good condition without contaminating the interior of the printing apparatus or the back of the print medium if the “marginless printing” using an ink that tends to coagulate is performed. To that end, a step is provided which applies to the ink absorber the coagulation inhibiting liquid that inhibits a colorant contained in the ink from coagulating. This suppresses the coagulation of the colorant on the surface of the absorber, allowing the colorant to quickly soak into the absorber. Therefore, the colorant is prevented from depositing on the absorber surface, alleviating the problems associated with the colorant deposit.

Abstract: An inkjet recording apparatus efficiently recovers defective discharge while reducing the amount of waste ink, acquires position information of a defective discharge nozzle and, based on the position information, determines whether the defective discharge has been caused by a bubble or a dust particle, and selects an ink circulation mode or a wiping mode.

Abstract: Each of four areas of 2×2 in one pixel has four sub areas and the four sub areas correspond to four nozzle arrays A to D. In the sub area of each area, information showing what nozzle array is used for a print of the area is defined. The sub area filled in black shows performing therein a print of a dot using nozzles in the nozzle array corresponding to the sub area. In this way, the dot arrangement pattern has information showing the nozzle array to which nozzles used for printing an area belong, for each area. Therefore, without executing the particular data allocation processing such as mask processing, the allocation of the dot data to the plurality of nozzle arrays can be carried out with a simple arrangement.

The print density at the joint (overlapped portion) of the nozzle arrays is corrected based on a positional deviation between two adjacent nozzle arrays of the print head.

Abstract: 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.

Abstract: An ink jet recording apparatus includes a recording head including a plurality of recording elements for ejecting ink in accordance with image data, wherein an image is formed by carrying out a recording scan N times for the same image area on a recording material, where N is an integer not less than 1, and a setting unit for setting a value of N in accordance with information relating to a glossiness of the recording material.

Abstract: An ink jet printing method and apparatus are provided which, even when an ink containing a colorant with a coagulating property is applied to a glossy print medium; enable to keep the glossiness of the print medium from being degraded. For this purpose, when forming an image on a glossy print medium, a coagulation inhibiting liquid for inhibiting a coagulation of ink is applied to at least a part of an area on the print medium where the ink is applied. This suppresses the coagulation of ink on the print medium surface and assures a quick spreading and soaking of ink. As a result, the surface of the glossy print medium can be kept smooth, retaining its glossiness.

Abstract: The invention can discriminate, with accuracy and reliability, a variety of printing media such as plain paper, coated paper, glossy paper and OHP sheet. Preferably, light emitting devices and light receiving devices are employed to detect the fiber orientation and gloss-level in the printing media surface. Based on this detection result, the type of each printing medium is decided.

Abstract: 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.

Abstract: A recording method performs recording on a recording medium using a pigment ink and a reaction liquid that has a higher surface tension than that of the pigment ink and contains a polyvalent metal salt capable of agglomerating the pigment ink. The method includes the steps of applying the reaction liquid on the recording medium, and bringing the pigment ink into contact with a surface of the reaction liquid that is present on the recording medium so that a filmy agglomerate, composed of an agglomeration of pigment aggregates produced by contact between the reaction liquid and the pigment ink, is formed on the surface of the reaction liquid applied on the recording medium.

Abstract: 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.
