20080246791 | INKJET PRINTING APPARATUS AND INKJET PRINTING METHOD - One or more scans used to apply a specific ink are varied according to the overlapping conditions of the specific ink and a non-specific ink, and bias in the specific ink nozzle usage frequency and bias in the printing ratio among passes is suppressed. For this purpose, one or more scans used to apply the specific ink are determined on the basis of applying amount information for the specific ink and the non-specific ink. For example, the one or more scans used to apply the specific ink are determined such that the ratio of specific ink applied by the last half of plural scans is greater for a unit pixel whose application ratio of non-specific ink to specific ink is greater than a predetermined ratio than for a unit pixel whose application ratio of non-specific ink to the specific ink is less than the predetermined ratio. | 10-09-2008 |
20090073203 | INK JET PRINTING APPARATUS, INK JET PRINTING METHOD, AND DATA GENERATING APPARATUS - An ink jet printing apparatus, an ink jet printing method, and a data generating apparatus are provided in which an image performance such as an abrasion resistance can be improved and a printing head can have a longer life by ejecting processing liquid at an appropriate time. The processing liquid is ejected, to a predetermined area on a printing medium in which the formation of a image by ink is completed, from a printing head in two or more scannings in five scannings of the printing heads. | 03-19-2009 |
20090073204 | INK JET PRINTING APPARATUS, INK JET PRINTING METHOD, DATA GENERATING APPARATUS, COMPUTER PROGRAM, AND INK JET PRINTING SYSTEM - The present invention provides an ink jet printing apparatus, an ink jet printing method, a data generation apparatus, a computer program, and an ink jet printing system by which a timing for ejecting a processing liquid can be changed to improve image performance of a printed image such as abrasion resistance, to provide the printing head with a longer life, and to improve a throughput. The processing liquid is ejected to a predetermined area on a printing medium, for which a formation of an image by ink is completed, in two or more scannings among five scannings of the printing head. When an amount of ejection data for ejecting the processing liquid in the fifth scanning for ejecting only the processing liquid is equal to or lower than a predetermined amount, the fifth scanning is not carried out. | 03-19-2009 |
20090160885 | INKJET PRINTING APPARATUS AND INKJET PRINTING METHOD - Provided are an inkjet printing apparatus and an inkjet printing method in which a high-quality image free of peeling of an image face can be printed, while an amount of a treatment liquid consumed is reduced. For that purpose, a group of pigment-based inks excellent in wettability with respect to the treatment liquid (small in contact angle with respect to the treatment liquid) are made relatively small in a proportion of the treatment liquid applied to a position to which the pigment-based ink concerned is applied. In contrast, a group of pigment-based inks poor in wettability (great in contact angle with respect to the treatment liquid) are made relatively great in a proportion of the treatment liquid applied to a position to which the pigment-based ink concerned is applied. | 06-25-2009 |
20100328388 | INKJET PRINTER, INKJET PRINTING METHOD AND PROGRAM - The present invention ejects a treatment liquid at a scan before a scan where ink is ejected and reduces variations in a time interval from a point of the ejection of the treatment liquid to a point of the ejection of the ink, thereby enabling an increase in image performance, and longevity, low costs and reduction in size of the print head. For achieving this object, the present invention includes a treatment liquid ejection data generating unit configured to generate the treatment liquid ejection data for ejecting the treatment liquid from the print head to the unit area before the formation of the image by the ink starts. The treatment liquid ejection data generating unit generates the treatment liquid ejection data in such a manner as to eject the treatment liquid at the plural times of the scans of the print head. | 12-30-2010 |
20100328389 | INKJET PRINTER, INKJET PRINTING METHOD AND PROGRAM - The present invention has an object of providing an inkjet printing apparatus which can improve image performance while restricting an ink consumption amount of a treatment liquid. The present invention generates ejection data for ejecting the plural kinds of the ink and the treatment liquid to each predetermined area of a printing medium in a predetermined order from the print head. The plural kinds of the ink is classified in plurality based upon a minimum application amount of the treatment liquid per a predetermined area required for realizing an effect of the treatment liquid. Ejection data generating unit generates the ejection data in such a manner as to eject the plural kinds of the ink and the treatment liquid from the print head according to the order determined in accordance with the classification of the ink ejected within the predetermined area. | 12-30-2010 |
20120133691 | INK JET PRINTING APPARATUS, INK JET PRINTING METHOD, AND DATA GENERATING APPARATUS - An ink jet printing apparatus, an ink jet printing method, and a data generating apparatus are provided in which an image performance such as an abrasion resistance can be improved and a printing head can have a longer life by ejecting processing liquid at an appropriate time. The processing liquid is ejected, to a predetermined area on a printing medium in which the formation of a image by ink is completed, from a printing head in two or more scannings in five scannings of the printing heads. | 05-31-2012 |
20130155144 | INKJET RECORDING METHOD - An inkjet recording method includes applying a pigment-containing first black ink to a recording medium to record an edge region of an image, and applying a pigment-containing second black ink to the recording medium to record an inner region of the image. A dynamic surface tension γ | 06-20-2013 |
20130187971 | IMAGE PROCESSING METHOD AND IMAGE PROCESSING APPARATUS - There are provided an image processing apparatus and an image processing method which can shorten a drying time of inks in an edge region of an image, and can form a sharp image without bleeding of the ink applied onto the edge region into a blank paper. The image processing method generates applying data for forming an image on a print medium by a relative scan between print heads for ejecting a first ink and a second ink having the same color with the first ink and lower in surface tension than the first ink, and the print medium. The image processing method generates first data for applying the first ink to a predetermined region that is adjacent to an edge region of the image and that is included in an inside region inward of the edge region, and generates second data for applying the second ink to the edge region. | 07-25-2013 |
20140028766 | IMAGE RECORDING METHOD - The image recording method includes a first process of applying a first black ink containing a pigment to a record medium; and, after the first process, a second process of applying a second black ink containing a pigment to the record medium such that the second ink at least partly overlaps the first black ink, in which the first black ink contains a salt containing at least one kind of cation selected from the group consisting of an alkali metal ion, an ammonium ion, and an organic ammonium ion and at least one kind of anion, and the static surface tension of the first black ink is higher than the static surface tension of the second black ink. | 01-30-2014 |
