  • Patent number: 9050819
    Abstract: When recording is performed using two different types of inks, the ink discharge order is controlled in a unit region on a recording medium so that the number of pixel regions in which an ink having a relatively high pH buffer capacity in a basic region is applied later is larger than the number of pixel regions in which an ink having a relatively low pH buffer capacity in a basic region is applied later.

  • Patent number: 9039157
    Abstract: 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.

  • Patent number: 9016825
    Abstract: When an image is printed with inks each containing a polymer emulsion and a film forming agent, the ejection of the inks is controlled so that the ink having a relatively low dynamic surface tension forms dots having a higher dot connectivity than the dots formed with the ink having a relatively high dynamic surface tension.

  • Patent number: 8789914
    Abstract: 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 ?1 of the first black ink determined by a maximum bubble pressure method for a lifetime of 100 ms and a dynamic surface tension ?2 of the second black ink determined by a maximum bubble pressure method for a lifetime of 100 ms satisfy relationships of condition (1) of ?1>?2, condition (2) of ?1??2?20 mN/m, condition (3) of 40 mN/m??1, and condition (4) of 34 mN/m??2.

  • Patent number: 8474936
    Abstract: 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.

  • Patent number: 8444240
    Abstract: Processing liquid is ejected by a scan which is as prior as possible to the ink if it is determined that the printing duty of the ink is relatively low. Furthermore, the processing liquid is ejected by a scan which is as posterior as possible to the ink if it is determined that the printing duty of the ink is relatively high. Accordingly, the change of the glossiness can be suppressed regardless of the change of the printing duty of the ink. At the same time, it becomes possible to adjust the glossiness with a minimum necessary amount of processing liquid since the glossiness is adjusted not by varying the amount of the processing liquid depending on the printing duty of the ink, but by varying the printing order.

  • Patent number: 8356871
    Abstract: An inkjet printing apparatus includes a print head that scans a same area of a printing medium plural times and ejects plural kinds of ink and a treatment liquid thereon to form an image, and an ejection data generating unit for generating ejection data for ejecting the plural kinds of ink and the treatment liquid to each predetermined area of the printing medium in a predetermined order from the print head. The plural kinds of ink are 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, and the ejection data generating unit generates the ejection data in such a manner as to eject the plural kinds of 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.
