  • Patent number: 7997717
    Abstract: The invention allows an image printing on a wide range of print media regardless of how much ink the print media absorb, without sacrificing a high printing flexibility of an ink jet printing system. To this end, the image forming method of this invention includes: a process of modifying a surface of an intermediate transfer body by applying energy to the surface; a process of ejecting ink onto the surface-modified intermediate transfer body by using an ink jet printing device; and a process of transferring ink from the intermediate transfer body to a print medium. With this invention, therefore, an ink image can be formed on the intermediate transfer body having a surface layer, without causing bleeding or beading, and then transferred onto the print medium in good condition.

  • Publication number: 20110032422
    Abstract: In a video processing system which divides HD-size image data into a plurality pieces of sub-image data and performs image processing for upconversion to 4K×2K image data, four image processors synchronous with an HD signal each process a corresponding one of the four pieces of sub-image data. In this case, the image processors process the four pieces of sub-image regions while causing the four pieces of sub-image regions to overlap at their division boundaries, and particularly process the overlapping regions during respective blanking periods. After the image processing of the image processors, the overlapping data is removed. Thereafter, the pieces of image data of the four sub-regions are combined. Therefore, the division boundaries of the pieces of sub-images can be processed without a degradation in image quality.

  • Patent number: 7661809
    Abstract: A method and apparatus for forming an image which can form a high-quality image on a great variety of print media regardless of the surface roughness or ink absorptivity of the print medium, without sacrificing the high degree of freedom of the ink jet printing system are provided. An ink jet printing section ejects ink to an intermediate transfer body to form an ink image on the intermediate transfer body. Before the ink image thus obtained is transferred to a print medium, an ink transfer adjuvant is applied to the print medium. Then, the ink image formed on the intermediate transfer body is transferred to the print medium to which the ink transfer adjuvant has been applied.

  • Publication number: 20090027473
    Abstract: In the image-recording of an intermediate transfer system applying an ink jet recording method, reactive liquid reactable with ink is properly formed on the intermediate transfer body. By using the intermediate transfer body having a pattern consisting of lyophilic and lyophobic sections on a surface thereof, the reactive liquid is uniformly applied to the intermediate transfer body to form a layer having a suitable thickness. Thereby, it is possible to form an ink image on the intermediate transfer body while preventing the miss landing of ink droplets and restricting the deformation of an ink dots. By transferring this ink image to a recording medium, it is possible to form a high-quality ink image on various kinds of recording media in a stable manner.
