  • Patent number: 11840074
    Abstract: A printing apparatus includes a printing unit discharging a plurality of different pigmented inks onto a transfer member and forming an ink image, a processing unit performing processing such that each of the pigmented inks applied on the transfer member forms a layer, and a transfer unit transferring the ink image from the transfer member onto the printing medium conveyed by the conveyance unit. The pigmented inks include cyan, magenta, yellow, and black inks as pigmented inks of four basic colors, and at least one pigmented ink different from the pigmented inks of basic colors. A first ink at least one of the pigmented inks of the basic colors is applied onto the transfer member after a second ink is applied. The second ink is the pigmented ink different from the pigmented inks of the basic colors and has a color material density lower than that of the first ink.

  • Patent number: 10726316
    Abstract: In conventional color shading (CS) processing for correcting color unevenness with high precision, even an image to preserve pure colors can be corrected to use inks of other colors. Color unevenness is more appropriately corrected to provide a favorable image by properly using pure color preservation information and pure color non-preservation information as color correction information for the CS processing.

  • Patent number: 9704074
    Abstract: An image processing apparatus has an acquisition unit configured to acquire first multi-valued data corresponding to a first colored ink to be precedently applied to a same area of the print medium, and second multi-valued data corresponding to a second colored ink to be applied to the print medium succeedingly to the first colored ink; and a quantization unit configured to convert the first multi-valued data to first quantized data designating printing or non-printing of dot using the first colored ink, and converts the second multi-valued data to second quantized data designating printing or non-printing of dot using the second colored data. The quantization unit quantizes the first multi-valued data and the second multi-valued data so as to, on the print medium, make dispersibility of dots to be printed based on the first quantized data higher than dispersibility of dots to be printed based on the second quantized data.
