  • Publication number: 20240025184
    Abstract: The invention is directed to a printing apparatus and a printing method for executing so-called back printing. A white image and an non-white image are printed to be superimposed on a transparent sheet-like printing medium. In the invention, at least one of the white ink amount constituting the white image and a non-white ink amount constituting the non-white image is adjusted according to the permeability information relating to the permeability. That is, the printed matter taking the permeability of the printing medium into account is obtained. As a result, an influence by the permeability of the printing medium is suppressed and a high-quality printed matter is obtained in sol-called back printing.

  • Patent number: 9189716
    Abstract: An image obtained by shrinking an original image in a row direction is halftoned, and this halftone dot image is enlarged in the row direction and recorded at double speed. In order to determine a threshold value of a threshold matrix used for halftoning an image, prepared is a matrix space in accordance with writing positions used for actual recording of an image. In the matrix space, writing elements are set alternately with non-writing elements both in the row direction and in a column direction. In the matrix space, turn-on numbers are allocated to all the writing elements in avoidance of the non-writing elements. Then, in accordance with the turn-on numbers, respective threshold values for the writing elements are determined. By shrinking the threshold matrix in the row direction with omission of the non-writing elements, a threshold matrix for double speed is obtained.

  • Patent number: 9124842
    Abstract: An image recording apparatus 1 generates halftone image data regarding black, cyan, magenta, and yellow from a multi-tone color image. Magenta is a target color component that has a lower ink density than that of the other color components. In generating halftone image data regarding magenta, the sum of the sizes of black, cyan, and magenta dots formed at a target pixel position is made smaller than or equal to a threshold dot size. If the hue of the pixel of interest is within a hue range in which magenta coloration is strong, it is determined that the threshold dot size is a corrected threshold dot size larger than the reference threshold dot size. It is thus possible to suppress overlapping of dots of a plurality of color components and to thereby improve color reproduction of the target color component while suppressing poor color reproduction and cockling.

  • Patent number: 9102165
    Abstract: In an image recording apparatus, only small ink droplets are ejected toward a recording medium in the range of tone values less than a second tone value. In the range of tone values greater than or equal to the second tone value and less than a first tone value, large and small droplets are ejected toward the recording medium. The first tone value is less than or equal to a 50% tone value, and the total ejection rate at the first tone value is less than 50%. In the range of tone values greater than or equal to the first tone value, only large droplets are ejected toward the recording medium. Thus, the occurrence of streaking can be suppressed while reducing the degree of instability of the landing positions of fine droplets of ink.

  • Patent number: 9007651
    Abstract: In the generation of a threshold matrix for Nx speed writing, first and second areas are set, the first area being a cluster of a plurality of first partial areas substantially evenly distributed in a matrix space, and the second area being an area of the matrix space excluding the first area. Next, at least two writing elements in each of the first partial areas are allocated occurrence numbers and changed into determined elements. Then, at least one writing element in the second area is allocated an occurrence number and changed into a determined element. Thereafter, the other writing elements are allocated occurrence numbers and changed into determined elements. In accordance with the occurrence numbers, the threshold value of each writing element is determined to obtain a threshold matrix for Nx speed writing. This results in a reduction in the graininess of an image in a highlight area.
