  • Patent number: 8941876
    Abstract: When image is formed by a liquid ejection head, input image data is subjected to conversion processing including tone conversion using a first look-up table (LUT) and density correction or non-uniformity correction in nozzle units using second LUTs. Ink use amount in image formation is predicted from reduced image data which is generated from the input image data. In this, the calculation is made more efficient by applying a third LUT which is compiled according to requirements from the second LUTs, to the reduced image data, rather than using the second LUTs directly. Since the image conversion processing is carried out which combines the first LUT for tone conversion and the third LUT corresponding to the non-uniformity correction, and the ink amount distribution data is calculated from the reduced image data after the conversion, then it is possible to ascertain an accurate ink amount which reflects the image adjustment conditions.

    Abstract: A method for performing color registration on template media having template markings thereon comprises sensing the template media using a sensor to obtain first image data; printing a test pattern on the template media; sensing the template media along with the test pattern printed thereon using the sensor to obtain second image data; determining an output image data of the test pattern from the first image data, the second image data, and an estimated image data of the template media with the test pattern printed thereon; determining process direction and cross-process direction misregistrations from the output image data; and adjusting printheads based on the process direction and the cross-process direction misregistrations to provide adjusted color registration on subsequent template media. The estimated image data is representative of light scatter from the test pattern and light absorption by the test pattern.

  • Patent number: 8643891
    Abstract: An image processing device includes a multi-layer data acquiring part configured to acquire multi-layer data having a required-formation-amount-related value representing a value relating to a formation amount required to form an image, and an expanding part configured to expand, based on a correspondence relationship for expansion, the acquired multi-layer data into multiple sets of single-layer data. The correspondence relationship for expansion has a correspondence relationship between the required-formation-amount-related value in each of the sets of single-layer data and the required-formation-amount-related value in the multi-layer data. The required-formation-amount-related value in the multi-layer data is image data that exceeds a maximum-formation-amount-related value representing a value relating to a maximum formation amount of a color value of the single-layer data with which an image can be printed in a single printing process.

  • Patent number: 8643899
    Abstract: A printed layer formation processing device performs a part of a process for forming a printed layer on a part of the print medium by a first colorant in a molded object formation process. The printed layer formation processing device includes: a formation amount correspondence relationship storage part that stores a formation amount correspondence relationship, which is a correspondence relationship between a degree of deformation of the print medium and a formation amount of the first colorant, which are correlated so that the thickness of the printed layer is substantially the same in respective regions of the molded object, a deformation degree acquisition part that acquires the degree of deformation in the respective regions of the print medium; and a formation amount determining part that determines the formation amount of the first colorant in the respective regions based on the degree of the deformation and the formation amount correspondence relationship.

  • Patent number: 8643898
    Abstract: A plurality of grid points for forming a quadrangle, and an internal point included within the quadrangle, are quasi-formed on a medium prior to deformation, and position information is acquired that relates to the positions of the quasi-formed grid points and internal point moved in conjunction with the deformation of the medium. A triangle deformation ratio is acquired from the areas of triangles formed by the grid points and internal point before and after deformation, and a discharge amount of ink formed on the medium is computed in accordance with the deformation ratio after deformation, with respect to the triangles before deformation.

  • Patent number: 8630017
    Abstract: An ink jet printing apparatus that improves the visibility of a character and its background in different colors or of outline characters is provided. Specifically, outline character bold data is inverted and each of the pixels in the data is expanded to adjacent eight pixels. Then, the expanded outline character is processed into expanded inverted data. The logical AND of the inverted expanded data and K data on a background image is then calculated to generate K data with the outline character expanded. This results in an image with the outline character expanded. That is, the present invention enables characters with improved visibility and free from blurredness to be printed while preventing the adverse effect of bleeding on the outline character.
