  • Publication number: 20230419065
    Abstract: The inkjet printing apparatus is configured to be able to execute a batch adjustment process of performing a plurality of times of adjustment processes related to printing in succession based on one instruction from an outside. The conveyance control unit maintains the conveyance speed at a first speed in a period when a chart printing process is performed and a period when a chart imaging process is performed. The conveyance control unit decreases the conveyance speed from the first speed to the second speed after the end of the chart imaging process in an adjustment process except for an adjustment process that is performed last in the batch adjustment process, and increases the conveyance speed from the second speed to the first speed before the start of the chart printing process in an adjustment process that is performed next.

  • Patent number: 10479102
    Abstract: After obtaining printing data, a user is allowed to specify regions whose amounts of ink consumed are estimated using high-resolution images, by which two regions (high-resolution estimation areas and low-resolution estimation areas) are set in a printing region. Thereafter, the amounts of ink (first amounts of ink) consumed are estimated using the high-resolution images regarding the regions set as the high-resolution estimation areas, and the amounts of ink (second amounts of ink) consumed are estimated using low-resolution images regarding the regions set as the low-resolution estimation areas. Finally, the total amount of ink consumed by printing is calculated from the first amounts of ink and the second amounts of ink.

  • Patent number: 10261735
    Abstract: After obtaining a print job (step S10), adjustment data is obtained based on job information included in the print job (step S20). After determining an estimation range (step S30), image data to be printed is corrected using the adjustment data (step S40). Then, an amount of ink which is predicted to be consumed by printing of an image represented by the corrected image data is calculated (step S50). Furthermore, when flushing is performed, an amount of ink which is predicted to be consumed by flushing is calculated (step S70).

  • Patent number: 10194057
    Abstract: A method for limiting the amount of ink discharged in a photocurable inkjet printing apparatus includes a conversion step of converting, an input grayscale value to the amount of ink; and a limit value setting step of setting, a limit value of the amount of ink discharged, for each of a secondary color not including a K color component, a tertiary color not including a K color component, and a color including a K color component. In the limit value setting step, the limit value for the tertiary color not including a K color component is set to a smaller value than the limit value for the secondary color not including a K color component, and the limit value for the color including a K color component is set to a smaller value than the limit value for the secondary color not including a K color component.

  • Patent number: 9403373
    Abstract: In printing image data for printing a color chart with a printing machine, instead of using a TAC value which is a total of CMYK values given to one pixel as a limit of ink amount supplied to a printing medium as done conventionally, creation of a color chart having a large color gamut is realized by considering and adjusting the amount of inks per unit area actually consumed at the time of printing and drying performance of each ink.
