Abstract
A printing method and a printing apparatus of the present invention are capable of performing both a vertical registration adjustment in which a range of nozzles used for printing is limited and a vertical registration adjustment in which print data is shifted. More specifically, switching is performed between the vertical registration adjustment in which a range of nozzles used for printing is limited and the vertical registration adjustment in which print data is shifted, in accordance with conditions such as a printing mode, types of printing medium, and the like. Thereby, an improvement of a throughput by a printing apparatus and an improvement of an image quality printed by the printing apparatus can be together achieved.
Claims15
A printing method for printing by performing scanning of a print head provided with a plurality of printing element groups in a scan direction, each of which arranges a plurality of printing elements in a direction intersecting with the scan direction, said method capable of performing:
- a first printing position adjustment that adjusts printing positions in a arrangement direction of the printing elements between the plurality of printing element groups, in the first printing position adjustment, printing elements used for printing being limited for each of printing element groups in accordance with deviation amounts of the printing positions between the plurality of printing element groups, or
- a second printing position adjustment that adjusts printing positions in a arrangement direction of the printing elements between the plurality of printing element groups, in the second printing position adjustment, print data corresponding to the printing element group is shifted for each of printing element groups in accordance with deviation amounts of the printing positions between the plurality of printing element groups.
A printing apparatus for printing by performing scanning of a print head provided with a plurality of printing element groups in a scan direction, each of which arranges a plurality of printing elements in a direction intersecting with the scan direction, said apparatus capable of performing:
- a first printing position adjustment that adjusts printing positions in a arrangement direction of the printing elements between the plurality of printing element groups, in the first printing position adjustment, printing elements used for printing being limited for each of printing element groups in accordance with deviation amounts of the printing positions between the plurality of printing element groups, or
- a second printing position adjustment that adjusts printing positions in a arrangement direction of the printing elements between the plurality of printing element groups, in the second printing position adjustment, print data corresponding to the printing element group is shifted for each of printing element groups in accordance with deviation amounts of the printing positions between the plurality of printing element groups.
A program that is read by a computer to cause the computer to function as a control apparatus for a process of generating print data for printing, said function comprising the step of performing:
- a first process of performing a printing position adjustment process adjusting printing positions in a arrangement direction of printing elements between a plurality of printing element groups in a print head, in which process printing elements used for printing are limited for each of printing element groups in accordance with deviation amounts of printing positions between the plurality of printing element groups, and image processing executed for each scanning area of the print head, in this order, or
- a second process of performing a printing position adjustment process adjusting printing positions in a arrangement direction of the printing elements between the plurality of printing element groups, in which process print data corresponding to the printing element group is shifted for each of printing element groups in accordance with deviation amounts of the printing positions between the plurality of printing element groups, and image processing executed for each scanning area of the print head, in this order.
