Ink-jet recording apparatus

A printing apparatus includes a print execution section and a controller. The print execution section includes: a printing head having nozzles arranged in a first direction; a head driver that drives the printing head to discharge ink from the nozzles thereby forming dots on a printing medium; and a movement mechanism that moves the printing medium relative to the printing head in any of the first direction and a second direction intersecting with the first direction. The controller obtains a piece of object image data, generates, by using the object image data, a plurality of pieces of dot data indicating formation states of the dots for pixels, and prints a printing image by causing the print execution section to execute discharge of the ink and movement of the printing medium by use of the pieces of dot data.

Printing apparatus

When a specified image is recorded while ranging over a boundary between a first dot recording range and a second dot recording range, a controller of an image recording apparatus judges whether or not a predetermined condition is fulfilled, the predetermined condition including at least one of a first condition which relates to a duty and a second condition which relates to a positional deviation in a scanning direction of a landing position of a liquid. If the predetermined condition is fulfilled, the dot belonging to a correcting portion is formed by correcting discharge in which the liquid in a discharge amount smaller than a set discharge amount is discharged. If the predetermined condition is not fulfilled, the dot belonging to the correcting portion is formed by ordinary discharge in which the liquid in the set discharge amount is discharged.

A printing apparatus includes: a print execution section and a controller. The print execution section includes: a printing head having nozzles, an ink having a specified color being discharged from the nozzles; a head driver which drives the printing head to form dots having the specified color on a printing medium by discharging the ink having the specified color from the nozzles; and a movement mechanism which moves the printing medium relative to the printing head. The controller is configured to: obtain object image data; generate, by using the object image data, a plurality of pieces of dot data indicating formation states of the dots having the specified color, for a plurality of pixels; and print a printing image by causing the print execution section to execute discharge of the ink having the specified color and movement of the printing medium by use of the pieces of dot data.

Printing apparatus and medium storing computer program

A controller acquires image recording data for recording a plurality of passes; determines a first movement distance of a carriage for recording each of the plurality of passes; determines a non-usage ratio that is a ratio of a number of unused nozzles in a last pass of the plurality of passes to a total number of the plurality of nozzles arranged in a conveyance direction; determines a second movement distance in a particular pass which is recorded before the last pass, the second movement distance being a movement distance of the carriage assuming that the particular pass is recorded without using nozzles of a first ratio smaller than or equal to the non-usage ratio; and in response to determining that the second movement distance is shorter than the first movement distance, performs image recording of the particular pass without using the nozzles of the first ratio.

When an image recording apparatus records an specific image over a boundary between a first dot formation range where dots are to be formed in a preceding recording operation of two consecutive recording operations and a second dot formation range where dots are to be formed in a subsequent recording operation of the two consecutive recording operations, the apparatus sets, as a correction portion, an end portion in a scanning direction of a specific region including at least one of a first boundary region adjacent to the second dot formation range and a second boundary region adjacent to the first dot formation range in the specific image, and forms the dot placed at the correction portion by discharging liquid of a discharge amount smaller than the discharge amount set for a dot element corresponding to the dot from nozzles.
