Abstract
A full-overlap type recording apparatus includes a recording unit and a controller. In the recording unit, n pieces of recording heads are disposed in a main scanning direction, positions of the n pieces of recording heads are shifted from each other in a sub-scanning direction, and the n pieces of recording heads are disposed so as to form m sets in the sub-scanning direction. The controller determines a use head based on the image data, and the use head is a recording head used for forming dots on a recording medium. The controller determines the use head for all raster lines formed on the recording medium, so as to respectively use the n pieces of recording heads when the raster lines are formed.
Claims6
A recording apparatus which is a full-overlap type recording apparatus, the apparatus comprising:
- a recording unit which includes n pieces (n is a natural number of 2 or more) of recording heads which enable forming of dots on a recording medium and are disposed in a main scanning direction of the recording unit, the n pieces of recording heads being disposed so as to have positions shifted from each other in a sub-scanning direction of the recording unit, and the n pieces of recording heads being disposed so as to form m sets (m is a natural number of 1 or more) in the sub-scanning direction;
- a carriage that moves the recording units in the main scanning direction and the sub-scanning direction;
- and
- a controller that determines a use head based on image data, the use head being one of the recording heads, which is used for forming dots for one raster line on the recording medium,
- wherein
- the controller determines the use head for all raster lines formed on the recording medium, so as to respectively use the n pieces of recording heads when the raster lines are formed.
A recording method of forming dots on a recording medium by using a full-overlap method and by using a recording apparatus which includes a recording unit and a carriage, the recording unit including n pieces (n is a natural number of 2 or more) of recording heads which enable forming of dots on a recording medium and are disposed in a main scanning direction of the recording unit, the n pieces of recording heads being disposed so as to have positions shifted from each other in a sub-scanning direction of the recording unit, and the n pieces of recording heads being disposed so as to form m sets (m is a natural number of 1 or more) in the sub-scanning direction, and the carriage moving the recording units in the main scanning direction and the sub-scanning direction, the method comprising:
- determining a use head based on image data, the use head being one of the recording heads, which is used for forming dots for one raster line on the recording medium,
- wherein
- in the determining the use head, the use head is determined for all raster lines formed on the recording medium, so as to respectively use the n pieces of recording heads when all raster lines are formed.
