Abstract

A printing control apparatus, which controls printing of a printing area including an overlapping area on which printing is performed through a plurality of scanning operations, includes a printing data generation section that generates sets of printing data each associated with a corresponding one of the plurality of scanning operations in the overlapping area on the basis of an image data targeted for printing. The printing data generation section performs correction in accordance with a color density of the overlapping area in the image data.

Claims

1. A printing control apparatus that controls printing of a printing area including an overlapping area on which printing is performed through a plurality of scanning operations, the printing control apparatus comprising:

a printing data generation section that generates sets of printing data each associated with a corresponding one of the plurality of scanning operations in the overlapping area on the basis of an image data targeted for printing,

wherein the printing data generation section performs correction in accordance with a color density of the overlapping area in the image data.

2. The printing control apparatus according to claim 1, wherein the printing data generation section performs correction in which an amount of an ink to be discharged is increased when a color density of the overlapping area in the image data is increased.

3. The printing control apparatus according to claim 2, wherein the printing data generation section performs correction in which an amount of an ink that is to be ejected in a scanning operation that has used smaller amount of ink than the other scanning operations, is preferentially increased.

4. The printing control apparatus according to claim 1, wherein the printing data generation section calculates an average color density of the overlapping area in the image data for each predetermined pixel unit and performs correction in accordance with the calculated average color density for each predetermined pixel unit.

5. The printing control apparatus according to claim 4, wherein, the printing data generation section increases the number of pixels in the predetermined pixel unit when a resolution of the image data is increased.

6. The printing control apparatus according to claim 1, wherein the printing data generation section performs correction in accordance with a color density of an area surrounding the overlapping area in the image data.

7. A printing control method for controlling printing of a printing area including an overlapping area on which printing is performed through a plurality of scanning operations, the printing control method comprising:

performing a correction process in accordance with a color density of the overlapping area in the image data when generating sets of printing data each associated with a corresponding one of the plurality of scanning operations in the overlapping area on the basis of an image data targeted for printing.

8. A printing control apparatus that controls printing of a printing area which is to be printed on a line-by-line basis and has an overlapping area on which printing is performed using a plurality of nozzles, the printing control apparatus comprising:

a printing data generation section that generates sets of printing data each associated with a corresponding one of the plurality of nozzles for the overlapping area on the basis of an image data targeted for printing,

wherein the printing data generation section performs correction in accordance with a color density of the overlapping area in the image data.
