ABSTRACT:
To reduce a calculation load upon banding reproduction, a printer driver transfers draw information sent from a GDI to a draw discriminating unit. The draw discriminating unit confirms that a filtering process which needs various background colors such as ROM process or α blending process is not included for the drawing images constructing an intermediate language. The printer driver transfers the draw information included in an area of one page to a drawing unit. The drawing unit issues a physical color converting request of color information included in the drawing image to a color converting unit. In response to the physical color converting request of the color information included in the drawing image issued from the drawing unit, the color converting unit transfers information of only a physical color component which is at present being processed from the color information included in the drawing image to the drawing unit.
