ABSTRACT:
In a case where an image region to be processing in RGB color space and an image region to be processed in YMCK color space are mixed, if objects converted from RGB representation to YMCK representation are re-converted to RGB representation and RGB rendering is performed, the load on the system is increased, and the throughput of a printing apparatus is degraded. Accordingly, bands to be processed in the RGB color space are separated from print information inputted from a host computer, and pre-rendering is performed on the separated bands. Thereafter, bands to be processed in the YMCK color space are rendered by a rendering processing execution unit. The output order of the data of the respective bands pre-rendered in the RGB color space and that of the other bands are adjusted, and the data are sent to a printer engine.
