PROBLEM TO BE SOLVED: To avoid drawing corruption due to an ROP process on a memory-saving rendering system by avoiding drawing corruption due to the generation of MSK during CMYK rendering, for an area where predetermined ROP is determined and DST remains. SOLUTION: A drawing system that performs rendering in CMYK using a raster operation determines the raster operation designated; converts the CMYK to CMY according to the result determined; determines if an output destination becomes translucent due to the data to be drawn and the raster operation; creates a mask pattern based on the result determined; and changes a rendering process according to the mask pattern created.
