The effect of the overprint flag depends on the current color space
and the colorants available on the device. The graphic operation that
marks the raster memory is insignificant.

CMYK image can overprint non-primary separations.

An image in separation color space can overprint other separations
including primary separations.

DeviceN color space works as multiple separations.
