It's my understanding that since CMYK is basically a device dependent
colour representation intended for optimising colour rendition on a
specific device, the actual transformation of RGB into CMYK must take
into account the device characteristics. This implies that any procedure
to perform such transformation must be parameterised with device
characteristics. Did I get something wrong, or was the posted code
fragment indeed tied to a particular device? I'd be interested in
hearing views on how parameterisation might be done, too.
