requires more memory, more time for creating pro
les, and, hence, may not be
suitable for general use.
It is also critical to note that the CMYK response of out-of-gamut colors to
the line stimuli should also be smooth. If discontinuities occur for the out-of-gamut
colors, then different mapping strategies may have to be used to preserve the
