The first two plots depict the CMY gamuts measured measured on the
computer monitor before and after calling the function, 'Convert to RGB'
for both Engines along with the gamut of the printout. It is obvious
that the white point of our spectroradiometer has had an effect on our
measurements.
The third plot shows the slightly different effects each engine has
on the printout of this function.
The thin red line is our 'ideal gamut' associated with the full color
spectrum.
