3. REsults and discussion
The results of the sequential execution of the algorithm for each
gradation surface (RGB) and two initial colorants (CMY) depicting the
projections of the ideal colorants on the corresponding surfaces are
shown in Fig. 3. At the first look, these projections should complement
each other in areas where the geodesic of one surface fits its boundary.
As follows from Fig. 3, it is not so. This can mean only one thing: the
ideal colorant does not lie on any of the surfaces of double overlays
but is inside the body of the color gamut of the printing system. In
other words, more than two initial colorants that are necessary for its
formation.
The projections of the ideal Magenta on the Blue and Red surfaces are of
particular interest. The broken character of the projections is related
to the fact that the localization area of the ideal Magenta is close to
the singularity points of the formula dE 2000. In
the case of electrophotography, it is obvious that modeling of the ideal
colorants is at the moment rather speculative. The real implementation
of toners with the ”ideal” colors for use in printing systems is
impossible for reasons that formed the basis of the Yule-Nielson model.
When hypothetically creating these ideal colorants, it will be necessary
to completely revise the model of subtractive color synthesis.
