[279] Side-by-side and Media relative evaluation methods
The traditional
side-by-side
evaluation method checks if printed colours exactly match the colours
of the reference printing condition. The
media relative
evaluation takes into account that the
paper white values of the printed media and the reference media can be different. Therefore, the
media relative method uses a non-linear algorithm to compensate for the different white points.
The
SCCA
(Substrate-Corrected Colorimetric Aims) evaluation method, used by IDEAlliance tests,
is also based on the media relative evaluation.
Target charts
The colour validation test prints target charts on the selected media, that you measure when they
are dry. The type of target chart belongs to the definition of the colour validation test or the
profile accuracy test. The charts must be printed on the media that you are evaluating.
For custom colour validation tests you can select one of the following charts.
