4.7 Review

Under this tab you will find some useful quality assurance and editing
tools.

4.7.1 Validation

This tool allows you to check the quality of any profile and calibration,
not only those created with SpectraView Profiler.
After measuring the validation patches you see the „Validation Results"
window. The measured values are compared with the reference values
calculated from the ICC profile. For each patch you will find a DeltaE
information along with Deltas for L, a and b separately.
display CIE LAB
This check box lets you switch between Lab and XYZ values, it is
checked by default.
Tolerancing model
With the radio buttons in the upper right corner of the window, you can
switch tolerancing models from DetaE 94 (de- fault) to DeltaE (Lab). The
latter is still the standard method for determining the distance between
2 colors, while the first is more accurately adapted to the human visual
system.
