5.1 Parameters settings
"Parameter Setting" can set the color format, ΔE formula, QC mode and matching color chart.
Color format
The color format corresponding to the color space includes: Lab, Luv, LCh, Yxy, CMYK, RGB and Hex.
Users can select different format to tick according to their needs. Up to 3 items can be selected. Lab is
ticked by default. Options cannot be changed, so you can choose up to 2 items.
After this option is changed, the color format in the “Color Scan” interface will change accordingly. The
color parameters in "My Color" will also change.
ΔE formula
The ΔE formula corresponding to the type of color difference formula includes ΔE*ab, ΔE*uv, ΔE*94,
ΔE*cmc(2:1), ΔE*cmc(1:1), ΔE*00, a total of 6 color difference formulas. Users can choose one of them
as the color difference calculation standard according to their needs.
After this option is changed, the ΔE calculation of the "Color Compare" interface will be changed
accordingly. The results displayed in the "Compare History" should be recalculated and determined
according to the selected formula (if QC testing is selected, QC judgment must be recalculated based on
the calculated ΔE).
