Round Trip Test

Gamutvision Round Trip Test offers an effective way to evaluate the implementation consistency of the generated icc profile.

Following computations will be performed when actual RT test is executed.

Step 1: Map a printer profile's gamut boundary to L*a*b* using AToBn and that
            forms the Reference Lab values.
Step 2: Map the Input Lab values back to printer RGB (or CMYK) using BToAn.
Step 3: Map the printer RGB (or CMYK) values to L*a*b*, again with the AToBn
            and that constitutes the Target values.
Step 4: Compare Reference and Target Lab values.
            If the profile is performing flawlessly the result should be reversible and
            there will be little difference between them.
