Converting a 2.x Profile to the 1.0 Format

The ColorSync Manager provides the CMConvertProfile2to1 function to convert 2.x format profiles to the 1.0 profile format. Because 1.0 and 2.x scanner and monitor profiles generally carry the same required color information, no accuracy is lost in converting from one to the other. With printer profiles, however, some accuracy will be lost by conversion, leading to significantly different results. Because of the possible loss of accuracy in some cases, 2.x to 1.0 profile conversion is not encouraged.
