Improved handling of overprinting effects for PDF processing without flattening
Processing PDF data containing transparency or overprinting effects can sometimes lead to unwanted visual results if flattening is disabled.With the new functionality, GMG ColorServer ensures that color management preserves the visual appearance of overprinting areas as good as possible, even if the Flattening option is switched off.

Note: Please note that, however, color accuracy in areas with overprints and transparencies can be achieved only with flattening.
