Title: Re: Colorsync-users Digest, Vol 4, Issue 4
Hi Peter,
The G7 (Gracol) press calibration method is based on reading Lab values and translating the needed changes to match the target Lab values into adjustments in the TVI curves.
Obviously there is a bit more to it than that, but above is essentially what it is all about.
Best regards,
Dan Wilson
