Re: QuadToneRIP new features

2003-08-02 by kiwikale

Many thanks to Roy for making all this hard work available and to Carl also for doing 
the 2200 profiles.  I have just one question for Carl.  Which of the three sets of paper 
profiles would you recommend for use with Somerset Enhanced Velvet from St 
Cuthberts Mill?  

Cheers

Steve

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
