Re: transmissive densities - Glossy vs. Premium Semigloss

Hi Loris,

Thanks very much for the feedback and confirmation. I didn't lock, and
took my readings from two different prescans. I will re-do.

There are no negatives in my life, only positives (I work with polymer
plates). :-)

As far as methods, the procedure I've been developing is posted here:
