Re: [Digital BW] Re:Glossy, MAtte and Dmax- Is it physics?

2005-05-26 by Steve Kale

How many threads are discussing the same topic here?

If anyone has an integrating sphere instrument I would be really interested
in some actual measurements of matte black on matte paper vs photo black on
photo paper.  In this case, surface texture is taken off the table and we
can see whether there is a true dMax lead held by the photo paper.  I
suspect this lead is still significant but only a set of measurements will
tell the truth.
