Digital BW, The Print

Mike,

I have to go with Wilhelm for the accelerated aging tests.  I don't do those
(at least yet).  So, Premium Semimatte seems to be OK for long term use.

I'm not sure about short term stability.  It, like perhaps all glossy
papers, has a larger 1-day curing shift than matte papers.  The dmax can be
rather variable.  I've seen older test strips slip to 1.7, whereas others
stay over 2.0.  The ones that slip appear to have a matte, dull look
relative to the higher, glossier ones.  A glossy paper with a dmax below 2.0
is not good. 

On all glossy papers the MIS PK (can't speak for UC PK) tends to lose gloss
and dmax over the first few days.  I'm not sure PSM is any different than
other glossy papers in this respect.  A spray stops this.  I suspect the
acrylic coating on UC PK helps that PK keep the gloss without a spray.
Which PK does better is a complex function of printer and paper -- hard to
generalize, but the smaller the dot, the more likely UC PK (and MK) wins.

I appreciate the low bronzing and reasonable price of PSM rolls.  It would
be nice if it were available in sheets, but maybe they found a problem.  Cut
sheets have had minor feed problems in my experience, but not enough to
outweigh the advantages.  

My next experiment with PSM is going to be tape-hanging a large piece behind
glass like I would a matte paper.  If it looks good (and most glossy papers
don't due to not being totally flat) PSM might even replace the matte papers
I've traditionally used for the "fine art" displays.  Dmax matters.

Paul,

A while back you were very complimentary about Epson Semi Matte. You 
mentioned that it had a Wilhelm rating of 200 yrs. I checked it out on the
B&H 
sight and found that it was referred to as a proofing medium for its color
fidelity 
(positive if your doing color) but what made me nervous was that it also 
claimed excellent short term stability. 

Can I rely on this paper to be archival. To hold contrast and tone over
time, or 
even - for the infrequent occasion, color?

What is your experience/recommendation? 

Mike Kitei
