Digital BW, The Print

Clayton...some time ago you commented favorably on your experience
with alpha cellulose-type paper (source? name?). 

I've recently used a lot of Illuminata Alpha (www.inkjetart.com), a
very cheap alpha cellulose paper...closely matches Illuminata
Ultrasmooth (100% cotton, no whiteners, slightly-cream) at half the
price (and it's two sided). 

Anyhow, this stuff is beautiful with portraits, would be deliverable
except that solid black areas have an odd glistening/textured effect
when views from an angle...unlike Ultrasmooth (or EEM) the surface
texture evidently isn't 100% matte.  

Clayton, have you continued to use alpha-cellulose? With your brand,
have you observed the black phenom I mentioned above? What's your
thinking about its longevity?
