Digital BW, The Print

USI 1.3 mil glossy laminate, the thinnest available. According to Dr. Work, 
the best method of protecting pigment inkjet prints (if you don't mind the look 
of it) is to laminate. Total encapsulation from moisture, pollution, UV 
filtration, etc. Kinda defeats the feel of Rag paper, but you could display it 
without glass this way. It does show the underlying texture of all rag papers 
(none are really that smooth) and increases Dmax to different degrees, especially 
on Epson Smooth Fine Art. Here's the data in order or apprearance:

Dmax

All except the Semi Gloss are MIS Ebony/UT inkset in 7500, Roark N-1 curves.
