Digital BW, The Print

Hi Paul,

For fine art (cotton) paper, do you use either the Krylon Acrylic Varnish B72 or 
Grumbacher B77 recommended by Merrill.  It mentioned that the Grumbacher 
B77 will not saturate the surface (referring to pastels) the way the Krylon B72 
tends to do.  What does this mean and how does the difference affect the 
way the print looks?  Do prints sprayed with these products differ much in 
appearance or toughness from those treated with Premier Art Print Shield, 
which is virtually invisible on photographic prints made with pigment inks on 
fine art paper.  Thanks,
