Digital BW, The Print

When I first asked about the permanence of InkJet VS Photogravure I 
mentioned a show I had seen at the Minneapolis Institute of Art. The 
pamphlet accompanying the show has a bit on Paul Strand and the 
Photogravure editions of The Mexico Portfolio. One was done in 1940 
and the other in 1967.


    " A heavy varnish, which has since darkened, was applied to the 
Photogravures in the first edition. By contrast, prints from the 
second edition appear much lighter in both tone and feeling"

	Just some food for thought
