Hi Peter! Haven’t overlooked varnish, but I don’t see any evidence of it. I’ll take another look.Wade

Interesting question. My first thought is one you seem to have discounted already - a press run of varnish over those areas.Peter Spooner

Hello all,We have a number of related posters in our collection that are raising a question about ink colors and print process. They are printed by offset lithography on uncoated paper. Examination suggests the posters were printed in red, yellow, light yellow, green, and blue, with white areas of the posters receiving no ink (paper white). One portion of the posters have the red overprinting the yellow to produce orange. There is no evidence of halftone/ben day dots; the colors are printed as solids.
This is where it gets puzzling. The margins of the posters are yellowing significantly, and the reverse of the posters are yellowing uniformly edge to edge. The white areas of the image, however, are pristine, bright white.
Could the posters have been given an under print of white ink? Could the white areas have been matte varnished? There is no evidence of either that we can detect. The theory of a white base coat may suggest that the base coat was necessary for the transparent red (remember, the red was overprinting the yellow to produce orange, suggesting a transparent red) to be bright and saturated on the overall background of the poster.
You may have already guessed from the color scheme that the posters are original Woodstock posters, printed by Sidney Rapoport in NYC in the summer of 1969. How does one explain the bright white dove and lettering on these posters when the paper it was printed on is yellowing?
Any suggestions would be appreciated.Wade
