This reminds me: the head of my lab here recently showed me some original
line art, now several years old, that was on some very plasticky sort of
paper which may very well be the same stuff Silvia refers to. All of the
drawings are full of very pronounced wavy ripples about half an inch wide,
like sand on a beach, and they are making proper reproduction impossible
given the stiffness of the paper. Since I don't really know what the
composition of the drawing surface is, and he doesn't know, I was hesitant
to make any recommendations as to how to remove the wrinkles without
damaging the inking (it doesn't look like any fixatives were applied).
Slight dampening and then either pressing (as in a plant press) or ironing?
Between sheets of what? Any other ideas?
