Re: [BKARTS] removing label from vellum & terminology



Before you introduce heat or moisture on the vellum you could reduce the thickness of the label mechanically, like with an etching knife and a sensitive hand. You can start by scraping the material a small layer at a time.  Stop before exposing the bottom or adhesive layer and be careful not to etch the vellum.  Once you're down to the last layers you can test solvents with a q-tip to see if they soften the material.  Depending on the results, you might be able to swab the residue away or etch further to remove the adhesive.  Be careful with the angle of the blade- or find someone who has experience with these techniques, like a paper conservator.

My feelings on the "shadowing", from past experience, leads me to believe that some inks had to high a concentration of the "vehicle" that carries and binds the pigments.  It's almost like there was too much oil in the ink, and it spread to produce the shadows.  Sometimes it even eats through the paper.  I bet Jack Thompson can give you the info you need..
