I've become extremely leery of transfers, especially any involving black ink. I recently bought a couple items- Card proofs of stamps from the 1880's- neither of them had any transfers. When they arrived from the UK having been shipped together in the same inner envelope the black one had left a very solid transfer on the other one. So the ink hadn't actually dried in roughly 130 years!
The printing process was different, but the ink used was also oil based. Lithography uses less ink than engraving, but all that will likely be needed to produce a transfer of a black back is pressure and a bit of time. And since the base of the inks is probably the same, it should work for other colors as well.

Thanks Steve, I know you know your printing and appreciate your input on this. I also remember when you posted about the stamp situation.
I have a question- if a card came into contact with an oil based solvent, wouldn't there be some type of obvious staining on the card (from the solvent)? Also, wouldn't it do some type of damage or smearing to the front of the card that the transfer is on?
I'm just wondering if I took a T206 and placed it on top of a white sheet of paper with a little weight on it, say for a week or two, do you think I'd have a light print from the back on the white sheet of paper?
Sorry for all the questions- I appreciate the help.
Sincerely, Clayton
