Conversely, since lithography requires the rejection of oil based inks by a damp stone or plate, water alone shouldn't cause a transfer. I tried with a T206 a few years ago, and at normal temperatures I couldn't force a transfer using just water. Embossing wood grain onto the card yes, any sort of transfer no.
Heat and or some chemical involvement would be required, eventually I suppose I could duplicate what would cause it, but haven't the time, budget or inclination. (It would also vary depending on the exact ink, and there may be different carriers for the colorant... )

Hi Steve

I appreciate what you are saying here. You speak from a Printer's experience. I, too, have had some Printing experience in a small Print Shop back in my High School years.

I singled out your last paragraph, because I, too, have for years tried to simulate "post-production" printing ink transfers with T206 cards. By simulating heat, humidity, and
with various solutions. I have NOT been able to get the ink to transfer from one card to another (even after lengthy periods of time). And especially regarding the ink on the
backs of these cards.....absolutely no transfers.

Apparently, American Lithographic used some very high quality (no-run) ink to print these cards. What is your thinking regarding this ?
