For one thing the inks were oil based. That's a primary feature of how lithography works.
A few years ago I tried to force an offset transfer (The more proper name for a wet sheet transfer) I took a worn common, soaked it and the paper, and clamped it between boards in a vise for a couple days.
No transfer of any ink, although it did pick up an impression of the woodgrain.

Steve,
On more than one occasion we've seen a group of cards listed individually by the same seller where most of them have transfers on the front
also some of them have paper stuck on the front and some have paper loss on the back. I remember on at least one occasion it was a
seller/dealer that sells a lot of T206's on ebay. My thought was that they had been stored in a box or something that had got wet at some
point and dried out over a period of time and that was how the transfers occurred.
If what you say is true the only explanation I can think of is that they
were soaked in a chemical to separate them.
