They're interesting examples none the less. In my opinion, just because something's a scrap (aka reject) doesn't automatically mean it's worth extra.

Printers ink doesn't dissolve in water, so if it was a chemical think it would have to be some sort of solvent such as rubbing alcohol or paint thinner. I've seen chemical accident cards before, sometimes that made the the ink run like a tie-dye. When forensic examiners test ink for identification and dating purposes, they first dissolve it in alcohol.

One thing as far as identifying printers mistakes, if there's bad registration-- meaning really bad overlapping of colors, one color way off--, that wouldn't be made by alcohol or environmental accident. Those should be more obvious as scraps. Some of the really really bad registration mistakes are quite impressive looking too. But perfect registration is rare for T206s, so it would have to be really off for it to gather a premium in value.

I had some modern Fleer baseball cards with a football backs. Makes you wonder how errors that big can happen.
