Seaver/Clemens is more like the 90 Thomas. Probably not as severe, If I remember that thread right there's something like 15 cards affected by the same object that caused the Thomas.

I have some 77 Topps cloth checklists that have the same problem as the Flanagan/Wiggins.

It's possible that it recurred over a few sheets, but no more than a few.

When the operator adds water sometimes it drips onto either the plate or the offset blanket. If it drips on the plate it would probably only be on one sheet since the plate is wet and inked each rotation, and the pressure should squeeze out enough water to keep it to one sheet. I can see water getting on the rubber blanket maybe lasting a couple rotations under the right conditions.

If it was solvent, which is used occasionally to remove ink buildup on the rollers, then it might last a bit longer on the blanket. But again probably only one or two turns on the plate since the water would float it off and the pressure would push it out.

I do have one card showing where the ink floated on a very overwatered plate. Pretty odd effect.
