That's interesting.

Here's the patent, which was assigned to ALC.

The "fabric" mentioned in the patent is not the Blanket, which was the covering on one of the main press rollers or anything wedged in between, but that does refer to the web itself.

Even if there was some sort of creasing damage to the blanket, that wouldn't produce solid lines of color. In fact it would generally produce the exact opposite, white unprinted lines. (Generally, as there's a possibility of some marks I've seen coming from a wrinkle but I can't say for sure that's what caused them. )
A sideways slip of the web would only produce wrinkles in one direction, along the web, and these scratches do exist in both directions, with a few cards showing an intersection.

There is some solid evidence that Some T206s were printed using a flatbed lithography press that printed from stones.
Have you found anything solid that indicates a multi color web press? It's possible, and I've seen a few things that make me think that a two color press may have been used for some of the production, but not much indication that it would have been a web press.

I can elaborate, but I'll probably have to draw some sketches, and it might be more appropriate in it's own thread.

What do you think Guys? Get into it here or in it's own thread?
