That's really interesting.

I agree that it's not low ink. I believe they ran through top or bottom first, so running out of ink should be either the whole sheet, or a more gradual transition, or down the side. Down the side would be an adjustment the press operator can make. The inking levels can sort of be controlled to be heavier or lighter on different parts of the sheet.

I'm not thinking of too many things that could happen that would give that sort of transition and also the partial inking.

My current thought is that a piece of sheet was stuck to the blanket, so it got inked, but not well. But having just maybe a half inch or less peel off one end of a sheet would be strange, stranger that it happened multiple times.
