That sort of mark does happen, but it's less common. Those are also usually inconsistent. They may be in the same general area, but hardly ever the same. I have some on modern cards, but not on older ones.
The stone would be dampened, inked, then it prints to a rubber roller that is what actually touches the sheet. Lots of stuff can happen there too. Like cracks in the rubber if it isn't changed when it needs to be. But those show as white lines. (It's also very uncommon. )
