If the bottom is cut off in a 1-D code, you're in trouble, as it may
confuse the length algorithm. And you're better off saving whatever
redundancy exits to deal with the errors you report (smudging,
folding, etc.) rather than clipping. Better to leave plenty of
engineering tolerance, unless there is a reason not to do so.

Talking about smudging, one advantage laser has over inkjet is
reduced potential for smudging.

Best regards,
Arthur
