What happens if a proof fails verification?
We throw it out, recalibrate our printer, and do it again. Believe it or not this does happen, despite our best efforts to maintain calibration. Changes in humidity, temperature, ink levels, etc, can all affect this process and printers often go out of calibration. This is another reason that having a verified proof is so important. We do not simply queue up a bunch of proofs up and “let ‘em rip”; each proof is proofed with care, and individually verified after proofing. Because we do have to throw out proofs from time to time, we are slightly more expensive than other proof providers out there.
