Abstract
A method includes generating a machine readable code using each ink color implemented at a printer, printing the machine readable code on a first side of the medium, analyzing the machine readable code printed on the first side of the medium at a verification unit and detecting a side mismatch if the verification unit does not verify the machine readable code printed on the first side of the medium.
