ABSTRACT:
One aspect of the disclosure is directed to a calibration system. The calibration system includes an imaging device including a predetermined print engine capable of being calibrated and a calibration sheet. The calibration sheet includes at least one visible calibration reference region including a given mix of pre-selected reference colorants printed in the calibration reference region on the calibration sheet. The pre-selected reference colorants have been previously printed on the printable calibration sheet using a different imaging device that is different than the given imaging device and that has the same print engine as the given imaging device. The calibration sheet includes freshly printable target regions on the calibration sheet. The given imaging device is configured to enter into the calibration mode, wherein the given imaging device is configured to freshly print a mix of colorants corresponding to the pre-selected reference colorants onto at least one of the target regions.
