Device + media is the useful unit
A device can behave differently across media, ink, profile and process conditions. Record the combination that the evidence actually supports instead of one universal green badge for the machine.
CALIBRATION / CONDITION REGISTRY
Keep process evidence
tied to the real combination.
Record which device, media and profile or process condition was verified, when it should be reviewed and where the underlying evidence lives. Overdue or review-marked records surface as an operations signal.

The registry records evidence; it does not perform calibration.
Due dates expose staleness
An overdue record becomes a review signal. The tool does not invent a calibration interval; enter the interval appropriate to your process, contract or internal quality plan.
Evidence reference matters
Use the note to point to the measurement report, proof, maintenance record or procedure kept outside this browser. Local text alone is not certification.
