The calibration cap of your Colourpin II device must be treated with extra care. If the calibration cap gets dirty or compromised, it will affect the accuracy of the scan results.
Replacement calibration caps are available for the Colourpin II, to order please contact ncs@verivide.com
Colourpin Pro and Color Scan devices have a built in calibration tile, if these are damaged the device will need to be replaced.
