Store the calibration color card (color target) in a dark, cool and dry place; preferably 70°F (21°C) and not exceeding 50% RH. Handle the Target carefully to avoid kink marks, scratches and fingerprints.
Whenever damages and discolorations are observed/calculated by the Delvo®Scan software, the calibration will be rejected. In this case the color card should be rejected and replaced by a new one.
