Unfortunately it is not possible to print the ColorCard of ProScan yourself. It is produced by means of a special printing process and afterwards tested on a special device for colour fastness.
Only this way can we guarantee the high accuracy of measurements made with the ProScan test kits.
Which way round do I place the ProScan analysis strip onto the ColorCard?
On the ColorCard the "top" and "bottom" are indicated. When picking up the test strips you automatically hold the "bottom" side. It’s the side with no analysis fields on the strip. On the "top" side the analysis fields are printed right to the edge. An error message appearing in the app usually means the analysis strip has been positioned on the ColorCard the wrong way round. Just correct the position.
