reading data again
ColorMaster itself stores all the data as spectral data. If you decide to change the method you should be able to use the stored data in ColorMaster to create a new sample/standard with a new colorimetric setting (D50/2 in this case) if you want to go down that road.

If the instrument is connected to the software, it acts as a sensor only, so that whatever you have the instrument set for will be overridden by what the software is set to. Also, like the instrument, the software does not save colorimetric data either, only spectral data. The spectral data is converted to colorimetric data based on what the instrument or software is set to display.
That said, if your pressmen have set ANYTHING to D50/10, just change the Ill/Ob to D50/2 and the readings will be displayed as that and be accurate for D50/2. You can even change it to any other Ill/Ob combination. We use the calculating power in the PC and instrument to do all the conversions.

The saved custom colors from our color library (we create custom colors when we can't hit the Pantone) are showing 50/10 under "Obtain Reflectance Date" (under edit/standards), and the "Standard Tolerance" tab is also showing 50/10. Won't we still have to edit any custom colors created outside of the Pantone 2005 library and edit the database to show 50/2?
Sorry if I seem thick on this...
