Question regarding the Spectro - When using it in measurement mode
do the reported values reflect calibration or is it reporting
uncalibreted Spectro data?
Measure mode reports spectro data, nothing to do with printer profiles, so in your meaning "uncalibrated" but the spectro itself is certainly calibrated...
For instance, if I perform the white
calibration using the tile on the Spectro holder I would expect the
measurement to report back zero for a and b values using the very same
tile. Is there a tolerance on this?
Why would you expect the spectro to report zero for a and b values? It should report a and b values representing the color of the calibration tile, which is what it does. The tile is measured by a reference device, and then by the spectro, and these values are stored in the device, for calibration by the user, to account for factors such as thermal variations.
