Thanks Rick for the reply.
The ambient light is quite stable even though it’s not the best.
If I understand you correctly, doing a calibration, say each day, you would see a difference?
I did recommend to the photographer to calibrate monthly and to use the Advanced mode.
This question came up because they did one calibration using the Easy mode and one using the advanced and saw a difference. They then went and did another of each and each one was different. I thought that doing this may cause issues though but didn’t know why.
I have gone back to them and again suggest they use the Advanced mode with the ambient light check and only do monthly.
Using softproof, we get a very close match between monitor and print after doing this. Proving it is working.
Thanks again for you reply.
