Just wondering if it's possible to try to tweak the CMS some to get it perfect. Out of the box my colors are close but need just a little tweaking (specifically Magenta and Yellow) to get them almost perfect. If I slowly adjust the CMS controls, what should I be looking for to see if they are causing unwanted negative impacts?
Hi, it need some practice and continuously verification of each correction step to see if the combination of controls you used don't introducing problems to your colors.
Each CMS control has it's own 'safe working range', and the combination of correcting values you use to one color may interact other colors also.
To be sure about your each step you have to verify each calibration step by looking some color saturation/luminance ramps patterns.
This is the reason I have added more than 150 Color Reproduction Patterns
to my calibration disk, to be able to identify problems that meters don't see ,when you will measure only a few color points for verification.
Sometimes extensive usage of the available internal calibration controls values (for the hunt of the lowest dE numbers); this can introduce problems to the display that it's difficult to measure, that's why you have to test this with color reproduction patterns.
Here is an example of a problem:
