So, Can I use the colorimeter to spaot measure and edit in this way?
If yes, how should I convert the Colorimeter Lab output to RGB so I
can decide how to adjust the sliders?
Learn to speak Lab. It makes clear statements about neutrality without an RGB conversion: zero values in a* and b* means neutral; positive a is red, and so on around the color wheel.
Should I just try for a neutral
gray and assume that the colors will be ok?
When you are adjusting it is for the neutrals and near neutrals where such tiny variations are visible. So yes, just work on the neutrals. But the spectro and software have already tried to produce neutral for you already. If you have a printer with at least two gray inks, then printing neutral images will be much more precise than it will with printers that mix their grays from color inks.
One other question. Is there any way to go directly to the profile
editor after launching Spyder3 without rebuilding the profile?
Spyder3Print does not edit profiles, so there is no way to "go directly there". What it does is adjust build parameters from measurement sets, so it requires the measurement set(s) to do this.
