not sure you should...
you should calibrate each to a set standard rather than chase your tail in circles.
I started using monitor calibration a long time ago. Used spyder 2 pro and the several labs I use gimme what I give them, color wise.
I got an xrite thing and calibrated by 5d2's in LR for the most common lighting situations here at the studio. I don't bother for weddings as the lighting can be anything.
When I got my canon 6100 I got a color munki to calibrate as non-canon papers were inconsistent in what I'd get. Now it's no longer an issue. Made a BIG difference.
For whatever reason my 6100 is always printing denser (darker) than what I see on screen. I need to pull the blacks up by 15 points on color images and 30 to 35 on B&W ones. My one lab prints a tad dark (or should I say the blacks block up) on some B&W prints. I've not had this problem using simply canvas.
Before everything else, getting ready is the secret of success. -Henry Ford
