Just got back from a trip this afternoon, and then cut open the box with my new colormunki.
Read the quickstart guide, installed the software and feared the worst. My old spyder2express was just not able to calibrate the monitor to any degree of accuracy anymore, and when trying to print canvas on my R3000, i was having to make a lot of test prints to assure anything close to what my monitor looked like - very frustrating.
So munki arrives, i start in on the monitor, clicked bravely on the advanced process, and got a monitor which was drastically better than what the old spyder2 did for me. Having some momentum now, i decided to bravely click on the printer calibration and build a printer profile - not having too much idea of what that really was. (I wasn't brave enough to risk any of my expensive canvas for this stuff, so used glossy photo paper instead) But just followed software directions and printed the first sheet of color swatches when prompted. Then printed the second sheet of color swatches and then closed out the program. Seemed way to easy to even have a chance of working.
Then decided to reprint a photo i had done on canvas, and see how the paper print came out relative to my newly calibrated monitor. (i should mention in all honesty that my monitor is nothing special - just the lcd on my older Toshiba laptop) The printed copy of the photo - looked exactly like what my monitor looked like, even the toning. (my printing hell is suddenly appearing like its done a major turnaround)
Thanks to all that recommended the colormunki - expensive bit of kit but its sure going to save me time on test prints and other nonsense.
