At any rate, if you want a really good calibration system, the best system in my opinion is to follow Michael Koch-Schulte's tutorials using his RNP arrays to determine the color and Chart Throb to determine the curves. I don't recommend doing it the way I did, spending months going over and over and over things and calibrating dozens of pigment colors at many different concentrations, until I understood all the ins and outs of what was going on, but that's just how I am; I have to understand things. You can actually get to a very quick and reliable result just by following the directions.


Sorry, looks like I grabbed the wrong page. Although the page linked above is very interesting, it's not the page I meant to point to, a quick and basic tutorial:
