As promised, I've got an update about the Color Error Threshold Calculator. The utility is now in good enough shape to be posted along with the article about it that I recently finished for our TAGA chapter at Clemson.

For those that have no earthly idea what this is about, the calculator helps educators and industry members determine how much color variance is acceptable for a given color. When trying to reproduce a color over hundreds (or thousands) of impressions on a press, there will be some periodic change. The calculator tries to estimate a Delta E value that is acceptable.

See the Color Error Threshold Calculator and read the article.
