True, but if you're doing art repro work, colour accuracy is a MUST. I have some clients who look at a proof and go, "That colour isn't right!" I say, "Sure it is!" Then I read the original with a spectro, compare to actual, and say, "Oh, you're right - they area bit different." And when I saw a bit, I mean a bit!!! Some clients have an incredible eye for colour, but if you spent months slaving over a piece of art, you'd know the colours quite well too! :)


Small patch sets -eg the standard 343 Xrite target- yield very smooth
profiles with decent shadow detail.

I tried the 343 target with basICColor's Catch and CMYKick with fantastic results in a quick test. More testing needed.


Anyway, reading a few thousand patches with the iSis XT is much easier
now thanks to its huge maw and bar coded targets.

Here's a question - why doesn't GMG / X-Rite build in an error detection aspect to PMP? For example, you print the target, then scan in the ~4,600 colour patches using the iO. Inevitably, you are going to read a few patches incorrectly, even if you're using patch mode. I have scanned targets twice, then fed the results to Measure to see where there are differences, and it can pick them out. However, re- scanning individuals patches and editing the measurement file can be tedious. Would be nice if GMB "warned" you of suspicious reads, and re-read them for you. They / you could set a threshold between what should be read and what is read, and if the threshold is exceeded, it re-scans the patch.


Just an idea.

Derek
