I like this software more and more, I keep finding more uses and valuable feedback about profiles and the colors then define.
glad you like it. I’m also glad you are taking the time to explore color using it.
I’ve been selecting individual colors in a color list and doing so on my XP machine sometimes creates an infinite loop in the Plot Item palette, my attempts to recover from the loop crash Color Think. On the mac I can drag a color from the color list to the Plot list and that works fine.
are you trying this on the most recent beta? (b15). If so we’ll work at reproducing it here and killing it…
On another note, is it possible to take a CMYK image using a refrence profile like SWOPv2 into Lab and then back out to an inkjet profile and use Color Think to reveal what the CMYK build is?
ColorThink Pro will do a better (easier) job of this but it’s not shipping yet (soon, really, honestly…)
But, you can do it in the current version using color lists rather than images.
Follow these steps:
- open a CMYK data file (there are a couple in the “stunt files” folder)
- drop (or open) your SWOP profile onto the color list and CCT will generate Lab
- you might want to change the intent to rel col here…
- choose file:save as… and save the Lab data to disk
- open the Lab file into ColorThink again
- drop your inkjet profile onto the list and select your desired intent
- then you will see the CMYK inkjet build that results from the original SWOP CMYK.
A bit convoluted but it works.
The Lab file is a pretty good reference file for various tests as it is now a bunch of in-gamut SWOP colors.
You can also load the Lab color into the grapher and plot as vectors using the Inkjet profile as the destination. Then you will see the color shifts introduced into the SWOP color by the inkjet profile.
