Are you sure it was a quirk in Illustrator?
I’d be more suspecting it was an issue with a downloaded updated pantone library in the new version with colors not used in the old Illustrator that was the more likely culprit?
That’s just a guess. For that, I’d blame Pantone.
(Unless it was a REALLY old version of Illustrator that used the old CVC libraries. Then that’s on whoever opened it with something that old.)
What smokes me sometimes is Indesign refusing to add Colors Used in .ai links to the swatch palette. It’ll put the used Pantones in there, but not the used CMYK colors. Annoying.
Huh? Never saw that before.
It will only bring in Pantone swatches.
The CMYK colours are then used in the CMYK swatches from InDesign.
If you want CMYK swatches - then make those Spot in Illustrator.
They input as Spot in InDesign.
Then in the Ink Manager in inDesign conver these to cmyk.
The only way I can think of to get those in there.
Another way - obv is to export your Swatches pallete to a ASE and load that in InDesign.
But it’s a good point - I never considered that before?
A quick way - blank page - copy your illustrator (select all - copy) paste it into the blank page in InDesign.
Delete the page and all the contents of pasted illustrator crap (don’t undo).
That’s a weird one Smurf! And yeah, when I really need the swatches, I just copy paste into an empty layer, add em and delete the layer. Sometimes I have to coordinate colors a little more than I should have to.
My project this weekend, if I can’t avoid it, is painting the bathroom. And the ceiling in the den. I almost hope it snows so I can pretend to go out and shovel instead!
