Flatten transparency
Flatten transparency not working because its saying i have too many spot colours but i have no spot colours in my art
If I have more than 27 spot colours in my Swatches panel, I get that message, even if I use only 2 process colours.
When you use the Separations Preview, they all get loaded even if you have “Show Used Spot Colors Only” checked.
You can avoid it by using Select All Unused in the Swatches panel and delete the swatches.
