I have an Illustrator document with placed 3 color images (CMY) that is showing black info when I view it using separations preview. The placed photoshop file is a CMYK file and does not have anything in the black channel. Im using Illustrator version 29.2.1.

Kinda making me crazy.

Your color settings with CMYK: preserve embedded profiles will convert the Gracol to the current Swop working space. Going from a 4 color space to 3 color Lab to another 4 color Swop, which will generate 4 colors including black.

The default settings: Preserve Numbers (Ignore Linked Profiles) makes sure that no conversion takes place and that black is not regenerated. It would not matter that much for images in general but it it not a good option for vector files and your example image when you want to keep the numbers.

So either use Preserve Numbers (Ignore Linked Profiles) or use Edit > Assign profile to make the profiles the same. the

Try to focus on your file's abolity to get "proofed". If the is nothing in the Black channel, then there is nothing in the Black channel. Simple. Do not over think it.

You say shows info in the Black channel. What exactly?

And can you show us your Color Settings. The default would be set to preserve numbers to avoid conversion.

.ai file had a swop profile

photoshop files had a gracol profile

When we changed Color Managment Policies to OFF and open the file in ai version 28.7.3 it works

The .ai file previewed the images correctly CMY

Doing the same thing in version 29.2.1. kept showing info in the black channel.

This is how I usually have my color settings
