Probleme avec l'outil pipette

If the CMYK Illustrator .AI file was placed into InDesign, and the Illustrator CMYK .AI file already had swatches saved within it, then you would already have the Illustrator CMYK swatch in your InDesign swatch panel. Then you wouldn’t need the eyedropper.

Hi @Elsa Bordes,

Thanks for reaching out, and I'm sorry you're experiencing this issue.

Could you please confirm whether this behavior is new after the recent update(if possible, please check in Older version of InDesign as well)? InDesign has historically sampled the RGB preview when using the Eyedropper Tool on placed Illustrator (.ai) or PDF files, even if the source artwork is CMYK.

Also, does this happen only with .ai files, or do you see the same behavior with PSD, TIFF, or other formats as well?

If possible, please share a small sample .ai file and a short screen recording showing the issue. If the files are confidential, you can send them via Direct Message using Google Drive, Dropbox, or a similar cloud-sharing service.

This will help us determine whether this is expected behavior or a regression introduced in the latest update.
