Can you check if Overprint is used?

Can you uncheck it? Does Overprint Preview show the logo?

[MFNF0101]

There are no changes. When i'll back on this window, overprint is check again 

[Ton Frederiks]

It looks like at least parts of your selection is using overprint. Try to select all, and check/uncheck until it is unchecked.

Hi @MFNF0101,

Sorry to hear about the trouble. I would like to know if you have tried opening the PDF in Acrobat? Does it look the same there?

Also, for testing's sake, would you mind flattening the objects or outlining the text to check if it appears in the preview app after saving it as PDF?

Moreover, I would recommend you update the Illustrator to v25.4.6 or v26.3.1 to see if that helps or not.

If it doesn't, please share the file, including link files, if any, and we will take a look at it.

Looking forward to your response.

Thanks & Regards,
