Opacity Issues with Placed Items

I have experience a potential bug where items that are placed with 100% opacity are appearing to have lowered opacity. After playing around a bit, I noticed that it happens when I change the display performance to high quality. 

 

Details:

This is a CMYK document intended for print. The blue and black swoop is an .ai file in CMYK, and the image underneath is a high resolution photograph. 

 

Why is this happening? Is it a bug, or is there a way to fix it? I like to work in high quality display so I can see what the finished product actually going to look like, but this is infuriating.

You  should also check that you don't have a blend mode like Multiply applied to the .ai file

You hit the nail on the head my friend. The black element was indeed set to the multiply blend mode. 

Thank you!!

Have you considered set the Edit > Transparency Blendspace > to RGB? Later, when you export the PDF, you can choose a CMYK destination.

This might be a black overprint issue. Check the Illustrator file and make sure that black shape is not set to overprint.

In Illustrator, Windows > Attribute > Overprint Fill
