PDF exports are turning images pink

[STEVEN28465331qzsj]

Hey everyone, I'm really struggling here. Working on a document in indesign, in which i've imported jpegs (created in photoshop). Everything was going well, then I modified and saved a new Jpeg. Updated the link in InDesign, and now the pdf exports are pink. (primarily in the white areas of the black and white images).

I know that this often has to do with color profiles, but I cant seem to find the problem. 

Using InDesign 2025

Photoshop file is in CMYK mode. 

InDesign document is in Print mode. 

Transparency Blend space set to CMYK (though also tried RGB)

I've tried exporting to pdf using all the preset options. 

I've tried modifying output settings to "no color conversion" as well as "convert to destination"

Any suggestions?

(PDF attached. The original images have a pure grayscale background, no warmth or pink)

Just installed Revu. It's a Revu issue. 

BTW, using a browser search of this thread, you only mentioned Revu about an hour ago. That would have helped a lot. It's what I call an "oh, by the way" bit of information.

I turned of the CMYK color calibration, restarted Revu, and the color was correct.

I tried to turn off CMYK collaboration. It gets rid of the pink. However, it also made all the other colors look very neon.

Time to switch to the Revu formums...

I appreciate the efforts!

I suspect Revu, because of its nature, works strictly in RGB. The CMYK is a simulation* but not very accurate one. Probably didn't put much effort into this view because of the nature of their usual files. 

Why not keep both on your computer since it's included in the CC subscription. Set Revu as your default; right-click to open a PDF in Acrobat if there is a problem. 

*I realize that everything is technically a simulation on RGB monitors; I'm referring to how the program handles the CMYK preview.

Now that we've firmly pointed the finger at Revu I think it would be instructive to make an RGB copy of your image (in Photoshop, save a copy and open it, then Edit > Convert to Profile... and choose sRGB) and place that in your file. See how that behaves in Revu.

That gives the desired results! No pink.

As I mentioned earlier, working in RGB is really considered the best practice today, exporting to PDF with color profiles embedded. The printer will use that information to convert to the correct CMYK colors for output.
