Print to PDF on Mac resulting in black and white PDFs on Adobe Acrobat for Windows

Hi. My question requires someone with knowledge of both Windows and macOS.

 

I'm a Mac user and, for my job, I've had to save some documents as PDFs on my Mac to send to someone at work who uses a PC running Windows 10. I also have a work Windows PC that I use for testing the PDFs.

 

On my Mac, from various applications, I've been choosing Print and then Save as PDF. The resulting PDFs are in color when I view them on my Mac in the Preview app. On a PC, they are also in color when I open them in the Edge browser. But when I open the PDFs in Adobe Acrobat Reader on the PC--which is how my colleague is viewing the files--the documents are in black and white.

 

I do have a physical black and white printer (made by Brother). I wonder if somehow the printer's driver is causing the PDF to be in black and white when I'm printing to PDF. I wonder if I had a driver for a color printer whether printing to PDF would result in a color document, but it's just a guess.

 

If anyone has an explanation of what's happening and has a solution, I'd be very grateful.

 

Thanks!

    Correct answer Mirskyman

    The Save as Adobe PDF is available with Acrobat Pro DC and not with the Adobe Acrobat Reader.

     

    No, it makes no sense at all. The Reader should have zero effect on applications saving PDF. But then again, the whole print and rendering subsystem of MacOS is somewhat of a mystery. 😞

     


    Yeah, it's very weird. At least now I'm able to save PDFs that appear in color in all applications without having to re-export. Thanks a lot for your help and your suggestion of installing Acrobat Reader.

     

    I'll definitely keep Acrobat Reader DC on my Mac. I think its interface is pretty clunky, which probably was one reason I removed it a few years ago. But you, and my tests tonight, have convinced me that Acrobat is better at handling PDFs than Preview.

    We have no idea what's going on with the information you provided.

     

    There is absolutely no interaction between whatever printer drivers you have installed on your system and how Acrobat or Reader display the PDF file. And this is the first time I've ever heard of a symptom like this!

     

    The only possibility that I can think of is that is that somehow the Accessibility preferences (CTRL-k) on your system have been accidently enabled causing colors to be modified or even possibly mapped to black.

     

    If you could post a PDF file that exhibits this problem on your Windows system, we can try to duplicate your symptoms and if they are repeatable, try to find a solution for you.

    Dov, thanks for replying so soon after my post. Also, I'm honored to have a principal scientist helping me with my issue. I'm happy to provide a file for you to analyze. I created a sample PDF from Excel on my Mac and then I opened it on my Windows PC in Adobe Acrobat Reader and it's definitely in black and white in Acrobat. I also took some screenshots to show you what's happening on the PC.

     

    I didn't see a way to post the PDF directly to this reply, so I created an external link. Let me know if you have issues with it: This is the link to the sample PDF document.

     

    I have attached the screenshots below:

    Okay! Thanks for providing the file. Mystery resolved.

     

    The PDF file was improperly generated. It has what is known as an Output Intent specified within the PDF file. In this case, the Output Intent is for Generic Gray Gamma 2.2. Actually, any PDF viewer that displays this in color is in fact wrong. For the record, neither the Preview application under MacOS nor the Edge browser under Windows are anything near compliant with the PDF specification!

     

     

     

    The underlying PDF file does indeed have RGB colors. It is that Output Intent profile for grayscale that causes the PDF file to be displayed as it is. And that Output Intent profile isn't being added on the Windows end or by Acrobat.

     

    Quite frankly, I don't know what PDF creation settings you had in effect in the print dialog when you selected the option to save as a PDF file. On my MacOS 10.15.x system, I cannot duplicate your results in terms of creating a PDF file with an Output Intent profile, but the PDF creation on your Mac is definitely the issue. Is your default printer on MacOS a monochrome only printer?

     

    Perhaps if you can give a step-by-step with all settings description and screen shots of how you actually create the PDF on the Mac, we can help further.
