When I save my RGB file in PDF it turns CMYK

I have a design which consists in a DIN A1, very colorful poster. When I save it from Photoshop in PDF keeping all the layers, and then open the PDF, it keeps all its original colors, but it takes a looot to load, so I tried to merge all the layers in Photoshop and save it in PDF again. When I open that PDF file, it looks normal, with RGB colors, but when I zoom out it suddenly turns CMYK, and even if I zoom in again it stays CMYK. I have 3 more posters with the same dimensions and it happens to all of them. Why does it happen? How can I solve that?

I wonder if the Print Presets have anything to do with it. When you go to Save as... and choose Photoshop PDF, you are given a choice of Print Presets:

Some will perform RGB to CMYK conversions, but if your printer does not mind RGB, try PDF/X-3 or X4

Press Quality converts RGB to CMYK  PDF 1x/a does the same

PDF/X-3:2002,  compatible with Acrobat 4 and that means that it flattens transparency, but it doesn't perform any color conversion.

PDF/X-4:2008 is compatible with Acrobat 7 and above. No color conversion. RGB stays RGB, CMYK stays CMYK, spot stays spot and this supports live, unflattened transparency.

I'm not a Press expert, I just recall this from an Adobe Acrobat course.

Nothing, it keeps doing the same

The thing is that it doesn't happen with smaller files, like DIN A4, it just happens with really large files

You'll have to explain this in a little more detail. A file doesn't "turn CMYK" by zooming, that's not possible. Exactly what is happening? Can you post screenshots? What makes you conclude it has been converted to CMYK?

It literally does that, I mean, the document doesn't turn CMYK per se, it's like it changes its display colors when you open the PDF and zoom out, it isn't a problem with my computer because I've tried opening it in other computers and it does the same, even in the copy shop's computer.

I know it's CMYK because when I was doing the design I was checking the CMYK colors constantly to know how it would look when I printed it. The thing is that I need it to look RGB on computer because the professor is going to look at the pdf files and I need him to see how it would look in RGB, which are its original colors.

Look (you can see it better on the green bugs):

The same EXACT thing is happening to my PDF coming out of Figma. It looks fine whenever I initially created however whenever I zoom in it will suddenly turn CMYK. I have gone into the settings to change it to Apple RGB viewing and then save it. However it reverts back to a CMYK.

Hi c.pfaffenbichler Figma appears to be an image app: https://docs.merkulov.design/upload-and-replacing-images-in-figma/

 

I hope this helps

Same thing here, exporting from Figma. Took me forever to get RGB back. Went to Tools, Print Production, Preflight. Then PDF fixups, convert all pages to RGB, and then went through the prompts under the standards, saving as a PDF/A.

 

This is definitely an Acrobat issue because the settings I used to export from Figma were set to RGB and the original pdf views as RGB in Preview. I've had this happen from files exported from Illustrator, too.

 

Adobe needs to fix this.

1) If this is an Acrobat issue, then this would be the wrong forum to note any possible issue/bugs

2) Without sample original/before files and files after the issue appears and clear steps it is hard for say what is going on

No, I wouldn't think so. The discussion was four years ago.

Myra, are you asking because you believe you have the same problem or similar to that described above? 

If so to help, we'll need a comprehensive step-by-step description along with application program version numbers and screenshots showing the process you use to save the PDF.

And then how do you open and analyse it to see that it's become CMYK? Screenshots please

 

insert any images into the text using the filmstrip icon above the mesasage box, do not attach, many helpers here are reluctant to open attached images due to virus issues. 

 

I hope this helps

Please be sure to explain what you mean by " I have gone into the settings to change it to Apple RGB viewing" as I can't think what you mean by this, there is no setting option I can think of for "RGB viewing".
