Hello,
I have a problem that I can't solve. I created a .ai file in CMYK color mode and I've also converted the photos in my file to CMYK.
In View > Proof Setup, I have the workspace set to CMYK. My printer tells me that the files I send are in RGB, I'm pulling my hair out, how is this possible?

It can happen at the moment of creating the PDF...

Are you saving, exporting, or printing to PDF??

But if that's the case, your PDF might be just fine and your provider could be mistaken....

Thank you for your reply,
I am saving as a PDF from Illustrator CC.

If you save as PDF, the color space is the one declared in the menu "file/color space of the document/CMYK (or RGB) colors".. I see no reason for it to change to RGB...

If you have Acrobat "pro", you can check your PDF with the "print/Output Preview" function.

I don't understand either and unfortunately, I don't have Acrobat "Pro" to check...
Thank you again for your help.

If you want, create a PDF file as you usually do and upload it for download at https://www.cjoint.com/ and I will pass it to the Pitstop inspector to see if it's okay or not...

So... your file is indeed in CMYK... that's for sure.

However:
Your background black is in four-color black, meaning it is separated into the 4 colors (75,67,68,90), which may be intentional, but for an offset printed document (which means color separation), using 4 colors poses a risk of registration issues in the text.

You should therefore create a 100% black with, if necessary, a support of cyan at 30%.

As for the reserved text, it is not 100% white... This may also be intentional, but honestly, I don’t really see the point...

Lastly, you created a solid black, but in relation to your cutting lines, there is a lack of bleed... remember to add some.
