I have a text in my .cdr file. I use the CMYK color mode. The text I have is 0% Cyan, 0% Magenta, 0% Yellow and 100% Key.
I publish the .cdr file to pdf, with these color settings:
Then I open the .pdf file in Adobe Acrobat. I go to Tools->Output preview to see the color separation. I choose Eurostyle Coated v2 from the combobox. The I turn the checkbox with Yellow on, and the other checkboxes (for the other colors) off. The problem is, I can see the text, even though Corel Draw says it doesn't have yellow in it.
Why is this happening? How can I fix it?
Btw my file is for making an offset plate, I don't know if that's relevant to the question.

No, the 100%K color doesn't change when you publish as PDF.
The problem is about the color profile: according with your capture, you're using "US Web Coated (SWOP) v2.". First of all, you should activate "EMBED the color profile" Then, if you open the PDF with Acrobat you should use the same color profile. (US Web Coated (SWOP) v2). If you create a document with US Web Coated (SWOP) v2. and preview the color separations using Eurostile Coated v2 or other, the results will change. It's like to use a different language, it's something similar to send a message on english to France, if somebody read the message on french surely will believe that all the content is wrong. You should use in Acrobat the same color profile of the CorelDRAW and the PDF document.
The most important thing is to know what color profile is the best option for your job. This is relative to several factors, such as the world region you live (ie, Europe, USA, etc) , the kind of paper you will use for print (coated, uncoated, etc). My personal advice is to use PDF X/3 and choose "compatibility with Acrobat 8.0" or higher on the "General" tab.

I thought I fixed the problem. When I published to PDF, I checked the option 'Embed color profile: US web coated (SWOP) v2', and then when I open the pdf file with Adobe Acrobat and choose 'US web coated (SWOP) v2' from the combobox in Tools->Output Preview, the text is 100%K (so there's no yellow, cmyk and magenta, just as it should happen). And I was happy. And then a problem occured.
I sent the studio which makes the offset plates the same PDF file, and when they gave me the 4 offset plates, I saw that the text was again made from 4 colors. I assume that happened because they use another Color profile. Am I right?

Yes, of course.
For output plates, it's necessary to use the same color profile, or convert and embed the color profile if they want to change it.
Most likely the problem is that you embedded a profile at all. The issue with the first scenario was you proofed in a different color space causing a conversion. The problem with the second scenario is that you embedded a profile at all. Most pre-press shops in reality use postscript color management and just pass cmyk numbers along. In that workflow they in general strip embedded profiles, however, in this case they must have had their RIP set to use the profile which caused a conversion. Consult your output provider and request PDF creation instructions.
If you are going to embed a profile, you need to ask the printer what profile to use and use it. Acrobat will automatically know what that profile is and there is no need to choose it.
