Color separation all wrong when exporting PDF-X3 or X4

[Gaunilo]

I tried to export a document into PDF-X3 or X4. When doing so…

…text in black got separated into CMYK

…text and elements on a background lost all trappings.

Only resolution was to export in PDF 1.7

Whatever adjustments are made in the pdf export menu get ignored/overwritten.

Quite annoying to be honest.

Hi @Gaunilo,

Have you got a sample document ?

 

[Gaunilo]

Can I send it to you personally… don't want to distribute it here on the forum.

 

[Gabe]

You can use this link to upload it : https://www.dropbox.com/request/hEXA21BrYUeiJPyWEr2i

[Gaunilo]

I've uploaded it. 
Sorry for the late reply… I forgot to set notification on replies. My bad.

I do hope you can tell me why I was unable to produce a k-only pdf.

Thank you very much!

Thanks. It does seem to be a problem with PDF/X formats. Issue logged. You could use PDF for export as a workaround?

[Gaunilo]

Sadly I couldn't even exporting as PDF 1.7 didn't lead to a correct result consistently.
In the end we fixed it in the RIP at the printers. Made me look like an incompetent fool.

As I want to use Publisher for many upcoming book projects it would be great if you could tell me how to fix it. 

Thanks a lot!

Did you have problems with the same afpub file? If I export it as PDF (for export) I get the correct result, with only one(Black) plate. 

[Gaunilo]

Yes, I did. 
I have no idea what goes wrong. 
Can you please send me a screenshot of the settings?

 

 

[Gabe]

Yeah sure:

and here is mine… 

[Gaunilo]

If you send me a new link, I'll upload the PDF created with it… if it helps.

I've reactivated the original link: https://www.dropbox.com/request/hEXA21BrYUeiJPyWEr2i

[Gaunilo]

Upload complete.

Thank you!

The pdf you've attached is greyscale. What do you this it's wrong with it?

[Gaunilo]

In that case everything is ok. 
My printing house said my PDFs are all in CMYK.
Either they made a mistake or I did.

Anyway – thanks a lot!
The PDF X4 is still unresolved but you said you already logged it.
So thanks for that as well.

 

Sorry for the bother.
