I must have downloaded that earlier. When I save the file I get a
warning message and the file contains zero bytes. Has anyone used this
extension successfully? It looks like I am missing a python file
somewhere.
Do you have UniConvertor 1.1.5 and a current version of ImageMagick
installed?
Attaching a google-translated version of the web page. Note the hints
about putting objects with transparencies (gradients, filters,...) on a
separate layer called 'Background'. Also, the extension apparently only
handles regular paths (don't know about text objects, possibly need to
be converted to paths as well?).

Extension to PDF export in CMYK
-------------------------------
Extension "Export to PDF CMYK" generates a vector file in PDF format using the
color system CMYK. The elements of the resulting PDF file to preserve the exact amounts
that were applied in the art in Inkscape, different export pattern made by Inkscape using
the Cairo and applies only values RGB to the elements. The extension uses the software
"UniConvertor" to generate the PDF file. The extension can still be improved,
but it gives some acceptable results.
Installation
------------
Before installing the extension, install LAST version of the software
"Uniconvertor" and "ImageMagick" on your system.
Unzip.
If you use Windows, wait a while longer. The extension still does not work in Windows.
If you use Linux:
Download the following files: pdf-export-cmyk.py export-pdf-cmyk.inx
Copy both files to the folder
/usr/share/inkscape/extensions
Use
---
Before generating a PDF file, you need to convert all the elements in the path (or curve).
A quick shortcut for this is Ctrl + A and Ctrl + Shift + C. Put all the elements that you
want to be in the PDF file within the page.
If you have objects with gradients, transparencies, filters and other special effects, you
have to define them in another layer to the extension generate a corresponding bitmap in
the PDF. Put all these elements in one layer. Change the ID of this layer to the
background.
After setting the layer with ID "background", click "File" -
"Save As ..." and select the file type "PDF CMYK (*.pdf) ". The
seguite window appears:
<

See details of the options:
- Rendering special effects
Defines whether you want to convert bitmap objects marked for conversion.
- Export only selected
This option causes the extension to generate a bitmap only the layer
"background" and only her. If this option is unchecked, the PDF will have all
the elements that appear on art created in the bitmap.
- Rendering resolution (dpi)
Is the value of IPRs in the bitmaps that you want the resulting PDF file. The more DPI,
higher quality and larger file size. For printing graphics, 300 DPI is recommended enough.
- Preserve Black
If this option is enabled, the CMY color bitmaps will disregard the existence of pure
black (100% K). Thus, the result is that the colors CMY pure black will not be
"leaked." Very useful option for graphic printing.
- ICC Profile
Applies the selected profile of Color Management in TIFF image in Inkscape.
FAQ
---
- This extension uses that color profile?
The profile defined in the "Color Management" in the configuration window
Inkscape.
- Why is it taking so long extension to generate the image?
It uses external processes to generate the files. Simply put, it opens another Inkscape,
export images in PNG format, use another program, ImageMagick to convert images to JPEG
and PNG UniConvertor to generate the PDF.
- Found a bug or error in the extension, what do I do?
