Hello Wiki-Team,
I think I found something that would help future Users like me, and thus should be mentioned in the wiki:
(I'm a Beginner, first time Inkscape for an Uni-Project),
For a printing-service, I needed the CMYK-Colorformat. (In an PDF).
But the recommended Extension (http://wiki.inkscape.org/wiki/index.php/ExportPDFCMYK) didn't work for me.
(There was an Error during the Exporting).
However, following process worked for me:
1. Export to PDF via the normal Export-Function. (Result is a Cairo-PDF in RGB-Colors)
2. Use ghostscript to convert it to CMYK: (found at http://zeroset.mnim.org/2014/07/14/save-a-pdf-to-cmyk-with-inkscape/)
gs -dSAFER -dBATCH \
-dNOPAUSE -dNOCACHE -sDEVICE=pdfwrite \
-sColorConversionStrategy=CMYK \
-dProcessColorModel=/DeviceCMYK \
-sOutputFile=document_cmyk.pdf \
document_rgb.pdf
This process was much easier for me, as I only had to execute one Command Line, instead of installing two seperate Programs.
And it was the only one that worked, which was crucial, as I had deadlines to follow. And I didn't notice any changes in the Appearance of my file, so the colors were, to the eye, perfecly preserved, even on the eventually printed PVC-Plane.
Could you add this to the "ExportPDFCMYK" Wiki-Article, that this process existst?
I would be very thankful to that! And maybe future Users too witch the same struggles I had.
Best regards,
Niccolò Rigi-Luperti
