I'm a beginner in Scribus and this is my first post on this forum.
Saving my Scribus file (1.4.2.) to PDF / X-3 only works with printer marks. Now my printer does not want any printing marks. If I do not choose one when exporting, the colorspace of my pdf becomes RGB. At least that's what the ImageMagick software tells me.
I specify that all included images are CMYK and that there is no other out of Gamut color in the file.
For now I have two alternatives:
1. I save my document in PDF 1.5 instead of PDF/X-3. ImageMagick validates the PDF, even without printer marks, as CMYK.
2. I give my printer a JPEG CMJN instead of the PDF/X-3, but you lose all the advantages of the vector objects, and this will not be possible with a document of several pages.
I find it amazing that ImageMagick does not validate my PDF/X-3 as CMYK only because there are no printer marks.
Maybe my PDF/X-3 recording settings are not good ? Have you ever managed to export to PDF/X-3 CMYK without print marks ?
Are ImageMagick pdf colorspace informations reliable ? Is there another software under Ubuntu 14.04 allowing me to analyze the colorspace of a pdf ?
Here are my export settings in PDF/X-3:
- Menu : File > Export > Save as PDF... :
- in the "General" tab :
- "File options", "Compatibility" section : PDF/X-3 in the drop-down list
- "File options" section : "Resolution for EPS graphics" : 300dpi
- "Compress text and vector graphics" checked
- section : "Compression method" : "Lossless - Zip"
- in the "Color" tab, "General" section : "Convert spot colors to process colors" checked
- in the "Pre-press" tab :
- "Printer marks" section : nothing checked
- "PDF/X-3 Output Intent" section :
- "Output Profile" : "Coated FOGRA39 (ISO 12647-2: 2004)" in the drop-down list
Thank you for your answer !
PS: setup : Scribus 1.4.2. in Ubuntu 14.04
