 <warning>Support for PDF/X is available beginning with version 0.93. This feature is
new and may not be 100% complete, yet. Feedback is welcome.</warning>
 
-PDF/X is a standard which faciliates prepress digital data exchange using PDF. Currently,
only PDF/X-3:2003 is implemented out of the many different flavours of PDF/X profiles. PDF/X-3:2003
is documented in [ISO 15930-6:2003(E)](http://www.iso.org/iso/en/CatalogueDetailPage.CatalogueDetail?CSNUMBER=39940&ICS1=37&ICS2=100&ICS3=99).

 ## Implementation Status { #status}
 
- **PDF/X-3:2003** is implemented to the degree that FOP supports the creation of the elements
described in ISO 15930-6.

 An important restriction of the current implementation is that all normal RGB colors specified
in XSL-FO and SVG are left unchanged in the sRGB color space (XSL-FO and SVG both use sRGB
as their default color space). There's no conversion to a CMYK color space. Although sRGB
is a calibrated color space, its color space has a different size than a CMYK color space
which makes the conversion a lossy conversion and can lead to unwanted results. Although the
use of the calibrated sRGB has been promoted for years, print shops usually prefer to convert
an sRGB PDF to CMYK prior to production. Until there's full CMYK support in FOP you will have
to work closely with your print service provider to make sure you get the intended result.
