Newest free PDF/X workflow specifications V4 released by the Ghent Workgroup

The world’s graphic arts experts have come together to release v4 of the Ghent Workgroup specifications (http://www.gwg.org/GWGversion4.phtml) for automated workflow efficiency in the range of application and output environment.

V4 of the specifications supports Adobe Acrobat 9 – which itself
includes Universal Proof of Preflight developed by the Ghent Workgroup.
Heading the list of additional enhancements to v4 is a check for
missing glyphs, one of the leading causes of preflight and page
production frustration.  

GWG’s specifications have become the international benchmark for PDF
quality assurance. The free specifications are utilised by designers,
prepress and printers all over the world.

"This is more than a minor update. It is a collection of feedback from
the industry and associations over the last 3 years that was
incorporated in the GWG v4 specs," says Peter Kleinheider,
Documentation Officer for the GWG and Print Publishing Technologies
Manager for callas Software. "The main interest was the reduction of
unnecessary restrictions like the use of double byte fonts or to ignore
elements completely outside the trimbox. On the other hand, the check
for image resolution or line-width was adopted to reflect today’s
printing capabilities."

Other highlights of the v4 specification, according to Kleinheider, include:
– A response to the growing amount of font problems in pdfs. Now all
font-related restrictions introduced by the PDF/A ISO Standard are
mandatory. 
– In response to the increasing use of standardized ICC Profiles, a set
of recommended ICC-Profiles to be used for the various printing
conditions of the market segments for which the GWG supplies
specifications (http://www.gwg.org/colormanagement.phtml).
