Newest, Free PDF/X Workflow Specifications v4 released by the Ghent Workgroup
Acrobat 9, including New Universal Preflight, is Supported
GWG's specifications have become the international benchmark for PDF quality assurance. The free specifications are utilized 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).
About Universal Proof of Preflight
In Acrobat 9, Adobe was the first to implement the Ghent PDF Workgroup "Universal Proof of Preflight". In supporting this specification, Acrobat 9 further improves communication between designers and production by offering a preflight audit trail. This provides information on whether a preflight has been carried out, which specification was used and what the outcome of the verification was for a specific PDF. In addition, the user can verify whether the file has been altered since the preflight was last executed. The process provides more transparent file exchange and avoids having to preflight files in different stages of the workflow.
