  26. 26. Settings• Will these colors print well on e.g. a Newspaper printing press?
  27. 27. Awareness• Can you visually see the eight major problems in this PDF?
  28. 28. Guts• New technology (often) means new opportunities − Competitive advantage − Faster turnaround, higher Q.• But also possible threaths − Do all the new features really work (e.g. live transparency, PDF layers) − Do they tie in seamlessly with other components of my flow?
  29. 29. Where to begin…
  30. 30. Where to begin…• GWG joboptions and preflight profiles − A set of settings files for many applications to properly create and preflight PDF-files − Tested with more than 200 different compliancy test files − Provided with documentation on how to install and use them − Completely free and downloadable from the GWG website
  31. 31. Where to begin…• Sc
  32. 32. Where to begin…• Ghent Output Suite − Free test suite from GWG − Based on current standards and technology (PDF/X-1a, PDF/X-4) * In the making − Separated in individual categories, important areas to check • Those areas that often cause problems in live situations
  33. 33. Where to begin…• Ghent Output Suite − Created by real people, with real software and representing real situations • Not hand crafted laboratory conditions − Not only for testing RIP’s, but also page layout, imposition, cooking (?), etc.
