Upcoming webinars:

Ghent Workgroup – general introduction

Tue. 14 November, 2017 at 4pm CET / 10am ET


Since 2002, the Ghent Workgroup (GWG) has been creating best practice specification and foundations for new standards all in an effort to make the global design and publishing processes more reliable and efficient. This introductory webinar will look who we are, what we do, how we do it, and at what some of those best practices are and how you can introduce them into your business processes today!

  • What makes a good PDF file and ensures that it meets your expectation
  • How can you test your workflows to ensure that it can properly process files that meet customer expectations and reduce errors
  • What you can do to get involved in the GWG

9 reasons to preflight

Thu. 16 November, 2017 at 4pm CET / 10am ET

Preflight has been around for many years and has proven its value. However not everybody preflights their PDF’s. The technology is commonly available though, and can save a lot of time and money when used properly. Tune in on this session and quickly learn about:

  • Why PDF preflight is so important
  • Key essentials behind certain PDF features or prefight checks
  • How to use the inevitable Ghent Workgroup ‘9 reasons why you need preflight’ file

PDF2.0 standards – what’s new?

Tue. 21 November, 2017 at 4pm CET / 10am ET


After almost 10 years of work ISO published PDF 2.0 about 4 months ago. The new standard part for ISO 32000 has almost 1000 pages and it’s introduction lists 14 completely new features and 26 which are extended; 22 ‘old’ features have been deprecated. Currently ISO is working on PDF/X-6 which will be based on PDF 2.0. This webinar provides:

  • an overview about PDF 2.0 and the current state of PDF/X-6
  • an introduction into new PDF 2.0 features that are relevant for prepress and print
  • information about when and how prepress workflows should be prepared for these new standards

GWG 2017 PDF Survey Results

Thu. 23 November, 2017 at 4pm CET / 10am ET


The Ghent Workgroup is dedicated to advancing the print, publishing and packaging industries. Our goal is to create practical workflow tools that make daily production tasks easier and faster. That’s why we organized a survey about your PDF workflow. This survey aims to gain insight on today’s PDF use. Further, it wants to discover how well GWG specifications and tools (and other PDF standards) are being adopted and what the worldwide differences are.

The results will help us better understand how processes have changed over the years, which specifications are being adopted, and how workflows vary so we can continue to improve the solutions we offer.

PDF and PDF/X-plus

Wed. 13 December, 2017 at 4pm CET / 10am ET


PDF has been around for quite some time, but it didn’t suddenly fall out of the sky. The introduction of PDF standards is the result of years of negotiation, practical tests and input from many experts in the field. Tune in on this session and learn:

  • why PDF is so important and why we are all using it in our industry
  • the fundamental differences between all these PDF standards in the field
  • the advantages of using the Ghent Workgroup approach

How the Ghent PDF Output Suite can help you to check your output workflow?

Thu. 11 January, 2017 at 4pm CET / 10 am

In this webinar Stephan Jaeggi, co-chair of the GWG Process Control Subcommittee, will present the latest version of the Ghent PDF Output Suite. This is an easy tool to check and finetune a PDF output workflow. During the webinar Stephan will explain the structure of the test patches as well as the amalgated pages and will show how to evaluate the results.

  • learn how to use the Ghent PDF Output Suite
  • know what can be tested with version 5
  • evaluate the results

Processing Steps

Tue. 16 January, 2017 at 4pm CET / 10am ET


It is common practice in the packaging and other segments of the printing industry to work with PDF files that contain both graphics objects that will be used for printing and additional objects that indicate finishing steps e.g. cutting or application of foils. By lack of a standard multiple ad hoc methods are being used and this leads to problems of interoperability between companies and systems. Based on work done in the Packaging Subcommittee of the Ghent Workgroup, ISO 19593‑1 defines standardized mechanisms to store graphics objects and associated metadata corresponding to such finishing processing steps in a PDF file. Adoption of the standard will lead to increased productivity and reduction of errors in the packaging supply chain. This session will include a life demo of products supporting the standard.
Key take-ways:

  • Key concepts in ISO 19593-1 processing steps.
  • How will processing steps improve productivity in the workflow and reduce errors?

PDF for Packaging: The missing piece?

Thu. 1 February, 2017 at 4pm CET / 10am ET


As we continue to look for ways to increase flexibility and reduce time to market, the evolution and transition to digital print is showing promise. However, managing the process of getting the final design to print has still not caught up. Approvals, prepress, print and converting are still following the vendor specific process flows, limiting file exchange across multiple prodcution vendors. The use of PDF in the commercial print and publishing market is now ubiquitous and supports the latest digital print and finishing processes. Following years of research, development and standardization, we are closer to a standardized framework for PDF that helps define settings, rules and workflows. This enables a single PDF that can support the needs of the whole graphic chain including Design, Brand Management, Prepress, Print, and Converting.

  • learn what these developments are
  • learn what you can take advantage of now
  • learn how you can prepare for the future
