PrintOnline relies on the PDFX-ready standards rather than its in-house standards for ad production. When it comes to handling digital ad data, the Schlieren-based company PrintOnline has, from the very beginning, tried to encourage data suppliers to use existing and up-to-date technologies. However, not all «roadmaps» could be implemented as desired. The company’s managing director, Kurt Obrist, openly admits this: «The plan was for senders of digital ads to leave the image data used in the ads in the RGB color space and link it to a corresponding ICC profile. The recipient was supposed to perform the corresponding color separation.» This workflow would have required broad acceptance of the RGB color space among both the senders and the recipients of the data—but the graphic arts industry is struggling with this. «Advertisers want to perform the separations themselves,» Obrist knows from experience. «And the recipients don’t want to take responsibility for this process.»
Aiming for PDF/X-3 Based on the Extended PDFX-ready Standard When it comes to the PDF format, PrintOnline relies on PDF/X technology for the electronic exchange of advertisements. Not least to help the PDF/X-3 format (ISO standard PDF/X-3:2002) gain wider acceptance, an association was founded in early 2005 by key players—including Ugra, the industry association VSD, Adobe, and PrintOnline.
The PDFX-ready association, chaired by Kurt Obrist, has become well established. The creation of PDF/X-3 files in accordance with X-ready specifications is gaining increasing popularity—not only among those who send and receive advertisements, but also in commercial printing. Thanks to X-ready, PrintOnline benefits from the fact that data senders can now base their work not on their «in-house standard,» but on a more broadly supported set of rules defined by PDFX-ready.
«To put it simply, the goal of PDFX-ready is to create a clean PDF—based on PDF/X-3. The settings we’ve published are more comprehensive than PDF/X-3 because we’re convinced that this ISO standard alone isn’t sufficient,» explains Obrist. In his view, while the PDF variant X-3 does ensure reliable output, it is the X-ready criteria that additionally guarantee quality. To establish these quality standards on a broad scale, PDFX-ready—through PDF expert and X-ready member Stephan Jaeggi—is even contributing to the Ghent PDF Workgroup, the international counterpart to PDFX-ready. «The goal,» says Obrist, «is a global PDF-based data exchange standard. Through PDFX-ready, we can actively contribute to this.»
Cutting Off the Branch You’re Sitting OnBut isn’t PrintOnline cutting off the branch it’s sitting on by advocating, via X-ready, for a PDF/X that’s easy to create and process—and that also meets its own quality standards? Obrist says no: «Of course not, because verifying PDF data is just one aspect that we cover as an ad hub. With Poldirect, we primarily operate a portal that enables the timely processing of ads. Moreover, even with widespread acceptance of PDF/X-3, the problems associated with data exchange haven’t gone away.»
Obrist is referring to the poor image resolutions, missing control elements, and so on. «New software versions—and soon PDF/X versions as well—are released regularly, and these need to be tested and used to develop the templates. So we won’t be running out of work when it comes to data validation anytime soon.»
Specifically, PDF/X-4 and—already—PDF/X-5, the successor formats to the PDF Exchange Format, are set to be released: «PDFX-ready will provide the corresponding settings as soon as they are approved by the ISO.» PDF/X-5 is expected to make it possible to integrate future ICC profiles stored on a central server. Who knows—maybe we’ll finally see a breakthrough in the RGB workflow after all.
PDFX-ready PDFX-ready is an association.
Founded in early 2005 by various partners from the graphic arts industry, X-ready quickly established itself. As of the end of September 2006, the association had approximately 260 paying members. Companies can obtain certification as PDF creators (Creator Classic), and their employees can be certified as Creator Classic Experts. On the recipient side, PDFX-ready distinguishes between printing companies and publishers that process pure four-color data (Output Classic CMYK) and those that also process data with spot colors (Output Classic Spot). In addition to paying a membership fee, senders must pass an online test, and recipients must print special test forms. An «Output Classic Expert» test is currently under development. Future Challenges: The unique selling point of the PDF format could soon be challenged by Microsoft when it comes to outputting digital print templates. In addition, AdsML (see Werbewoche 31/2006) is knocking on the door. We asked Kurt Obrist about the potential of these emerging technologies.
WW: In addition to new versions of PDF/X, a new standard is emerging in the form of the AdsML XML vocabulary. To what extent are you following this standard? Kurt Obrist: Actively and very closely. Together with Christian Rohrbach of iWare, I represent Switzerland’s interests in the AdsML Consortium. WW: How do you assess AdsML? Kurt Obrist: We view AdsML as a trailblazer in ad delivery because we believe that standardization is also necessary on the administrative side. Fortunately, AdsML does not have to be implemented in its entirety; implementing just parts of it is sufficient. The recently launched AdsML 2.0 version allows for this modular approach. This means AdsML can likely be put into practice soon, moving beyond its theoretical framework. Personally, I’m particularly interested in the «Material Delivery» module, which includes electronic data delivery. WW: What is the goal of the emerging AdsML standard? Kurt Obrist: The entire process of booking, payment, and data transfer can and should be automated as much as possible. Specifically, advertisers or advertising clients can use this standard to compile the correct orders with the corresponding invoices—and for the ad recipient or publisher, the advertising documents can be linked to the corresponding orders. WW: A new document format is set to be integrated into the upcoming Microsoft operating system, Vista. How do you assess this technology, known as XPS (XML Paper Specification)? Kurt Obrist: Once XPS can actually be printed, it could flood our market. I suspect, however, that this new document format will be underestimated by our industry at first. But perhaps XPS will initially serve only as an intermediate format for generating PDF documents. After all, documents prepared in this way will still need to be verified and distributed.
