PDF standards explained: with a focus on the newest


The PDF format is one of the most widely used formats in the world. The numerous functions it has to offer indeed makes the format complex. Many companies use it to exchange information between business partners or in-house. It therefore makes sense to use quality specifications to ensure interoperability within and outside a company. Standard formats defined for PDF can be used to define such quality requirements and simplify their compliance. They also relieve the burden of technical details and help clarify responsibilities within the process chain. ISO defined these standards to guarantee reliable PDF processing in view of the many PDF creation programs and the central importance of PDF. Let’s have a look.

Publish smart – The Internet Standards Series


Most publishers today do not stick to a single format or communication channel. You can choose between the World Wide Web (HTML, CSS, JavaScript …), apps (mostly PDF or proprietary page based formats) or paper (PDF). Publishing houses selling their content are usually using a variety of formats to reach as many (paying) customers as possible. Other 'publishers' who are not earning money with this might want to avoid the necessary efforts. In this article, we want to talk about an example where the internet community came up with a smart solution for digital publications, namely their standards.

Managing manufacturing information with PDF


In the manufacturing industry, the importance of 3D data has recently grown. In light of this, the PDF Association - along with the 3D PDF Consortium - has recently published a high-level introduction about the roles and capabilities of PDF technology in manufacturing industries. With the availability of the necessary technology for the visualization of such 3D data, this technology is used to avoid loss of information in production, scholarly publishing, in situ publishing of 3D figures and much more! Check callas’ view on the matter in this blog post!

EDuCation 2019


I am just back from the PDF Association’s annual event, the EDC (Electronic Document Conference), in Seattle. In short: I think it was a very good event and I am happy that we decided to have it in North America this year. (That’s a picture of Mount Rainier in the blog post cover, taken from Lake Washington during the evening boat tour.) It is always helpful to talk about recent PDF developments and to hear what others, end users as well as developers, think about those. One thing that we (the attendees) came back to various times during the event is that PDF has many more features than currently being used and that it is important to educate users and developers – which made for the title of this blog post. Part of that mission is that from now on, this annual event will alternate between Europe (next year) and North America.

How accessible is the documentation these days?


For people with physical disabilities, such as severely impaired vision, reading on a computer with technical aids is much easier than reading on paper. It therefore makes sense to make technical documentation available electronically, and thus make it accessible to as many people as possible. Guess which is the preferred format for achieving this and how does it add value for everyone?

The future of documents


At the DocEng conference, I met a lot of academics and professionals discussing interesting requirements and solutions related to PDF documents. It was impressive to see what these people are working on, what they (don't) know about PDF and whether it works according to their needs. Here is my experience ...

Can a PDF easily comply to PDF/A, PDF/X and PDF/UA?

Universal key

One of the questions that have been discussed at the recent PDF Days was whether a PDF can comply to more than just one ISO standard. Some of the attendees seem to have been confused by the amount of different standards. I guess it is a legitimate question why we have so many different standards and how difficult it would be to create a PDF that complies with more than just one of them. So, I wrote this blog.
