Our members made PDF Week Prague a great success
The PDF industry’s technical conference, PDF Week provides an opportunity for cross-pollination, networking and shared experience across PDF’s ecosystem.
The PDF Association sends a big thank you to all our members who participated (in person or online) in PDF Week Prague 2024, which ran from November 4-8.
We had many great discussions, not only in the meeting room but in early-morning walks through Prague’s foggy streets and over dinner in Prague’s many fine restaurants. 32 attendees were also fortunate enough to participate in Prague’s Invisible Exhibition and Invisible Dinner, simulating the experience of blindness. This event is highly recommended to all, and was of special interest and value to the many members of the PDF Association who work on accessibility for PDF technology.
In particular, the PDF Association expresses its appreciation to Charles University's Faculty of Mathematics and Physics for hosting us, and to Board member Roman Toda, without whom PDF Week Prague 2024 would not have been possible.
