When editing with Enfocus PitStop, the following warning appears suddenly for PDFs that have been exported from InDesign CC2019:
In November Enfocus will offer multiple dates and times for an online training session about the recently released PitStop 2018.
The webinar is free. However in order to participate you have to pay with your data. Before registration the participants must answer a short survey on the use of PitStop.
On May 26th the General Data Protection Regulation (GDPR) of the EU became effective. Since many visitors of PDF-AKTUELL and also a lot of the readers of the newsletter live in the EU, PDF-AKTUELL is also concerned by this new regulation.
Since the start of this website we are using a double optin for the newsletter subscription. That means that after registration the subscribers gets an e-mail with a conformation link. This prevents that e-mail addresses are subscribed without explicit consent.
Since each subscriber has alread sent his consent I renounce to sending a conformation mail again to all subscribers. Most of you are probably receiving (too) many (mostly unnecessary) mails in this regard these days…
Subscribers of the newsletter can unsubscribe anytime. At the bottom of each newsletter there is also a link to the unsubscription form.
On October 15, 2017 Adobe discontinued the support of Adobe Acrobat XI und Adobe Reader XI. Adobe only supports during five years. That means that Adobe no longer provides technical support, including product and/or security updates, for this version of the application.
However the software can still be used!
According to my survey last year Acrobat XI is the most used Acrobat version by my readers. This is also confirmed by the feedback of the attendees of my seminars.
On February 8th at 14:33:51 (CET) the Adobe preflight signature has expired. That’s why it is no longer possible to embed the preflight audit trail after a preflight with Acrobat Pro in a PDF:
After embedding the preflight results the PDF is usually “sealed” with this generic signature. This allows to recognize immediately if the PDF has been altered after the embedding of the preflight audit trail which may make the results obsolete. Thanks to the signature it is even possible to undo these changes.
Unfortunately the Adobe preflight signature is only valid for 5 years. Therefore the signature has to be renewed during the life cycle of an Acrobat version. Last time the signature expired on 22.11.2012. I remember that day very well. At that time I was responsible for the prepress support at Novartis Pharma and I received the error reports from all over the world. Since embedding the preflight audit trail is mandatory for PDFs for packaging files for Novartis Pharma I had to find a solution urgently. I did found out that replacing the invalid preflight signature of Acrobat 9 and X by the newer signature of Acrobat XI solved the problem.
It took Adobe quite a while to do the same. In January 2013 updates of Acrobat 9 and X containing the Acrobat XI signature were released. This signature was valid until 8.2.2016. It was also delivered with the first versions of Acrobat DC.
But this time Adobe has reacted on time (I have pushed them a little bit). With the January update of Acrobat DC and the 11.0.14 update of Acrobat XI a new preflight signature is installed. Users of these applications only have to perform the free update. Afterwards embedding the preflight audit trail is working properly again. At least until 6.11.2020. Then the signature will expire again…
Since Adobe does not offer updates for Acrobat 9 and X anymore, users of these applications must help themselves.
