The text-based PDF comparison PDiff is available in the new version 3.0. The software from CSci is a modern solution for professional document comparison. The new release makes PDF comparison even more powerful thanks to an improved GUI.
PDiff shows all text differences between two PDF documents – as a comparison of the two PDFs and with markings of the deviations. So you can check intended revisions quickly and find unintended changes at first glance:
In the past couple of weeks I have reported several times on problems for display and output of OpenType SVG fonts with Adobe InDesign CC2019:
The Callas Blog has published an article about the necessity of «context aware” preflight. The new «Sifter» technology in Callas pdfToolbox 10 allows to analyze PDF objects in their context. See also my article A Quantum Leap in Preflight!.
Akash Choudhary describes some use cases in his post. The classic example is certainly small black text that is set to knockout:
If the black text is places over a colored background (left), overprinting is important to prevent white flashes in case of register inaccuracies in the printing machine. If the text has no background (right), it does not matter whether it is set to overprint or knockout.
As reported recently the PDFX-ready Online Tools are discontinued per 25.10.18 12 p.m..
Here are some alternative solutions for all users missing the PDFX-ready Online Tools:
- PDF Preflight can be performed identically with the preflight profiles from PDFX-ready for Adobe Acrobat Pro (and Callas pdfToolbox). The only difference is the preflight report which had some additional information about the PDF and a much nicer design. Responding to serveral demands PDFX-ready made available the template of the enhanced Preflight report for download for users of Callas pdfToolbox.
- For Color Preflight there is unfortunately no alternative solution. We have used DocBees Profile Tagger from ColorLogic for this task in the Online Tools. Because of low sales ColorLogic has decided to stop development and sale of the software. In case of interest please contact ColorLogic directly.
- The ISO<–PSO Converter was using the DeviceLink profiles from the European Color Initiative. Those can be downloaded for free from the download page of ECI. They can be used with all tools which can execute DeviceLinks (e.g. Callas pdfToolbox Desktop and Server, Enfocus PitStop Pro and Server, ColorLogic ZePrA).
