Caution with new SVG fonts
in Adobe InDesign CC2019

18. January 201931. December 2018 by Stephan Jaeggi

Encouraged by a post in the german PublishingBlog about the new SVG fonts in Adobe InDesign, I have executed some tests myself with the Adobe font Trajan Color in InDesign CC 2019 and have discovered some strange things in the exported PDF/X-4 file:

The OpenType font is converted to a Type3 font during export.

Solution for PDF/X export problem
in Adobe InDesign CC 2019

19. November 201824. October 2018 by Stephan Jaeggi

In some situations the export options for PDF/X-3 and PDF/X-4 in InDesign CC2019 (and also older versions) are no longer active (gray) and the color profiles for output cannot be changed anymore. Therefore, it’s no longer possible to export PDF/X-4 files!

It seems the reason are problems with the synchronizing color settings using Adobe Bridge CC2019.

First update for Acrobat DC 2019
with important bug fix

9. November 20189. October 2018 by Stephan Jaeggi

Adobe has already released an update to version 19.008.20074 for Acrobat DC 2019 some serveral bug fixes.

In the area of print production an ugly bug was fixed which caused rounding errors for color values (percentages) in color separations in the output preview. Some of the values were more than 1 percent to low.

An old bug where values between .51 and .64 are rounded down is still present.

Users of the Output Preview should install this update immediately.

One year PDFX-ready Online Tools

26. October 201726. October 2017 by Stephan Jaeggi

In the morning of Octobre 26th, 2016 we have launched the PDFX-ready Online Tools. which I had developed for PDFX-ready. Right at the beginning we offered three tools:

PDF Preflight (with the well known PDFX-ready preflight profiles)
Color Preflight (Analysis of the undefined color spaces in a PDF)
ISO<–>PSO Converter (for color transformation between the old and new offset standards)

There is a FREEWARE and PREMIUM versions for members of PDFX-ready.

The experience we made in the past year is pretty good. The Enfocus Switch server with the applications Callas pdfToolbox and ColorLogic ProfileTagger is running very stable. But of course there were a few problems.

Quality loss after color conversion
in Acrobat

17. October 201717. October 2017 by Stephan Jaeggi

In preparation of my new seminar PDF Color Management I have tested the image compression before and after color conversion in the most popular PDF tools.

In highend PDFs destinated for quality printing the images are usually compressed using JPEG maximum quality. Before color conversion the images must be decompressed and afterwards compressed again. Acrobat always uses JPEG medium quality for this recompression. The consequence is that there is an (unexpected) loss of quality of the color converted images (see table).
