KB380213814: Imaging Engine - Imaging Engine Task results in an error if a font is not embedded

Question

Why is the same file that could be ripped in older Imaging Engine version now ending in an error with unavailable referenced font?

Answer

This is a consequence of a fix, where we intentionally disabled font emulation, because there have been cases where the "font to be emulated" contained characters not available in the "font used to emulate", causing unpredictable/wrong output.
To avoid this "unpredictable output", the font emulation has been disabled from version 22.07 onwards.

Solution

• Make sure all PDFs have the necessary fonts embedded (as specified by the latest PDF standard).

Workarounds

• Force embedding in the workflow, for example with normalization of the file "Export to Normalized PDF (Embed All)".
• "Contourize text" with for example "Optimize PDF" task.
• Re-enable the old behavior for Imaging Engine (not advised, as we cannot guarantee the output).
  You can do this by stopping Imaging Engine (in Automation Engine CFS):
  1. Go to \Esko\bg_prog_pixelmachinectp_v<version>\bin_x64\
  2. Open the JPDeviceCap.jmf file.
  3. Search for the line containing "UseFontEmulation", and change DefaultValue="false" to DefaultValue="true".
  4. Start Imaging Engine again (in Automation Engine CFS).
