PDF Import adds Black channel to files.


  • There are colorized linked bitmap rasters in the Normalized PDF, when the PDF Import Plug-In is used to open the file as an Esko PDF in Adobe® Illustrator®, it adds a Process Black ink, even though there was not Black in the Normalized PDF.
  • A Normalized PDF that has no Process Black channels in it is opened in Adobe Illustrator with the PDF Import plug-in and the Black channel is added.

What is a Hotfix?

A Hotfix is a software package that you can install on an existing installation of our software. Each hotfix contains fixes for one or more known issues in our released software.

Because there is always a small chance for a hotfix to cause new issues, you should only install Recommended Hotfixes, unless otherwise instructed by your Esko Software Support team.
