A normalized PDF file is a PDF file that is conform to a set of rules.
One of these rules is having halftone information stored in it's XMP data.
Unfortunately it happens that a normalized PDF file is altered outside your Esko workflow,
where this information is overwritten and causes trouble when importing back in your Esko software.
When opening a Normalized PDF in PackEdge, the following error pops up:
"Missing halftone information in Normalized PDF file. Normally Normalized PDF files always have screening information".
ERROR - Missing halftone information in Normalized PDF File.
What is necessary is for the halftone information to be correctly rewritten in the XMP data of your normalized PDF.
Retrace to where the PDF could have been altered. If for example this has been altered by using Adobe® Illustrator®, note that we have a free and simple solution called the Data Exchange plugin.
Data Exchange Plug-in that acts as a bridge between Adobe® Illustrator® and all Esko applications. You can find the Data Exchange plug-in on our website.
And will solve more than only the "missing halftone information" issue.
