I am employing a document design program known as H.p Exstream design & Production for years. I recently installed Adobe acrobat professional DC and started getting this error message after opening a PDF.
The font is embedded (I checked) and it’s solely giving the error on this font kind, as all the other fonts i’m using seem fine. The fonts i’m using are proprietary to the corporate. i’m not solely seeing this on PDFs created from my native workstation, however also on PDFs using my design created on the mainframe (zOS)
I have been using these fonts for over a year with no problems. May it’s something in the font, or however the PDF is being created? It’s causing some textual elements on the PDF to disappear. I have read the past questions that are asked on this topic with no clear answer that has helped me.
