I ask for your help.

At the start I have a searchable pdf file where Adobe correctly finds cases of “font is italic” during Preflight check.

I do need to run a Ghostscript processing of these files to embed postscript fonts which are used in original file. For this matter I use a command quoted below.

After the execution I do have I file with necessary fonts embedded, but Preflight check produces “No problems found” and no instances of italic text are highlighted in the Preflight report. Which is interesting, text is shown correctly with italic should I copy the text from postprocessed file in Adobe to buffer and insert it to text editor (Word in my case).

So my question is. What happens to hidden text layer that I can’t run Preflight check anymore? What should be done to preserve this possibility?

Wish you a lucky day!
