It's a bit old now this question, but I came here via Google, and someone else might also. My solution was to create a Preflight profile (Acrobat 9 Pro) which errored on font information. Clicking on the font name in the results then jumps to the page and highlights the text. Downside is that you get a list of all fonts on all pages organised by page rather than by font name, but it provided a solution for me.
1) Create a new Custom preflight profile
Advanced|Preflight|Options|Create New Preflight Profile
2) Give the profile a name (Fontfinder, say)
3) In the left window of the dialog click "Custom checks"
4) In the right window of the dialog below the blank box click the plus symbol to create a new check and include in current profile
5) Click "text" in the Group, the bottom property is "Text size". Select this and click "Add"
6) The pane below now has more options. Click on the drop down options probably labelled "equal to" and select "less than"
7) Enter a large value in the Number field. I entered 500
8) Top left of the dialog when check fires report as... and enter something like Text size 500 pt or less and click OK. There should be a new custom check in the pane with a red cross beside it. If the cross is not red, click on the check label, and select "error" below the pane
Repeat the steps above for another error check, but changing the option for 500 to "greater than or equal to", and Check fires report as Text 500 pt or greater
9) Click OK in the Edit Profile Dialog
10) Run the profile on your PDF
I set the font to error on a large point size so that all of the errors would report in a group. The second check is simply to catch any font larger than that. I suppose you could check for pt size 50000 and have the same result.
If they are free fonts, you will get them on DaFont. To me, both seem like proprietary fonts, so once you get them downloaded, read on.
Search with the font names the error is showing you.
Once you get the font files downloaded, extract the .zip
if its conpressed.
The font files are in .ttf
format.
Just double click on the .ttf
file and install it. Any other extension also use the same procedure. And restart your Illustrator.
Attaching a screenshot.
Update:
The fonts will remain the same when you open it in Adobe Reader, since the font files are normally embedded in the PDF itself.
Update 2:
I'm attaching the screenshots, of the error msg your getting but will not make any changes to you PDF file if you quit (Assuming you did not edit anything in Illustrator)
If you do make changes, you will get this dialog box while closing the file or quitting Illustrator. Click Don't Save Screenshot below.
If you do not make any changes you will NOT get this dialog, and NO changes will be made to your original file.
Best Answer
That means it is font problem. Try Foxit Reader, it will auto detect and download corresponding font that you needed.
