I have an enterprise application that generates reports and one option is to export the report to PDF. The resulting PDFs, when viewed in Adobe Acrobat Pro DC sometimes have overlapping characters. Any ideas on what causes this and how to resolve it?
There are several possibilities here:
(1) The program that generated the PDF file did not embed the fonts referenced by the text in the PDF file. As such, especially if fonts other than Helvetica, Times, Arial, Courier, etc. are used, the substitution fonts may not be able to adequately emulate the original font.
(2) In conjunction with (1) above, if the PDF creation software didn't properly generate font information for the non-embedded fonts, the widths and spacings used when substituting fonts may be very “off” from what is visually pleasing or correct.
