Hi Austin,
I have experienced the same exact issue while i'm my re-writing/re-developing all of my 12-crystal reports in Jasper Soft. Though i have formatted as Calibri font along with BOLD, when i export the report to PDF, i was unable to see them. It appears to me that this is a bug. It's not ONLY me, my entire Development team members (4no's) experience the same issue.
However i managed to figure out the work around for this issue
if you use caliber font - you'll never be able to see bold text in exported pdf.
in order to see the text in BOLD in your pdf copy Please use font named as SansSerif, this will allow you to get BOLD text in your exported pdf.
FYI - we are on Clarity 14.3 & Jasper Soft version is 6.1.0.final
Let me know if you need any further assistance about this issue.Best Regards
Jagadeesh
