I have this T206 SL Arch Persons card with a P350 back that has all kinds of issues.
- Underlined E in "Subjects".
- Period after "Quality".
- Misc. stray ink spots
Under magnification it all looks to be printed and not added after the fact.
Here's a really large scan to get a better look (view at 100%):

What do you make of it?
Bad day for the printer?
Specific equipment being used was ready to be swapped?
Or opposite and early in the process so excess fresh ink?
