 From my discussions of various films on other forums I think this is
a quality control issue. Quality control may also be an issue with
the films made in Croatia, such as Efke PL 25 and PL 100, but Efke PL
100 is otherwise just an outstanding film for alternative printing.

As for the specific surface imperfections you describe, I don't
believe I have hear them mentioned before.
