Hi:

I don't know anything about the Bergger continuous tone film, I myself uses
the BPF 200 panchromatic film, but these are the different types of
Bergger's continuous tone films:

      BPFB-10
      A continuous-tone, orthochromatic film for exposure by contact or
projection. Gradation is medium to hard. Can be used with lith developer.
Comes on a Polyester support of 100µ with an anti-halation backing.

---------------------------------------------------------------------------- 

----
      BPFB-18
      A continuous-tone film identical to BPFB-10, but on a thicker
polyester support of 175µ.

----------------------------------------------------------------------------
----
      BPFO-10
      A continuous-tone, orthochromatic film to be exposed by contact or
enlargement.  Gradation is from medium to hard.  Comes on a polyester
support of 100µ with an anti-halation backing.

      Regards,

      Alejandro López de Haro
