The Adox brand name now belongs to Fotoimpex, Berlin. This is why rebranded Ilford films are being sold as Adox CHM 100 & 400
So Fotoimpex are now rebranding some of their other products as well. If you check their site you will find that Adox Fine Print Polywarmtone is actually just a name change for their Classic Arts Polywarmtone paper.
They state: Adox Fine Print Polywarmtone . . . . . . Forte Polywarmton or Bergger CM/CB/CB cream or Moersch Sepia. These Papers are identical in all parameters. (They are referring to emulsion characteristics). So these all come from the Forte factory. Meanwhile EFKE also make paper.
Adox is now the house name for Fotoimpex products.
