Highlights:

  • It will increase archival permanence by protecting emulsions
  • Resin-coated Prints require alum hardening to prevent scratching
Full description

User Ratings & Reviews:
The Sprint Record Alum Hardening Converter is used to convert record speed fixer into a hardening fixer or a block stop bath into a hardening stop bath.
  • It is used in the fixer for black and white films and prints
  • The alum hardening strengthens the emulsion and makes them resistant to abrasion and water absorption
  • If the emulsions are not hard, then they can be scratched easily when wet and absorb moisture when dry
  • The Sprint Record Alum Hardening Converter in the fixer also shields emulsions and thereby enhances the archival permanence
  • This alum hardening when used with resin-coated prints, avoids scratches, and offers hard gloss on glossy finish papers
  • It can be used with fiber-based prints when the emulsion is soft and prints need to be dried on hot drums
  • Fiber prints do not require hardening emulsions, as they are already hardened by heat, light, and air while manufacturing
