Typewriter Ribbon and Carbon Paper Backing

Typewriter ribbons and carbon papers having a backing of santofome paper (polystyrene) exhibit superior transfer image and non-smudge properties.

This paper is hot-melt coated, using a hard doctor blade or drawdown technique. The carbon ink deposited is the medium ink formulation. Since this film has a low softening point, it is particularly suited for a solvent coating system where heat is not used.
