  • Offset printing plate and process for making same
    Patent number: 4431724
    Abstract: An offset printing plate is provided comprising a carbon steel substrate with printing and non-printing areas on its surface. The printing areas are made of a light-sensitive top layer material based on derivatives of ortho-naphthoquinonediazide-sulphonic or carboxylic acids or a light-sensitive top layer material comprising a photopolymerizable composition. These printing areas form a relief over the plate surface. The non-printing areas are made of a hydrophilized metal of the substrate hydrophilized carbon steel.A process for making an offset printing plate comprises application, onto a carbon steel substrate, of a light sensitive top layer based on derivatives of ortho-naphthoquinonediazide-sulphonic or carboxylic acids or a light-sensitive top layer comprising a photopolymerizable composition. The thus-applied top layer is dried.
