ABSTRACT:
The improved method of development is implemented with an automatic processor for developing presensitized offset printing plates with a substantially virgin aqueous solution that contains an alkali silicate and that is supplied for each printing plate, said aqueous solution containing calcium ions in an amount of up to 10 mg/L. The improved developing apparatus comprises a means of mixing a concentrated developing solution with diluent water to prepare a working solution and a means of applying the working solution onto the surface of a presensitized offset printing plate being transported. The apparatus is characterized by further including a mechanism that performs ion-exchange on the diluent water before it is mixed with the concentrated developing solution.
