ABSTRACT:
A process for producing a printing plate and a printing plate making machine are disclosed. The process involves providing an electrophotographic plate making material which includes a base having a low conductive layer thereon. The material is electrically charged and imagewise exposed. The imagewise exposed material is subjected to liquid toner development with a toner containing a solvent. The solvent is then substantially removed by heating the material to a temperature sufficient to cause the evaporation of the solvent. The material is then moved to a substantially isolated fixing area and again heated in order to fix a toner image on the plate making material. The process can be quickly and easily carried out and eliminates the danger of the explosion of solvent vapors.
