ABSTRACT:
A process of preparing a lithographic printing master is presented utilizing electrophotographic principles. As a result of the high density, low background images which can be developed using the disclosed novel developer composition, a high quality lithographic master can be fabricated. The novel developer composition comprises a low melt viscosity polyamide resin, a magnetic oxide component and a conductive carbon pigment.
