ABSTRACT:
Xeroprinting masters are formed by first forming a toner mask. The mask is used to expose a xeroprinting master material exhibiting persistent conductivity in response to a given wavelength and intensity of radiation. The toner mask can be formed and transferred to the xeroprinting material without fusing. After exposure the masking toner can be cleaned off providing a planographic master. Multicolor images are formed by forming two or more masking images, and transferring them to two or more master surfaces. After irradiation and cleaning each master surface is used as a xeroprinting master for a particular color in a multicolor duplicating system.
