Abstract
A master is formed on a photoconductive surface by first forming an electrostatic charge pattern on the imaging member and developing the charge pattern to form an image of electroscopic marking particles. The developed image is uniformly coated with a thin layer of an adhesive coating and the coated image is then contacted with an adhesive surface transfer element. Upon separation the thin layer of adhesive overcoating fractures. The thin overcoating over the electroscopic particles and these particles transfer to the transfer element so as to leave on the photoconductive member the remaining thin overcoating layer in an image configuration which constitutes the master. The master can be used to make copies by electrostatic, lithographic or gravure printing.
Claims14
A method of forming a master on a photoconductive surface comprising:
- a. forming an electrostatic charge pattern on the surface of a photoconductive imaging member;
- b. applying a xerographic developer to said member bearing the charge pattern to form an image composed of electroscopic marking particles;
- c. uniformly coating said particles and said member with a thin layer of an adhesive coating;
- d. contacting said coated member with an adhesive surface transfer element and separating said transfer element whereby the thin layer of adhesive overcoating fractures with the electroscopic particles and the associated overcoating being transferred to the transfer element to leave remaining on the photoconductive member said thin layer in the noimage areas to form a master.
