SELECTIVE PRINTING OF RAISED INFORMATION BY ELECTROGRAPHY

摘要

Electrographic printing wherein raised information, with a distinct tactile feel, can be printed by electrographic techniques. Such electrographic printing comprises the steps of forming a desired print image, electrographically, on a receiver member utilizing standard size marking particles; and in an area of the formed print image, where desired tactile feel, raised information is to be formed, selectively forming such tactile feel, raised information utilizing marking particles of a substantially larger size than the standard size marking particles of the desired print image.
