Claim One:
1. Electrographic printing wherein raised information, with a distinct tactile feel, can be printed by electrographic techniques, said printing comprising the steps of: forming a desired print image, by a selected electrographic technique, on a receiver member utilizing standard size pigmented marking particles; 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 by the same selected electrographic technique for forming said desired print image utilizing non-pigmented marking particles built up on top of the standard size pigmented marking particles substantially larger size than the standard size pigmented marking particles of the desired print image and fusing the built up toner particles; and wherein one or more electrographic process set-points, control parameters and algorithms, are set to predetermined values when printing tactile feel, raised information so that after the fusing of the built up toner particles form a relief pattern providing a tactile feel and wherein the set-points used when printing the tactile feel raised information are different from electrographic process set-points, control parameters or algorithms, used when printing an image without tactile feel, raised information and wherein the standard size pigmented marking particles have a volume average diameter of less than 9 μm, and the non-pigmented marking particles are on the order of a volume average diameter of 12-30 μm.
