Abstract:
A method for forming a tactile printed image on a receiver medium using an electrographic printer, comprising forming a sequence of toner particle images on one or more primary imaging members, the sequence of toner particle images including a plurality of annular shapes having associated inner and outer sizes. The inner and outer sizes of the annular shapes varying in a monotonic sequence, such that when the sequence of toner particle images are transferred in register onto the receiver medium the annular shapes are substantially concentric and overlapping, thereby forming a tactile image feature having a hollow core; which is then fixed to permanently attach the transferred toner particle images to the receiver medium.
