1. An imaging method which comprises the steps of: (a) forming a grahic image with magnetizable marking materials; (b) magnetizing said graphic image; (c) further developing said graphic image by depositing magnetically attractable marking material on said magnetized image, without having previously fused said graphic image; (d) fixing said redeveloped image to a substrate; and, (e) subsequently polishing said fixed, redeveloped image and utilizing said redeveloped image to provide a latent magnetic image in a magnetic surface without transferring said redeveloped image to said magnetic surface.
