Abstract

A method for making high quality color prints is disclosed and basically comprises: providing a hydrophilic plate; magnetizing the plate in an imagewise fashion; depositing magnetic toner contained in a hydrophobic binder on the magnetized plate, thereby providing a lithographic-type master; supplying lithographic ink to the toned plate; and transferring only the ink to a blanket and then to a paper. The provided method overcomes the previous difficulty in magnetographic printing of obtaining colored prints. Previously, transparent dyes could not be used in magnetographic printing due to the fact that the magnetic toner particles were transferred to the paper, and these particles were either black or dirty brown in color.
