SYSTEMS AND METHODS FOR FACILITATING MAGNETIC INK CHARACTER RECOGNITION (MICR) IMAGE FORMING USING DIGITAL OFFSET LITHOGRAPHIC PRINTING TECHNIQUES

摘要

A system and method are provided for producing Magnetic Ink Character Recognition (MICR) characters on image receiving medium substrates using a variable digital data offset lithographic architecture which provides for varying lithographic images between cycles of a marking device. MICR inks are provided with a solid particle magnetizable pigment components in a proportion of at least 20% by weight suspended in solution in the ink composition. MICR inks are provided with a solid particle magnetizable pigment components having particle sizes in excess of one micron suspended in solution in the ink composition. The disclosed systems and methods provide for MICR characters to be formed on an image receiving medium substrate over background images applied using other inks in a single device, and/or in a single pass of the image receiving medium substrate through the device.
