Summary:1489679 Printing INTERNATIONAL BUSINESS MACHINES CORP 15 Oct 1975 [31 Dec 1974] 42146/75 Heading B6C A method of marking a substrate comprises contacting the substrate with a micromist containing magnetically attractable material i.e. a mist whose particle size is such as not to wet the substrate in the absence of an applied magnetic field, and applying a magnetic field pattern to deposit material The micromist may be produced by ultrasonic vibration. The magnetic field may be generated in known fashion by selective heads adjacent the substrate printed on the side opposite the micromist, or by using selectively energizable heads to produce the pattern on a roller or endless band adjacent this side. Alternatively, a magnetized endless band may be exposed to the micromist, and the pattern formed thereon transferred to the final substrate.
