| Abstract: | A new process is described which we have named “Ferrography.” The process enables graphic information to be recorded on magnetic materials and to be reproduced on paper in visual form. Magnetic inks are available in black or colors, enabling monochrome or color reproductions to be made. The magnetic matrix may be used repeatedly so that multiple printing is possible, and the matrix may be stored indefinitely. The process has advantages: economy and speed of operation, permanence of image, and ability to record any information which is available in signal form, such as instrument data, facsimile transmission, or scanned images. |
