Abstract (en)

[origin: CA1205687A] METHOD AND PAPER FOR PRINTING BY MAGNETOGRAPHY AND DOCUMENTS PRINTED ON PAPER OF THIS TYPE A method for printing by magnetography under atmospheric conditions of relative humidity exceeding 65 or even 75 % consists in transferring to a sheet of paper a fusible magnetic ink in powdered form which is distributed on a temporary magnetizable support in accordance with the configuration to be produced, whereupon the ink is fixed by fusion on the sheet of paper. The paper has a surface resistivity of at least 1010 ohms square and a relative smoothness of at least 20 Beck.
