MAGNETIC PRINTING METHOD AND TRANSFER SHEET FOR DOCUMENTS

摘要

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 Bekk.
