ABSTRACT:
A facsimile security system includes a base sheet capable of having confidential information thereon and a cover sheet with imprinting thereon for obscuring the confidential information on the base sheet. The imprinting comprises lines in a repeated pattern over the cover sheet and the lines are separated by spaces without imprinting which spaces extend across the cover sheet or in an elongated direction of the cover sheet. The spaces may extend in a diagonal direction on the cover sheet or the spaces may extend only partially across the cover sheet in a repeated pattern. The cover sheet is preprinted in a preferred form of the invention.
