Abstract
1,253,125. Producing fingerprints electrostatically. KALLE A.G. 4 March, 1969 [8 March, 1968], No. 11480/69. Heading B6C. A method of producing a permanent image of a fingerprint, wherein a fingerprint deliberately made or inadvertently left on a surface other than that of an electrophotographic material is processed by development with an electrophotographic toner, followed if desired, by transferring and/or fixing the resulting image. This method may be used to make positive transparencies for projection purposes.
