Abstract (en)
[origin: CA1176692A] PHD 81-022 10 11.2.1982 "Method of electrophotographic printing of information". A method of electrophotographic printing of electrically stored information by means of a cathode ray tube. The tube is controlled so that each time only one picture line of the information on the display screen is activated several times in succession. Thus, the transport movement of the record carrier is continuous. The optical system provided between the cathode ray -tube and the record carrier may be constructed to be rigid, so that on the record carrier there is formed an image whose individual pixels represent a small line which consists of several overlapping dots. The necessary brightness is achieved by using a cathode ray tube having a wide display screen on which the picture lines to be transferred to the record carrier are displayed with a 1 : 1 ratio. Furthermore, the display screen is provided with a coarse-grained phosphor of the zinc sulfide type which has a high light yield. Moreover, the line frequency of the cathode beam is increased beyond the customary value in order to counteract phosphor saturation.
