Unconventional Image Forming Systems in the Graphic Arts - Electrophotography.

Electrophotography has grown in a few years from a laboratory process to a method of graphic reproduction which is now making significant contributions to human communications. Two distinct forms have evolved; a transfer process called xerography employing a reusable selenium photoconductor, and direct processes using zinc oxide and organic photoconductors. The significant applications and equipment described include document copying, offset master making, cathode ray tube recording and microfilm enlarging.
