Abstract
A method of electrostatic recording on a cylindrical photoreceptor with a dielectric coating of a photosemiconductor layer is presented. The method includes such main operational steps as charging, exposure and illumination of the photoreceptor, wherein the exposure is carried out by means of optical image scanning along a helix line. This method provides for use of the electrophotography for production of PCBs and printing matrices.
Claims23
A method of electrostatic recording of original information, the method comprising the following steps:
- (i) creating a latent electrostatic image of the original information on a cylindrical photoreceptor with a dielectric coating, the creation of the latent electrostatic image comprising:
- (a) charging the photoreceptor;
- (b) exposing the photoreceptor by means of an optical scanning of the surface of the photoreceptor along a helix line;
- (c) discharging the photoreceptor in darkness;
- (d) performing flood illumination of the photoreceptor;
- and
- (ii) developing the latent electrostatic image, and
- (iii) transferring the developed image onto a final information carrier.
