A method of improving photographic reproductions of a continuously repetitive symmetrical pattern of dots on a photographic plate comprises the steps of photoprinting the image pattern on to a sensitized film; shifting the plate in its plane with respect to the film to a position in which substantially all of the plate pattern overlies substantially all of the previously photoprinted pattern on the film; photoprinting the shifted image of the plate on to the film; and developing the photoprinted pattern on the film. |
