Abstract

Disclosed is a method for forming composite images in a photoelectrophoretic imaging system. P~ccordingto this method, a film containing image information is associated with one of the transparent conductive electrodes of a photoelectrophoretic imaging system. The film is placed in contact with one of these electrodes along the surface opposite the surface of the electrode in contact with the dispersion of electrically photosensitive particles.

Disclosed is a method for forming composite images in a photoelectrophoretic imaging system. P~ccordingto this
method, a film containing image information is associated
with one of the transparent conductive electrodes of a
photoelectrophoretic imaging system. The film is placed
in contact with one of these electrodes along the surface
opposite the surface of the electrode in contact with the dispersion of electrically photosensitive particles.

Image information is thereafter projected through the film containing the image information and the conductive
electrode onto the photosensitive dispersion thereby
resulting in selective migration of the photosensitive
particles in conformance with the projected image infor~
mation and in conformance with the image information on
the film contiguous with the transparent electrode.

This method provides a simplified system for identification
and/or labeling of polychromatic reproductions. Of course,
the film could periodically be advanced in registration
with the advancement of the photosensitive dispersion
through the imaging zone of the photoelectrophoretic
imaging device and thus provide for sequential labeling
or numbering of each subsequent reproduction.
