Abstract: An electrocoagulation printing apparatus has a printing head with an array of electrodes in contact with an electrically conductive electrocoagulation printing ink, and a driver circuit for impressing electric signals to individual electrodes of the array. The driver circuit includes a current limiter for limiting the magnitude of electric current passing through individual electrodes and the electrocoagulation printing ink to a predetermined value. The current limiter corrects a density of adjacent ink film pixels of a printed line to compensate for a cross-influence of impedance between adjacent ink film pixels.

Abstract: A method and apparatus for reproducing an image and transferring same onto a substrate. A positive cylindrical electrode is rotated about its longitudinal axis at a substantially constant speed, the positive electrode having a passivated surface defining a positive electrode active surface. A plurality of negative electrolytically inert electrodes electrically insulated from one another are arranged in rectilinear alignment to define a series of corresponding negative electrode active surface disposed in a plane parallel to the longitudinal axis of the positive electrode and spaced from the positive electrode active surface by a constant predetermined gap, the negative electrodes being spaced from one another by a distance at least equal to the electrode gap to prevent edge corrosion of the negative electrodes. The positive electrode active surface is coated with an olefinic substance and a metal oxide to form thereon microdroplets of olefinic substance containing the metal oxide in an amount to prevent corrosion of the positive electrode. The electrode gap is filled with a colloidal dispersion containing an electrolytically coagulable colloid. Selected ones of the negative electrodes are electrically energized to cause point-by-point selective coagulation and adherence of the colloid onto the olefin and metal oxide-coated positive electrode active surface, thereby forming a series of corresponding dots of colored, coagulated colloid representative of a desired image. The dots of colored, coagulated colloid are then contacted with a substrate to cause transfer of the colored, coagulated colloid onto the substrate and thereby imprint the substrate with the image.

Abstract: A method and apparatus for reproducing an image and transferring same onto an end-use support. A positive electrolytically inert electrode is provided in the form of an endless elongated belt moving at substantially constant speed along a closed horizontal path and having an electrode active surface extending vertically. A plurality of negative electrolytically inert electrodes which are electrically insulated from one another are arranged side-by-side in rectilinear alignment to define a series of corresponding electrode active surfaces disposed transversely of the belt and spaced from the positive electrode active surface thereof by a constant predetermined electrode gap. The electrode gap is filled with a substantially liquid colloidal dispersion containing an electrolytically coagulable colloid, a liquid dispersing medium and a soluble electrolyte and having a substantially constant temperature. Selected ones of the negative electrodes are electrically energized to cause point-by-point selective coagulation and adherence of the colloid onto the positive electrode active surface of the belt opposite the electrode active surface of the energized negative electrodes while the belt is moving, thereby forming a series of corresponding dots of coagulated colloid representative of a desired image. Any remaining non-coagulated colloid is then removed from the positive electrode active surface. The colloid is treated either before or after the coagulation thereof to obtain dots of colored, coagulated colloid which are thereafter contacted with an end-use support to cause transfer of the coloring agent onto the end-use support and thereby imprint the end-use support with the image.
