摘要： A polychromic image is reproduced and transferred onto a substrate by (a) providing a positive electrode moving at substantially constant speed along a predetermined path, the electrode having a passivated surface defining a positive electrode active surface; (b) forming on the positive electrode active surface a plurality of dots of colored, coagulated colloid representative of a desired image, by electrocoagulation of an electrolytically coagulable colloid present in an electrocoagulation printing ink containing a coloring agent; and (c) bringing an endless belt moving at the same speed as the positive electrode and having on one side thereof a colloid retaining surface adapted to releasably retain dots of electrocoagulated colloid, into contact with the positive electrode active surface to cause transfer of the dots of colored, coagulated colloid from the positive electrode active surface onto the colloid retaining surface of the belt and to thereby imprint same with the image. Steps (b) and (c) are repeated several times to define a corresponding number of printing stages arranged at predetermined locations along the path and each using a coloring agent of different color, thereby producing several differently colored images of coagulated colloid which are transferred at respective transfer positions onto the colloid retaining surface in superimposed relation to provide the desired polychromic image. A substrate is then brought into contact with the surface of the belt to cause transfer of the polychromic image from the colloid retaining surface onto the substrate and to thereby imprint the substrate with the polychromic image.

摘要： 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.
