摘要： An electro-coagulation printing apparatus comprises a print head including a drive mechanism having a columnar-shaped anode, which has a horizontally extending, central longitudinal shaft and an anode active surface and is formed by an electro-chemically inactive metal, the drive mechanism serving to revolve the anode about the longitudinal shaft of the anode at substantially constant speed, and a coating device for coating the anode active surface with an oily substance to form micro liquid droplets of the oily substance on the surface, the print head permitting electro-coagulation of colloid, which contains a coloring agent and coagulates electrolytically, to form dots of the coloring coagulation coloid representative of a desired image on the anode active surface coated with the oily substance. The apparatus of the invention further comprises a transfer device for contacting a substrate with dots of the coloring coagulation colloid to transfer the coloring coagulation colloid to the substrate from the anode active surface to thereby print an image on the substrate, and a cleaning device for cleaning the anode active surface to remove the remaining coagulated colloid, the cleaning device being disposed below the anode and the coating device. Such apparatus can print an image of high resolution.

摘要： Electrocoagulation printing method and apparatus are provided which prevents formation of undesirable background (fogging) on electrocoagulation printed images. The apparatus includes: a revolving cylinder (12) formed of an electrolytically inert metal and having a continuous passivated surface (12B) as a positive electrode active surface moving along a predetermined path; an inker (32) which feeds electrocoagulation printing ink for the surface (12B); a printing head (30) for forming on the surface (12B) dots of coagulated ink by electrocoagulation; an oil cascade unit (40) which supplies a first oily substance for the surface (12B) and removes fogging ink mixed with the first oily substance from the surface (12B) without altering the dots of coagulated ink; and a pressure roller (70) which brings a printing substrate (80) into contact with the dots of coagulated ink to cause transfer of the dots of coagulated ink from the surface (12B) to the printing substrate (80). The oil cascade unit (40) allows the fogging ink mixed with the first oily substance to be dislodged from the surface (12B) without altering the dots of coagulated ink, and therefore, formation of an undesirable background (fogging) on a printed images can be prevented.

摘要： An electrocoagulation printing ink which comprises a liquid dispersion comprising a polymer capable of electrolytical coagulation, a liquid medium, a soluble electrolyte, a pigment, and a dispersant for evenly dispersing the pigment in the dispersion, and in which the dispersant is an alkali metal salt of a naphthalenesulfonic acid/formaldehyde condensate; and an electrocoagulation printing method using the same. By using this dispersant, storage stability is improved and undesirable colored scumming formed in the prints obtained by electrocoagulation printing is mitigated. In chemical formula (I), M is an alkali metal and n is an integer of about 2 to about 15.

摘要： A polychromic image is reproduced and transferred onto a substrate (26) by (a) providing a single support member (20) having a continuous surface (32) moving at substantially constant speed along a predetermined path; (b) forming on the surface (32) a colored image with a printing ink containing a coloring agent; and (c) bringing a substrate (26) into contact with the colored image to cause transfer of the image from the surface (32) onto the substrate (26) and thereby imprint the substrate 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 aforesaid path and each using a coloring agent of different color, and to thereby produce several differently colored images which are transferred at respective transfer positions onto the substrate (26) in superimposed relation to provide the desired polychromic image.

摘要： Disclosed are a method and an apparatus for electrocoagulation printing which are improved for rendering the printed ink water-fast. The ink being electrolytically coagulable is electrified, with use of a positive electrode and a negative electrode, and the ink between the positive electrode and the negative electrode is electrolytically coagulated so as to form a dot of coagulated ink for representing the image. The dot of coagulated ink is transferred onto the substrate to represent the image. The dot of coagulated ink is treated with a cross-linking agent to cause cross-link to a cross-linkable component which is contained in the coagulated ink, thereby rendering the dot of coagulated ink water-fast.

摘要： A stabilized electrocoagulation printing ink comprises a liquid colloidal dispersion containing an electrolytically coagulable collloid, a dispersing medium, a soluble electrolyte, a coloring agent and a sequestring agent for complexing metal ions generated during electrocoagulation printing. The sequestring agent is present in an amount to prevent the metal ions from causing the colloid to undergo undesirable cross-linking, without adversely affecting electrocoagulation of the colloid.

摘要： An electrical coagulation printing method and apparatus which prevent an undesirable background (scumming) from forming in an image printed by electrical coagulation. The apparatus comprises a rotating cylinder (12) having a continuous passive surface (12B) which is formed of an electrolytically inactive metal and serves as an anode active surface travelling along a predetermined path, an inker (32) which supplies an electrical coagulation printing ink to the surface (12B), a printing head (30) for forming coagulated ink dots on the surface (12B) by electrical coagulation, an oil cascade unit (40) which supplies a first oil material to the surface (12B) and removes a scumming ink mixed with the first oil material without changing the coagulated ink dots, and an impression cylinder (70) which brings a printing base (80) into contact with the coagulated ink dots and transfers the coagulated ink dots from the surface (12B) to the printing base (80). Thus, since the oil cascade unit (40) removes the scumming ink mixed with the first oil material from the surface (12B), an undesired background (scumming) can be prevented from being formed in a printed image.

摘要： A method and apparatus for coating a metallic substrate (22) with an oily substance. Use is made of a support member (30) having a ceramic coating (70) comprising an oxide ceramic material, onto which is applied the oily substance to form a film of the oily substance uniformly covering the surface of the ceramic coating (70), the film of oily substance breaking down into micro-droplets having substantially uniform size and distribution. The micro-droplets of oily substance are thereafter transferred onto a surface of the metallic substrate (22) without substantially altering the size and distribution of the micro-droplets, thereby coating the surface of the metallic substrate (22) with the oily substance. The invention is particularly useful for coating the positive electrode of a high-speed electrocoagulation printing apparatus with an olefinic substance containing a metal oxide.
