Abstract: A process of printing ceramic articles simultaneously with electroforming them to produce ceramic articles having patterns thereon comprises preparing a thin flexible diaphragm with a pattern thereon, applying the diaphragm to an electrode, immersing the electrode with the diaphragm thereon in a ceramic slip and applying electric current between the electrode as an anode and a counter electrode to deposit ceramic material on the electrode to form a green ceramic article to which the pattern is imparted by the diaphragm. The electrode with the diaphragm and green ceramic article thereon is removed from the ceramic slip and the diaphragm and article are together removed from the electrode. The article thus formed with the pattern thereon is thereafter dried and fired. The diaphragm is either left on the article and consumed during firing or is removed from the article before firing.

Abstract: In a process and apparatus for producing ceramic tiles, such as wall tiles and floor tiles, including thin tiles of a size up to a square meter, metal electrode plates having thereon three-dimensional design and insulating paint or tape defining the boundaries of one or more tiles to be produced, are transported by a conveyor system through a bath of finely divided ceramic material suspended in an aqueous electrolyte while applying an electric potential between the plates and a counter electrode in the bath to produce electrodeposition of ceramic material from the bath onto conductive portions of the plates bounded by the insulating material. The voltage and time of travel in the bath are selected to produce a deposit of ceramic material with a thickness of from 1 to 20 mm.
