Abstract: An apparatus for manufacturing a display panel includes a printing plate having a plurality of recesses formed on its surface and a hole formed at at least one end thereof, a transfer roller for receiving ink injected in the recesses, a supporting plate for supporting a substrate thereon, wherein the ink from the transfer roller is transferred onto the substrate according to a rotation of the roller, and an ink re-using unit positioned in the hole. Productivity can be improved by reducing a fabrication cost by provision of the ink re-using unit to re-use ink.

Abstract: The invention concerns a pad-printing ink cup fitted with at least one magnet (10). The minimum of one magnet (10) may be positioned at different heights relative to the plane of the doctor edge (22), the magnetic force effective in the said plane depending on said heights.

Abstract: An inking device effective to provide a faultless ink-tight fit comprises a sheet-like support for a plate, and a cartridge, similar in shape to an overturned glass, which is adapted to contain an ink and has a lip in liquid-tight doctoring engagement with the plate, wherein the cartridge has a ring formed from a zirconia-containing ceramic material and provided with a sharp edge constituting the lip.

Abstract: The ink pad replenishing system includes an ink tray containing an ink pad, inlet means for receiving ink and outlet means for providing drainage of excess ink from the ink tray, and an ink reservoir. A first pump is comprised of a deformable and resilient tubular member, and first and second end caps fixably mounted to respective ends of the tubular member, and valve means mounted in the first pump for providing uni-directional flow in a first direction through the first pump upon actuation of the first pump. A second pump is comprised of a deformable and resilient tubular member, and first and second end caps fixably mounted to respective ends of the tubular member, and valve means mounted in the second pump or providing uni-directional flow in a second direction through the second pump upon actuation of the second pump.

Abstract: A printing apparatus is disclosed having stationary frame members disposed at an angle with respect to one another and supporting an ink storage member on one portion while supporting an image carrier member on the other portion. A movable member is capable of rotation and reciprocation, and supports an ink transfer member and a pressure applying member. When in a first angular position, the movable member will bring the ink transfer member and the pressure applying member into operable engagement or position with said ink storage member and said image carrier member respectively when reciprocated between first and second end limits of travel. When the movable member is disposed in a second angular position, the ink transfer member is brought into operable engagement or position with respect to the image carrier means as the movable member is reciprocated between first and second end limits of movement.
