Abstract: An apparatus for removing a film coated on a substrate includes a film removing body including a liquid supply device which discharges removing liquid through a discharge opening to a removal portion of a film coated on a substrate, and a collection device which collects a discharged removing liquid through a collection opening, and an adjustment device that adjusts a distance between a surface of the substrate to a bottom surface of the film removing body at a position between the discharge opening and the collection opening.

Abstract: One embodiment of the present invention is a method for manufacturing an organic electroluminescence device, including forming an organic light emitting layer by a relief printing method, the method including transferring an organic light emitting material ink from an ink supplier to a printing plate, and subsequently transferring the organic light emitting material ink from the printing plate to a substrate, wherein a solvent of the organic light emitting material ink comprises a solvent having a vapor pressure over 500 Pa at 20-25 degrees Celsius, and wherein the time between the reception of the ink by the printing plate and the transfer of the ink to the substrate is equal to or less than 5 seconds.

Abstract: A letterpress printing machine is disclosed including a rotary printing cylinder in which a relief printing plate is installed, a substrate surface plate on which a substrate is placed, an ink supply device supplying ink on the relief printing plate, a relief printing plate washing equipment washing the surface of the relief printing plate, and a wiper for a plate. The relief printing plate washing equipment can include a washing liquid supplying unit, an air blasting unit jetting pressurized gas to the relief printing plate, a suction unit sucking the washing liquid scattered by air blasting unit, and a washing liquid recovery unit.
