摘要:
An apparatus and method for processing a lithographic printing plate is disclosed. The apparatus (10) comprises (i) plate transport means (4, 12, 12') for conveying the plate (14) through the apparatus; (ii) plate detection means (8) for locating the plate in the apparatus and for determining the plate width; (iii) one or more nozzle(s) (20) for depositing developer on the plate, wherein said nozzle(s) are arranged to shuttle over the plate or are arranged as a fixed array that spans at least the width of the plate. The plate detection means are coupled to the nozzles by means for selectively actuating the nozzles that are positioned to deposit developer across the plate area, which results in a significant reduction of developer consumption. In preferred embodiments, the nozzles apply developer in accordance with the image on the plate, which enables an even lower consumption of developer.

Processes are described to remove substances from substrates, for example, electronic devices. In an embodiment, a process may include providing a substrate including a first side and a second side with a substance being disposed on at least a portion of the first side of the substrate. The process may also include contacting the substrate with a solution such that the first side of the substrate is coated with the solution, at least a portion of the second side is free of the solution and at least a portion of the substance is released from the first side of the substrate. Additionally, the process may include rinsing the substrate to remove at least a portion of the substance released from the first side of the substrate. The process may be suitable for removing and, in some instances, completely dissolving photoresists of the positive and negative varieties.

A method of recycling waste liquid from a plate-making process for a photosensitive planographic printing plate that is discharged by a plate-making process for a photosensitive planographic printing plate using a developer liquid for a photosensitive planographic printing plate in an automatic developing machine, includes: replenishing a development bath of the automatic developing machine with a development replenisher liquid without dilution or after dilution of the development replenisher liquid with an amount of water no more than 10 times an amount of the development replenisher liquid in terms of mass, the development replenisher liquid including an organic solvent having a boiling point in a range of from 100°C to 300°C, and a content ratio of organic solvent having a boiling point in a range of from 100°C to 300°C in the development replenisher liquid being in a range of from 5% by mass to 30% by mass; concentrating plate-making process waste liquid, which has been generated during a plate-making process for a photosensitive planographic printing plate in the automatic developing machine, by evaporation using an evaporation concentration apparatus such that a ratio of an amount of the plate-making process waste liquid after the concentrating, to an amount of the plate-making process waste liquid before the concentrating, is in a range of from 1/2.5 to 1/5 in terms of volume, thereby separating the plate-making process waste liquid into water vapor and dissolved components; recovering the separated water vapor from the evaporation concentration apparatus and condensing the water vapor in a cooling means to obtain regenerated water; and using the obtained regenerated water as at least one of diluent water for the development replenisher liquid or rinsing water in the automatic developing machine.
摘要:
A method for processing waste solution in the plate-making process of a photosensitive planographic printing plate, with which the maintenance performance of the equipment is excellent, is provided. A method for processing waste solution in the plate-making process, in which the waste solution in the plate-making process, which is discharged when the plate-making process of a photosensitive planographic printing plate is carried out using a developer for a photosensitive planographic printing plate, said developer being characterized by containing at least one sugar selected from non-reducing sugars and at least one base without containing a silicate and by having a pH within the range of from 9.0 to 13.5, is evaporated and concentrated by an evaporative concentration apparatus, thereby being separated into water vapor and a dissolved component, wherein, the waste solution in the plate-making process is heated by a heating means in an evaporation container that is provided with base resistance, and the water vapor separated from the waste solution in the plate-making process is taken out from the evaporation container and condensed in a cooling means, thereby being turned into reclaimed water.
