Printing plate producing method applying liquid photosensitive resin bag, and apparatus thereof

Abstract

The invention relates to a printing plate producing method of a liquid photosensitive resin bag capable of free packaging and free batching, and an apparatus thereof. A transparent bag body is selected according to the formation specification of a printing plate and is provided with at least one open lateral edge. Liquid photosensitive resin with proper amount is filled in the transparent bag body and obstructed from flowing towards the unsealed lateral edge by using a thrust rod capable of free rolling or sliding. In the process of planishing the liquid photosensitive resin, the liquid photosensitive resin can freely flow towards the unsealed lateral edge and simultaneously push the thrust rod to move outwards till the flowing is naturally stopped. The apparatus for realizing the printing plate producing method consists of the transparent bag body, a lower transparent clamping plate, a thickness gauge, an upper transparent clamping plate, a light source and the thrust rod. The apparatus can avoid the problem that in the prior art the thoroughly-sealed and quantificational liquid photosensitive resin cannot correctly match with the specification of the printing plate and leads to waste; and the apparatus can simplify the production process of the printing plate and a printing plate producing apparatus and is beneficial to improving the printing plate production efficiency.

Description

Technical field: [0001] The invention relates to printing plate-making technology, in particular to a non-precoated plate-making method using liquid photosensitive resin curing technology, in particular to a printing plate manufacturing method and equipment for free-packaging and free-quantitative liquid photosensitive resin bags. Background technique: [0002] In the prior art, the plate-making work of converting the negative film into a printing plate includes two methods: pre-coated and non-pre-coated. The pre-coated plate-making uses a formed resin plate with fixed length, width and thickness as the printing plate. The basic plate of the plate is made on the resin plate with the same pattern as the negative film through exposure, plate washing and other procedures, so as to obtain the printing plate; instead of pre-coating plate-making, the liquid photosensitive resin is used as the raw material. The liquid photosensitive resin is formed into a fixed length, width and th...

Problems solved by technology

[0004] The object of the present invention is to provide a printing plate manufacturing method of a liquid photosensitive resin bag that can be freely encapsulated and quantified freely, and the printing plate manufacturing method of the liquid photosensitive resin bag that can be freely encapsulated and quantified freely will solve the problems in the prior art. The resin in the liquid photosensitive resin bag is pre-quantified, which cannot accurately match the specifications of the printing plate, resulting in waste of technical problems
