Liquid photic printing plate repair tips

We often encounter this situation in the production of liquid photosensitive resin plate, table version, line version of the production process is often due to the black tube is too long to cause the individual lamp light is insufficient or the resin photosensitive index is low, resulting in partial exposure Insufficient, so that in the development process there will be thin lines bent or hollow at the root of the line, printing will inevitably lead to a broken line or imprinted directly affect the print quality.

After a long period of exploration and exploration, we have successfully solved this quality problem with a re-supplementary resin repair method. The specific approach is: After the drying liquid plate with a thin needle tip with a little resin carefully smear at the root of the empty line (smear must be uniform), and then exposed again, exposure to observe the layout, if there are false places can be Keep patching until you are satisfied. The same method is used to remedy the slight thin line bending. The liquid resin plate thus repaired can achieve normal quality, which not only wastes the resin caused by re-plating, but also saves time. The above is a little bit of experience we have accumulated in the process of plate making. It is for reference only.
