Parsing plate version of troubleshooting

Plate fall edition troubleshooting parse plate fall edition troubleshooting

problem initially suspected to be a revision, then to print. Strict operation in the process of plate burning, redesign, ensure uniform layout clean, outlets, but also appeared after computer network version of the phenomenon, just different version of the position and the last time. With a magnifying glass observation fall edition, found around the white point is very neat, graphic and blank parts without transition, to eliminate the risk when plate burning extraction unevenness causing virtual edition. Plate burning, and after the brush glue to observe space, did not appear any situation, then baked version, after baked version put the plate on the light with a magnifying glass observation carefully, we found that there is a dot weak, with the tape after wiping, the results appeared out version of the phenomenon.

according to the above situation, after careful analysis, judgment caused by developer. We use the developer is to use to buy products made from developer directly dissolved in hot water, when the weather turns cold or preparation time is too long, will produce very small particles of sediment. If there are no rinse thoroughly, the enhancement after the particles will stay on the page, in the case of heat or pressure, particle will continue to play a role, make the graphic part dissolve, resulting in the fall edition. In order to confirm this judgment, we again plate burning, washed in the fully developed, with a wet towel to wipe equably again to layout, and then pasting baked version. With a magnifying glass look carefully layout - there are no branches breezing, via computer printing, everything is good, also confirmed our judgment.

analysis the cause of the problem: one is the developer of the preparation time is too long, although the developer has fully dissolved when making up, but due to time is too long, or there will be precipitation phenomenon; Second, the weather gets cold also can cause a precipitation developer; Three is the operator does not completely according to the production process, the enhancement directly after washed, not 2% ~ 3% phosphoric acid solution for fixing processing, thus particles on the layout of exist after enhancement, fall edition phenomenon. Avoid this kind of failure of the method is very simple, actually a developer is don't use to have sediment particles; Second, after the development for fixing, and full of water. According to this method after processing, plate off version of the phenomenon is rare. Conversion table packaging printing knowledge
