In the printing operation, the printing ink sometimes uneven problem occurs, which is often unbalanced ink control, when a large quantity of small CD printing, pre-press ink, etc., causing uneven. Here we explain how to deal with:
The reasonable control of the amount of water, follow the "ink flood large and small ink small water" principle, the amount of water is not too large, to prevent water ink emulsion Ambassador intensified offset printing, printing ink light dots empty. At the same time the size of the area and distributed on the plate graphic, graphic content and printing speed will also affect the amount of water, in general, graphic area, dense distribution, the printing speed is slow, be necessary to increase the amount of water , whereas decreases. If the water is too large containers, printed materials will be damp, there are traces of water, by increasing the amount of water through the paper version of "aspiration", with white water rolls "wrapped around the water" on the drum, fixed speed water "rejection the "Wipe drum, and other various methods to solve the" big water "problem, none of these lines can also remove the water roll" wiper. " From the plate side, the plate surface fat "Ukraine" All in Print China is not bright, it means that the right amount of water. Add water just under the circumstances, such as a large piece of paper, ink for ink large parts "wrapped ink" whereas small portion of the ink and ink (ink to spread your attention), it should be based on the distribution of pre-press printing surface graphic outlets On the case of the ink in the printing process, metal packaging, should promptly adjust the top wire fountain under local control for the amount of ink, rationally adjust the angle of the ink fountain and ink fountain roller, the overall control for the amount of ink.
