Analysis of Effect of Fountain Solution Size on Printing Plate

The balance of the ink and the fountain solution does not mean that the relationship between the printing plate and the fountain solution is balanced. When the amount of the fountain solution is too large, excessive emulsification of the ink occurs, and the dampening solution on the surface of the printing plate becomes excessive. It is a very obvious situation. However, when the fountain solution is only slightly high, the ink will not be emulsified immediately. This is because the more dampening solution is transferred to the ink roller after being absorbed by the printing plate. At this time, the amount of fountain solution on the printing plate is too much, and the amount of printing plate and fountain solution normally used needs to be out of balance. The surface of the printing plate will appear watery at this time, and if the amount continues to increase, the problem of excessive ink emulsification will occur.

The use of a small amount of fountain solution can also cause the imbalance between the printing plate and the fountain solution. The most obvious is that the inorganic salt layer on the surface of the printing plate is not stably enriched and protected, and the metal aluminum is bare and a dirty plate phenomenon occurs. .

A large amount of experience accumulated in experiments and productions proves that: When printing normally, the ink layer thickness of the printing plate is 2~3μm, and when the blank water film thickness is about 0.5~1μm, the ink contains the fountain solution. The volume fraction of 15 to 26%, the maximum does not exceed 30%, basically achieved offset ink balance.
