Emancipation from emulsification

Emulsion is a mixture of ink and dampening solution. In this process, dampening solution is distributed evenly throughout the ink in small droplets. The proportion of water in a “stable emulsion” is around 20%. If higher, then an ink’s splitting properties are reduced, and fluid viscosity is interrupted. As a result, the emulsion becomes unstable, the ink “builds up,” and it “emulsifies.”Too large a proportion of dampening solution in the printing ink or too low a pH value fosters emulsification. Emulsified printing inks lengthen drying times and increase the risk of deposits. Take the following corrective steps:
