Effect of dampening agents on emulsification for lithography ink

Laboratory test method which determines the emulsification rate of dampening solution and ink has been described In lithography using the mutual repellence of oil and water, the emulsification is produced by dispersion of dampening water and ink because of the printing pressure on a practical press. Rheological properties of Ink-Water balance are the important factors in lithographic printing. The emulsification theory and laboratory test method deduced from Surland and Kim. It is shown that the emulfisication curves relate to the rates of change in the emulsifide ink\`s flow properties, to the shear stability of the emulsion formed To study on the factors determining the emulsion velocity, we have measured water pickup and calculated emulsification velocity constant \`k\` and activation energy.
