KDF DT-339 offset printing fountain solution

1.no sedimentation,no foam forming 2.extremely low erosion 3.good water-ink balance,clear dot 4.enviromental friendly

 Properties:

a. Have good cushion ability, and stable pH value.It adopts multiple kinds of hydrophilic and water-keeping raw materials for manufacturing.

b. Able to react with non-graphical part of printing plate, and form water-insoluble inorganic salt; Spreading on non-graphical part, moistening ability is high.c. The erodibility against machine and printing plate is extremely low.d. There is no sedimentation, no foam forming, and do not blocking circulation passage.e. There is no phenomenon of leavening or bacteria growing.f. The balance of water and ink is felicitous. There is no piling of ink,and the ink dots are clear.

Points to notice:

The major component of fountain solution is water, and since the hardness of water is varying from different regions.Normally,the conductivity of soft water is within 0-220US, while the conductivity of hard water is set to about 450US to control fountain solution's adding quantity.

The conductivity of clean water should be measured, and the conductivity of clean water should be deducted when there is real application. There is practice proving that controlling the conductivity within 800-1200US, pH value within 4.8-5.3, and the content of 2-propanol within 8%-12%, and not exceeding 15%, the quality of products is more easily controlled.
