What is Fountain Solution?
The dampening system on a lithographic sheetfed press applies a water-based dampening or fountain solution to the Printing plate before it is inked. Dampening Solutions keep the non-
image areas of a plate moistened so that they will not accept ink, and are applied to the entire plate.
The non-image areas of the plate, which are made that way by adsorbing a thin film of gum arabic to them during platemaking, are hydrophilic (water loving) while the image areas are
hydrophobic (water repellent). The desensitizing film on the non-image areas wears off gradually as the plate continues to run on press, so the chemicals in the dampening solution
replenish the desensitizing film. Ink, plate, press speed, paper, temperature, and relative humidity are the principal factors that influence the need for various dampening solutions.
Please use concentration quantitative manage the fountain solution addition. If you choose PH manage and conductivity manage, due to circulating water tank mix into carbon ink acid,
paper powder, powder etc will cause the PH or conductivity fluctuate. Recommended concentration quantitative management without considering external influence,tank circulation is
equipped with filter cotton or fountain plate circulation system,keep the tank clean periodic cleaning.
