Offset printing Advanced Fountain Solution

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.

Advanced Fountain Solution Features:

·Suitable for various water quality,ink roller surface is not easy to knot calcium

·Has a larger printing tolerance, can keep the stability of the printing effect

·With super hydrophilic effect, can prevent the dirty of non-image area

·Reduce the plate space water,make points clear, full plate printing with high coloring power

·Non-blocking pipe, enhance the ability to sense grease in image area, print quick drying.

Fountain Solution Method of use:

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.
