Gcolor Advanced Ingredient Fountain Solution For Offset Printing
Gcolor Fount Xi is a fountain solution for sheetfed offset printing
with advanced ingredient.
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.
About Gcolor Fount Xi
Gcolor Fount Xi is used for sheetfed lithographic printing. The
advanced ingredient provides optimal water/ink balance.
Beside, it contains ingredients for algae and bacteria eliminating
and calcium control, which will prevent crystalisation on rollers
and kill the algae and bateria in the dampening system.
