Method of delivering a fountain solution

A system for preparing a lithographic fountain solution, comprising:

• a first liquid concentrate comprising one or more film-forming components of the fountain solution, said first liquid concentrate comprising about 10–60% 4w wt film-forming polymer, about 5–50% by wt organic acid, and about 5–50% by wt inorganic acid;
• a second liquid concentrate comprising one or more wetting components of the fountain solution;
• and
• a mixing apparatus structured to continuously meter proportions of the first and second liquid concentrates into a water source.

A system for preparing a fountain solution, comprising the following components packaged together:

• first and second liquid concentrates each separately contained and packaged together;
• the first liquid concentrate comprising one or more water-soluble film-forming polymers at about 10–60% by wt;
• one or more organic acids at about 5–50% by wt, and one or more inorganic acids at about 5 50% by wt;
• and the second liquid concentrate comprising one or more diluents, one or more solvents, and one or more surfactants;
• and
• a metering apparatus operable for delivering a proportion of each of the first and second liquid concentrates into water to form the fountain solution.
