A free-flowing powder fountain solution concentrate for use in lithographic printing is provided which comprises at least one of a solid ammonium or alkali metal phosphate, a solid polysaccharide, and a preservative. The powder concentrate's components have uniformly high water solubility as a blend, producing liquid concentrates in excess of 0.7 lbs/gallon of water for ease of use without the need for constant recirculation during storage. A process for preparing a liquid fountain solution concentrate in excess of 0.7 lbs/gallon of water is also provided whereby a premeasured quantity of the powder concentrate is packaged in a moisture proof package to preserve the powder's free flowability prior to use, and prevent exposure to irritating chemical dust during use.
