Fountain solution
Fountain solution is a water-based mixture specially formulated to dampen lithographic printing plates before they are contacted by the inking rollers. In concentrated form, it is commonly referred to as fountain concentrate, fountain etch, or just etch. Most fountain concentrates today contain synthetic desensitizers. Very few manufacturers still use natural Sudanese gum arabic because of its cost. The term dampening solution is used for the diluted etch.
Fountain Solution Ingredients
Fountain solutions are usually sold as concentrated solutions that are diluted with water to the proper concentration. Most one-step concentrates already contain a natural or synthetic gum, an alcohol substitute, and other essential ingredients, and simply require being diluted with water. With two-step concentrates, the first step generally contains all of the ingredients except the alcohol substitute, with the alcohol substitute added as part of the second step. Although this extra step might be an inconvenience, it permits the press operator to control the alcohol substitute concentration better. The proper mixture of chemicals in the solution is critical for quality printing. Though there may be many chemicals that make up a given manufacturer’s dampening solution concentrate.
