Fountain solution definition

Fountain solution means a mixture of water and other volatile and non-volatile chemicals and additives used in lithographic printing operations that maintains the quality of the printing plate including preventing debris build up (e.g., spray power, paper fiber, coating particles, dried ink particles, and other materials), and increases viscosity and reduces the surface tension of the water so that it spreads easily across the printing plate surface. The fountain solution wets the nonimage area so that the ink is maintained within the image areas. Non-volatile additives include mineral salts and hydrophilic gums. Alcohol and alcohol substitutes are the most common VOC additives used to reduce the surface tension of the fountain solution.
Fountain solution means a surface coating applied to the plate roll of an offset lithographic printing line for the purpose of wetting only the nonimage areas so that they are not ink receptive.
Fountain solution means water-based solution that applies to lithographic plate to render the non-image areas unreceptive to the ink.

More Definitions of Fountain solution

Fountain solution means the solution used in certain methods of printing which is applied to the image plate to maintain hydrophilic properties of the non-image areas.
Fountain solution means a water-based material that is applied to the non-image areas of the lithographic plate that were rendered water receptive thus making these areas unreceptive to ink. Fountain solutions have historically contained significant amounts of isopropyl alcohol which serves as a wetting agent or “dampening aid” to enhance the spreadability of the fountain solution across the plate.
