Fountain Solution Clarification

Lithographic printers can now reduce their costs and improve productivity by using Pall's new Lithopure® Clarifiers. Each Lithopure Clarifier removes contaminants that can cause problems for operators utilizing a recirculating or spray bar fountain solution system. Removing these contaminants will enable lithographic printers to increase press productivity, decrease press maintenance and improve overall print quality. Specific Lithopure Clarifier products designed for individual and centralized recirculators, as well as spray bar systems, are available.

By utilizing Lithopure Clarifiers for recirculating dampening systems, the life of the fountain solution is significantly extended, in turn minimizing waste disposal costs due to less-frequent disposal and decreasing press downtime. Cleaner dampening rollers and fountain solution trays result in decreased hickey defects and less image wear. In addition, since the Lithopure Clarifiers are constructed of ink-(oil-)loving materials, ink emulsification is reduced.

This results in reduced plate scumming and image tinting. The reduction in contamination leads to improved conductivity control of the fountain solution. For spray dampening systems, Lithopure Clarifiers reduce nozzle pluggage.

With the demands on high-quality printing, Pall Lithopure Clarifiers can help you cost-effectively achieve your goals.


Important Facts About Lithopure® Clarifiers

  • Lithopure Clarifiers can enhance your print quality. Lithopure filters remove contaminants that are smaller than the eye can see. These particles can potentially cause defects and wear on printing plates.
  • Lithopure Clarifiers reduce fountain solution consumption and extend the life of the solution by maintaining clean fountain solution in your recirculating system and press pans.
  • By using Lithopure with the continuous flow valve (CFV), you will never starve your press of fountain solution.
  • Lithopure clarifiers reduce production costs due increased press productivity and less press maintenance downtime.
  • Lithopure Clarifiers enhance print quality by reducing plate scumming and tinting, with better conductivity control.
