(Calcium Carbonate fillers, lint, coatings) Calcium, paper lint & coating circulate through the fount recirculation system neutralizing the fountain solution, causing plates to become sensitive and the need to increase water speeds to keep plates clean. Calcium build up on the rollers causing roller hardening. This alone causes all over or area specific ink / water imbalances that show up during press runs! All of this shortens the life of fountain solution, creating issues from plate sensitivity, plugging or running at higher water speeds.
