The skirmishes are everywhere – roller glazing and stripping, white blankets, pH and conductivity drift, plate blinding and picture framing. Calcium buildup problems are popping up all over the pressroom. Sometimes it is only a little flare up like plate blinding, quickly taken care of by replacing the plate. But other times it is an all-out war with buildup on rollers and blankets causing poor print quality and lost press time.

In lithographic offset printing it is necessary to keep the non-image areas of a plate moistened with water so that they will not accept ink. During platemaking these non-image areas are desensitized, usually with a thin absorbed film of gum Arabic and desensitizer so that they prefer water instead of ink.

Alcohol replacers were developed and generally accepted into use in the 1970’s as a replacement for isopropyl alcohol in the press ready mixture. Alcohol replacers, like isopropyl alcohol, are used in combination with a fountain concentrate to deliver a very thin and even water film across the plate surface on continuous type dampening systems. Many printers choose to eliminate the major disadvantages of isopropyl alcohol, including its health and environmental concerns, the increased cost of constant replenishment and its flammability.
