Chemical-free Dampening System Ladybird Model 801

What is “Chemical-free Dampening System”?

Dampening water is used in the conventional lithographic printing process. The water involves Isopropyl Alcohol (IPA) or the substitute: the fountain solution. IPA is a VOC (Volatile Organic Compounds) and it is unhealthy to the operator and the environment. Fountain solution is the chemical additives to control the water’s surface tension but it produces water pollution when it is discharged as industrial waste water. Both IPA and the fountain solution are detrimental to the environment. The “Chemical-free Dampening System” is the new printing process that does not use any agent with the dampening water.

How does “Chemical-free Dampening System” work?

The surface tension prevents water from being used as the dampening solution. The fountain solution reduces the water surface tension and improves ink viscosity, but it also makes the ink transfer worse and increases the ink drying time for the printed papers. With this new chemical-free printing device, the water’s surface tension is reduced without any additives. Only ordinary tap water is used as the dampening solution.
