When compared to Lithographic printing Waterless printing saves a significant amount of water, and eliminates the need for other chemicals. The process does not use Isopropyl Alcohol, or fount solutions so there is no discharge of contaminated water to the environment or VOCs to the atmosphere.
A typical B1 press set up for Lithographic printing, operating 16 hours a day will typically use around 150 litres of water a day and around 500 – 600 litres of Isopropyl Alcohol (or substitutes) per month.
Dampening solutions may also need to be disposed of as hazardous waste material.
Printing with UV any curing waterless inks significantly reduces wasted material and also offers the benefit of being 100% VOC free when cured.
Printing with LED-UV waterless inks is environmentally the “best practice” offset printing solution.
