WHAT IS WASH??
Wash is a mixture of selected solvents used to remove ink and other impurities from blanket and rollers of printing machines. Recent multi-coloured machines are equipped with Automatic Washup Systems. These systems initiate a process in which wash and water are sprayed on blanket and rollers and cleaning is done by brushing system. The waste generated from this process is automatically drained and collected in containers. Washes come in several varieties. Good grade washes are environment friendly and preserve the properties of rollers and blankets. They are, less hazardous than low grade washes and have less VOC (Volatile Organic Compound). It is due to these advantages, that all leading printing houses invest considerable amount of money in buying good quality wash for their machinery.
CAN YOU RE-USE THE SPENT WASH?
Shimi Research Center has designed a novel process in which spent wash can be recycled. Through this process the impurities present in the spent wash are removed using absorption and microfiltration to ensure the integrity of the original wash. No heating and distillation process is used. The Recovery of wash is in the range of 90-95% depending on the type of wash used. This in turn gives you a saving of upto 35% of your regular expenditure on buying wash.
