The choice of a cleaning, washing or de-icing solvent will mainly depend on the type of ink used, cellulosic, nitro cellulosic, vinyl PVA, PVB, PVC, polyurethane, acrylic, epoxy, polyester, Plastisol.
During printing, it is necessary to clean the inked parts of the machine or the press, as well as the cleaning of impurities embedded in the blankets, cylinders, and rollers.
In addition, when production is stopped for changing settings, plates, or platemaking, de-icing of blankets in offset and the cleaning of inkwells.
