1cps to 1000cps. The coating method of microgravure is suitable for thin film coating with low viscosity coatings. The viscosity of the coating liquid suitable for microgravure coating can range from 1cps to 1000cps. Microgravure is a coating method that uses a small-diameter gravure roller. The counter-rotating gravure roller scoops the coating from the liquid supply pan, and a doctor blade scrapes off the excess coating.
