E.sun electrostatic assist (including E.sun impression roller) can compensate the intrinsic defects from the gravure printing—a phenomenon that loses the contrast in the paper printing technology. By applying the E.sun assist, a satisfactory and superior printing quality can be achieved. After many years dedicated research and development, E.sun products have been widely used and installed both in domestic and abroad in the gravure printing. The technology, performance and reliability of our products have been proved in the field and our products have been achieved same or better performance over our competitors from abroad. The products have been designed and manufactured to be exchangeable with same category products from abroad. The impression roller, which is the accessory of the electrostatic assist has achieved same or better performance in the electrical and plastic properties over our competitor’s one from abroad.
