Abstract
A roller microcontact printing device and a printing method of the device are revealed. The roller microcontact printing device includes a transfer module with a transfer roller and a supply module. The supply module provides an isolating solution and a thin film material to the transfer module to form an isolation layer and a thin film layer in turn on the surface of the transfer roller. Then the thin film is transferred to a substrate by the transfer roller. The microcontact print device and method are used in a roll-to-roll printing process. Thus the production efficiency of the thin film layer on the substrate is improved and the cost is reduced.
