This paper is related to a roll-type micro-contact printing process. The proper parameters such as coating velocity, inking velocity, printing velocity and printing pressure as well as Ag contents of Ag ink were extracted to perform the fine patterning of Ag electrodes. Additionally we developed a process for PDMS with high uniform thickness. Finally, we obtained the Ag fine electrodes on $4.5cm\;{\times}\;4.5cm$ plastic substrate with the line width of 10 um, thickness less than 300 nm, surface roughness less than 40 nm, and the specific resistance of $2.08\;{\times}\;10^{-5}{\Omega}{\cdot}cm$.
