Manufacturing of printed electronics using printing technology has begun to get into the hot issue in many ways due to the low cost effectiveness to existing semi-conductor process. This technology, with low cost and high productivity, can make it possible to produce printed electronics such as TFT, solar cell, RFID Tag, printed battery, and so on. In this study, apparatus of gravure-offset printing are developed for fine line-width/gap printing and the results obtained from the apparatus shows that it is possible to make around 20 micro-meter line-width/gap printing patterns. The roll-to-roll printing system for fine line-width printing based on primary experiment is presented. The printing results obtained from the system shows around 30 micro-meter line-width/gap printing patterns.
