Abstract Mobile phones, digital cameras, DVD, PDP, LCD, DMB and other digital consumer electronics market grows significantly, semiconductors and other electronic parts and equipment needs for the manufacturing process has also changed significantly. IC, electronic components, LCD, PDP, OLED, FED, SED, and the display market, in addition to donor-acceptor type of organic solar cells, titanium dioxide, zinc oxide, etc., such as dye-sensitized solar cells and fuel cells, even in the energy sector of the new As the commercialization of the production process closer to the simplification and process are being explored to reduce cost. Production of printed electronics technology can be applied to the case of cleaner production, and increase productivity by reducing process waste from the exposure process and the material cost reductions through cost savings can be used to improve the competitiveness of the product. The process can enable low-temperature plastic substrate, and through it, and so can easily form a large-area thin-film process is made possible. Current specific application (RFID, Display for the C / F, etc.) are being commercialized in a variety of print methods to achieve this is through. Conventional method of forming a conductive pattern usually, but using screen printing, fine pitch screen printing by the limits of the mask pattern is difficult to form, roll-to-roll printing hard for high-speed printing and mass production is difficult . The roll-to-roll printing method as an alternative to screen printing to produce electronic devices by printing techniques that were used traditionally in the latest technology and processing techniques applied to precision control are very economical to implement fine-line printing equipment has been evaluated as . In order to function as electronic devices, especially the dozens of existing micro-level of non-dot print fine line printing is required, the line should not break at all, because according to the specifications required to fit the ink transfer conditions should be established. In this study of roll-to-roll printing conductive paste suitable for gravure offset printing by developing Ag Paste for forming fine patterns to study the basic physical properties with the aim of this study were to.
