SMEs in Printing Industry Today have been well developed. It was growth significantly at Indonesia. Many new comers with SMEs scale focus on packaging industry, seems like home industry with limitation machine resources and budget. These researches try to develop and utilize some small machine that big industries just throw it. Based on SMEs capacity and budget, HAMADA is suitable for their production. This machine is small, low electricity consumption, cheap and easy to operate it. However this machine have weakness in oscillating ink roll system. This weakness of this machine made this machine not possible produces high quality full color printing (CMYK). Although this machine rolls system suitable with full color print, it couldn't optimal in full color print. This system model of oscillating is hanging on the top of frame. It without any lock up and adjuster, just put on the top. When the diameter of roll reduces, or the connecting shaft vibration, it give impact with the quality of printing itself significantly become worse. So in other hand this machine could not print in full color (separation). Hamada is good machine, usually it used for monochrome print, for the SMEs need, this machine should be capable to separation print (full color). We try to develop and innovate this oscillating roll system, with some research in order to improve this machine capability and value. This system development help the SMEs could production and print in high quality as the Market needs. Hopefully with this new system development, this machine can help and increase SMEs printing quality and this machine itself become more valuable.
