High-Resolution Printing & Touch Panel


  • ●The trial for mass product of Touch Panel by Printable electronics has been requested high-resolution printing.

  • ●Particularly, thin lines which are less than Line/Space=30um/30um are requested around the circumference wiring, and the frame formations which are less than wave 30um are requested in processes of making light blocking layers.(*wave: means polish of frame)

  • ●Thin lines made by our Precision gravure offset printing machine and performances of light blocking layer made by our Ink-jet printing machine are described as following.

    The demand of the accuracy to the circumference wiring pattern has been increasing year after year.

      2013 2014
    Line width
    (representative value)
    30-40um 20-25um
    Layer thickness accuracy ±30% ±20%

    Drawing the thin lines under the 30um and thick lines at the same time in complicated Patterns are requested.

    Line width 35um, continuous printing more than 200 sheets
    (7inch sample continuous printing test in 2013)

    Continuous printing including 30um width thin lines
    and thick lines
