  • INDIVIDUALLY DIVIDED INK DUCTOR ROLLER SYSTEM
    AUTOMATIC INK DENSITY CONTROL BY COMPUTER Automatic ink density control device with new concept.
    Individually divided ink ductor roller is operated by air cylinder and contact time with ductor roller is control by computer.     INSTALLATION EXAMPLE

  • QRD adopt time control system instead of conventional film thickness control system, therefore it has many merits such as enable to adjust ink quantity accurately with 0.1% of notch, needless of Zero-point adjustment, etc.

MERIT OF QRD

  • 1. Time control system

    • Enable to adjust ink quantity accurately with 0.1% notch.
    • Few ink density difference by ink viscosity.
