    Dear Jack
    Set the ink strip as follows
    Dampening form to Distributor 5mm (without Vario).
    7-8mm (with Vario).
    Dampening form to the plate 4mm.
    Intermediate roller to dampening form roller 2.5mm

    To adjust the dampening distributir relative to the plate dampening roller the width of the contact stripe when operated with vario fonction 7-8 mm or operated without vario fonction 5 mm.
    To adjust the plate dampening roller relative to the plate the width of the contact stripe is 4 mm.
    To adjust the intermediate roller relative to the plate dampening rolller the width of the contact stripe is 3 mm.
    To adjust the metering roller relative to the plate dampening roller this adjustment must be with paper strips .
    For any other question be welcome
