Abstract
There is disclosed apparatus for wetting a roller of a printing system comprising an applicator unit comprising a liquid agent chamber. Upper and lower walls extend from the liquid agent chamber to define a slit therebetween. The upper wall extends beyond a lip of the lower wall to a transfer lip. A flow restrictor is received in the slit to prevent flow of liquid agent to a respective portion of the transfer lip, thereby defining a restricted portion of the slit and an adjacent unrestricted portion of the slit. The flow restrictor fits in the restricted portion with a clearance that permits liquid agent flow at a reduced velocity relative flow through the unrestricted portion, such that liquid agent along the restricted portion is discharged from the lower wall. A method of installing a flow restrictor is also disclosed.
