ADJUSTING THE INK ROLL ECCENTRIC
As soon as you can see complete ink coverage on the die faces, stop rotating the eccentric. Proper adjustment
will normally be reached when the reference line on the Eccentric is somewhere between the 2 and 3 dial
position.
This adjustment procedure brings the Ink Roller into contact with the surface of the Transfer Roller which in turn
applies the ink to the face of the printing dies. Do not rotate the Ink Roll Eccentric Knob further than necessary
towards the “MAX” position or the excess contact pressure will squeeze ink out of the ink roll and may cause
dripping inside the cover.
With the printing dies installed on the print drum,
manually rotate the print drum continuously in one
direction while slowly rotating the Ink Roll Eccentric
Adjusting Knob “A” from the “MIN” towards the
“MAX” position. Turn the Eccentric Knob in small
increments and observe the face of the printing dies
for signs of ink between each adjustment.
1- With the Printing Dies installed on the print drum, rotate
the print drum to a position where the printing dies will
contact the transfer roll. Then loosen the position adjusting
knob and move the transfer roll into contact with the face
of the printing dies. Tighten the position adjusting knob
when the transfer roll contacts the face of the printing die
with just enough pressure to fully ink the die face.
The transfer
roll should never be positioned so close
that it compresses the face of the printing dies.
ADJUSTING THE TRANSFER ROLL / DIE FACE CONTACT PRESSURE
The pressure the transfer roll exerts on the face of the printing dies should be just enough to rotate the transfer
roll and completely ink the face of the dies as they pass during printing. Excessive contact pressure will cause
smudging of the impression, and restriction of the print drum rotation.
