Grabit is a superior hickey picker roller that solves problems like paper dust, Molleton
fluff and ink scum that causes hickey troubles in offset printing.
Grabit has overcome the weak points of conventional hickey picker rollers which were,
for example, "making life of the plate short due to stiff rubber surface" and "high-cost
of the roller".
1. Structure of Grabit
These rollers are produced with our company technology using an unique blend of elastomer
and cut fiber. The surface is like buckskin which has moderate softness.
a) Fast and effective removal of dusts. Those dusts which adhere on the Grabit will easily come off by automatic cleaning.
b) The buckskin surface is moderately soft and does not harm the plate which makes it longer life.

cleaning will take somewhat longer than normal rollers. Do not use chlorine solvents
such as trichloethane-based or polarized solvents such as MEK.
b) When changing to brighter colors, we recommend removing Grabit roller from the
press, then hand washing and rinsing.
c) Once a month, remove Grabit roller from the press and thoroughly wet the surface
with roller wash, and use a brass brush to remove foreign objects from the surface.
