Abstract

A problem encountered with offset printing is that the blanket roller must be cleaned after each new master is employed because a substantial amount of ink remains on the blanket roller after the image is transferred to a receiver sheet. If this ink were not removed, it would degrade the subsequent image to be transferred.

A problem encountered with offset printing is that the
blanket roller must be cleaned after each new master is
employed because a substantial amount of ink remains on
the blanket roller after the image is transferred to a
receiver sheet. If this ink were not removed, it would
degrade the subsequent image to be transferred.

This problem can be minimized or obivated by applying an
ink releasable material to the blanket roller prior to
inking or transfer of an inked image so that substantially all of the ink is transferred to the receiver print so as
to obviate the requirement of cleaning the blanket roller
after every print. Materials which can be employed to coat

the blanket roller are fluids which have a cohesive force
less than that of the ink and include silicone oils, mineral oils and vegetable oils.
