Abstract
A process for washing exposed photosensitive resin printing plates to remove uncured resin with a washing liquid, said process comprising a first step in which the washing liquid is sprayed on the surface of the resin plate attached to the surface of a rotary drum while rotating said drum to remove most of the uncured resin, and a second step in which the remaining uncured resin is perfectly eliminated by contacting a rotating brush against the surface of the resin plate on said rotating drum.
Claims16
A process for washing uncured resin from exposed photosensitive resin printing plates by means of a washing liquid, comprising the steps of:
- spraying a washing liquid on a photosensitive surface of said exposed resin plate, said plate being attached to a rotary drum on the drum outer surface, and rotating said drum, thereby to remove most of the uncured resin, and thereafter placing a rotating brush in contact with said surface of said resin plate on said rotating drum, and rotating said brush to remove remaining uncured resin.
An apparatus for washing uncured resin from exposed photosensitive resin printing plates with a washing liquid comprising:
- a washing liquid tank, a rotary drum disposed above said washing liquid tank at a point above a liquid fill point on said tank, said drum having means for holding an exposed photosensitive resin plate on the drum outer surface, a spray means for spraying a washing liquid supplied from said tank toward the surface of said drum, a rotary brush disposed in said tank, and means to move said brush into and out of contact with said drum surface.
