    (54) Low inertia ink ductor


    (57) A printing press ink ductor roll rotates about its axis and moves between an ink fountain roll (65) to pick up ink on its outer surface from the fountain roll and an ink train roll to deliver ink from its outer surface to the ink train roll. The ductor roll comprises opposite journals (11, 12) for mounting the ductor roll for rotation about its axis, a tube (14) attached at its opposite ends to said journals. The tube is a composite comprising 30 to 70% by weight of graphite fibers and 70 to 30% by weight of a thermoplastic or thermosetting resin.
