Abstract
A method and apparatus to ink and dampen a lithographic printing plate including a dampening fluid removal device comprising a doctor blade positioned in pressure indented relation with a resilient inking roller to remove dampening fluid of low viscosity from the roller while leaving more viscous ink on the roller surface. The blade, therefore, is efficient to doctor dampening fluid while insufficient for printing ink.
