Each of the inkers comprises an ink metering roller in pressure indented relation with an ink transfer roller having an oleophillic surface, the ink transfer roller being in pressure indented relationship with a single form roller which is in pressure indented relation with one of the printing plates. Each of the dampeners comprises a dampening fluid metering roller in pressure indented relation with a dampening fluid transfer roller having a hydrophilic surface, the dampening fluid transfer roller being in pressure indented relation with the same single form roller such that ink and dampening fluid continuously applied on the single form roller is applied to each of the printing plates.
