A problem encountered with direct printing, or without a blanket transfer roll, is the lack of good, solid area fill~in for the imaged areas. This problem can be minimized or obviated and prints obtained of improved quality in letterpress or planographic direct printing by smoothing the ink on the inked master without smearing the image, after its contact with the form roll and prior to contact with the receiver sheet. The smoothing can be accomplished by the use of an ink releasing roller rotating in the opposite direction of the master cylinder with light pressure so as not to smear the image, said roller revolving at approximately the same speed of the master cylinder. The roller can be rendered ink releasing by dampening with a fountain solution but the fountain solution is applied after inking of the master and not prior thereto as is conventionally employed.
