Abstract

Prints of improved quality are obtained in letterpress or planographic direct printing by smoothing the ink on the master without smearing the image, after its contact with the form roll and prior to contact with the receiver sheet. More particularly, it has been found that the stnoothing results in prints of enhanced image fill-in. This smoothing can be ac-complished by the use of an abhesive roller such as a silicone coated roller with light pressures so as not to smear the image, revolving at approximately the same surface speed as the master cylinder. Further, if the ink is also smoothed on the form roller prior to contact with a master, that the com-bined smoothing procedure, both on the form roller and on the master roller, results in prints of still improved quality.
