Abstract
A variable lithographic inking system includes a chamber blade system configured to supply ink to an anilox member of an inking system. The inking system includes a soft ink transfer roll and a hard form roll. Ink is transferred from the anilox roll to the form roll by way of the transfer roll, and from the form roll to a reimageable surface layer of an imaging member of a variable data lithographic system. An ink layer free of ink history is uniformly applied onto a surface of the form roll, and subsequently transferred to the reimageable surface layer while avoiding or substantially eliminating image ghosting related to inking non-uniformities.
