Indirect printing apparatus employing printhead for depositing a sacrificial coating composition on an intermediate transfer member and method for depositing the sacrifical coating

摘要

An indirect printing apparatus can include an intermediate transfer member, at least one jetting nozzle of a printhead positioned proximate the intermediate transfer member for jetting sacrificial coating composition droplets imagewise onto the intermediate transfer member, a drying station, at least one ink jet nozzle positioned proximate the intermediate transfer member, an ink processing station, and a substrate transfer mechanism. The drying station can be configured for drying the sacrificial coating composition to form a sacrificial coating pattern on the intermediate transfer member. The at least one ink jet nozzle can be configured for jetting ink droplets onto the sacrificial coating formed on the intermediate transfer member. The ink processing station can be configured to at least partially dry the ink on the sacrificial coating formed on the intermediate transfer member. The substrate transfer mechanism can be configured for moving a substrate into contact with the intermediate transfer member.
