Environmental control subsystem on the data that can be changed lithographic printing device

摘要

PROBLEM TO BE SOLVED: To provide a method and a structure for minimizing the presence of vapor clouding in the path between energy (e.g., radiation) source and the dampening fluid layer in a variable data lithography system.;SOLUTION: A dry air source includes an air pump (blower) 38 with a desiccator cartridge 40 attached to the pump exhaust, so that the air being pumped out is dried as the air is being provided. This dry air may then be circulated within environmental control subsystem 30, proximate the surface of dampening fluid layer 32, to enhance the evaporation rate of the dampening fluid and reduce the energy requirements on laser patterning subsystem 16.;COPYRIGHT: (C)2013,JPO&INPIT
