Abstract
An ink jet printing apparatus and method for ink jet printing is described. The apparatus includes an ink reservoir for containing a water based ink and a moisture barrier positioned between the ink in the ink reservoir and ambient air. The moisture barrier is formed of microencapsulated water beads adapted to provide a sustained release of the water into ambient air.
