Abstract
A single plasma nozzle of a plasma treatment station is used to treat the card surface prior to performing drop-on-demand printing on the card surface. The single plasma nozzle has a plasma discharge width that is less than the width of the card. The card and the plasma nozzle are moved relative to one another using a two direction control scheme during plasma treatment in order to be able to plasma treat a desired area of the card surface. The card and the plasma nozzle may also be moveable toward or away from one another to change the distance therebetween.
