Abstract
An ink tray has been improved to include a plurality of channel ribs formed on the bottom surface. The rib ends are spaced apart from the ink tray side walls. An ink pad is supported in the ink tray above the channels such that ink directed through the channels is absorbed by the ink pad. Replenishing ink is directed into the ink tray and caused to collect at one end of a first group of channel ribs and thereafter uniformly between each channel rib of the first group. The displaced ink is then caused to uniformly travel between a second group of channel ribs and exit the ink tray. The travel path of the ink allows for even absorption of ink by the ink pad and the removal of excess ink from the ink tray.
