Abstract
An example ink cartridge for a stamp may comprise an image-forming component, a first ink-storage component made of an ink-absorbent material, a second ink-storage component made of an ink-absorbent material having one or more channels in it, and a frame made of a rigid, non-ink-absorbent material. The frame may comprise a floor having one or more holes in it. The frame may comprise an outer wall along its perimeter. The outer wall may extend up from the floor such that the outer wall is capable of retaining ink while the ink is being absorbed by the first ink-storage component and the second ink-storage component, thereby increasing the effective volume of the channel(s). The one or more holes may align with the one or more channels such that ink is enabled to flow through the hole(s) into the channel(s).
