Abstract
A method of making an ink stamp includes providing a first porous structure having a top surface, a bottom surface and porous edges extending between the top and bottom surfaces, loading a first ink into the first porous structure, and providing a second porous structure having a top surface, a bottom surface and porous edges extending between the top and bottom surfaces. The method includes loading a second ink into the second porous structure, applying energy to one of the porous edges of the first porous structure to transform the porous edge to an edge having a non-porous surface, and assembling the first porous structure with the second porous structure so that the non-porous edge of the first porous structure is in direct contact with one of the porous edges of the second porous structure. The non-porous edge prevents the first ink from passing through the non-porous edge to the second porous structure.
