  • Methods of making multi-color ink stamps
    Patent number: 7387068
    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.

  • Marking structures for hand stamps
    Patent number: 7273009
    Abstract: A hand stamp includes a first marking structure having a front surface adapted to print a first ink onto an object, a rear surface and peripheral edges extending between the front and rear surfaces. The hand stamp includes a second marking structure having a front surface adapted to print a second ink onto an object, a rear surface and peripheral edges extending between the front and rear surfaces of the second marking structure. The first and second marking structures are permanently assembled together so that at least one of the edges of the first marking structure opposes at least one of the edges of the second marking structure, whereby at least one of the opposing edges has a non-porous surface for preventing migration of the first ink of the first marking structure with the second ink of the second marking structure.
