Abstract
A method and an apparatus for stabilizing a microporous marking structure is disclosed. The method comprises the steps of placing a microporous marking structure in conjunction with an absorbent material within a stabilizing device. A positive pressure is then applied to the microporous marking structure within the stabilizing device until a sufficient amount of ink originally retained within the microporous marking structure is forced to flow therefrom into the absorbent material so that the microporous marking structure obtains a substantially stabilized state. The apparatus may comprise a pair of substantially rigid plates arranged for relative movement with respect to each other wherein at least one of the substantially rigid plates is adapted to support a microporous marking structure thereon until the microporous marking structure is arranged between the plates. The apparatus also includes a pressure generating device for compressing the microporous marking structure between the pair of rigid plates until a desired amount of ink is removed from the marking structure.
