ABSTRACT OF THE DISCLOSURE A smash-recoverable printing blanket having a substantially uni- form thickness and method of making the same are provided. The blanket comprises a plurality of layers including at least one layer which swells upon being contacted by a liquid. A plurality of microcapsules are dis- posed within the blanket, with the microcapsules containing the liquid. The microcapsules are ruptured upon smashing the blanket. This releases the liquid contained therewithin against the one layer thereby causing swelling thereof and restoring of the adjacent layer substantially to its original position prior to the smashing, in order to define the uniform thickness. Thus, when the blanket is subjected to excessive compression or shashing, it is self-recovering. In other words, the construction of the blanket is such that it restores itself to its original thickness, without stopping or removing the damaged blanket or stopping the associated printing apparatus or press.
