ABSTRACT:
A compressible printing blanket and method of manufacture, in which the blanket has at least one base fabric layer, an elastomeric face, and an intermediate compressible layer. The compressible layer is formed of a microporous material having cavities with interconnected passages. The material is made by admixing particles of hydrated magnesium sulfate in an elastomeric matrix, creating a blowing effect, and leaching the particles from the matrix.
