Abstract: A mountable cylindrical printing blanket apparatus for use with an off-set printing press is provided. The printing blanket has an inner carrier sleeve layer; a printing blanket affixed to the sleeve with at least one compressible layer having a first porosity, at least one printing face layer, a gap extending axially along the mountable printing blanket and having between about 0.2 millimeters and about 2 millimeters in width and a depth substantially extending through at least one layer; and a compressible sealant therein in an amount sufficient to substantially fill the gap. The compressible sealant has a second porosity and a compressibility in both the radial and the tangential direction such that the compressible sealant has a compressibility greater than the compressibility of the compressible layer.
