Abstract
A printing blanket construction is provided which includes a reinforcing fabric ply comprised of a weft insertion fabric or a heavy gauge fabric, where the reinforcing fabric ply provides all of the necessary tensioning properties to the blanket. The use of the reinforcing fabric ply eliminates the need for additional reinforcing fabric plies in the blanket construction, and provides high tensile strength, low stretch, and resistance to gauge loss.
Claims19
An offset printing blanket construction comprising:
- a smooth printing surface layer for transferring ink from a printing plate to a substrate, said printing surface layer positioned on a single woven reinforcing fabric ply selected from a weft insertion fabric ply having a denier of at least 1000 or a heavy gauge fabric ply having a gauge of between about 0.020 and 0.040 inches (0.05 to about 0.10 cm), said reinforcing fabric ply having a tensile strength of greater than about 250 lbs/in. (446.5×102 g/cm), said single reinforcing ply providing all tensioning properties to said blanket.
A printing blanket construction comprising:
- a printing surface layer adapted to transfer ink from a printing plate to a substrate, said printing surface layer positioned on a single reinforcing fabric ply comprising a weft insertion fabric ply comprising a polyester yarn having a denier of at least 1500, said reinforcing fabric ply having a tensile strength of greater than about 250 lbs/in. (446.5×102 g/cm), said reinforcing fabric ply providing all tensioning properties to said blanket.
An offset printing blanket construction comprising a smooth printing surface layer for transferring ink from a printing plate to a substrate, a compressible layer and a single woven reinforcing fabric ply having a tensile strength greater than about 250 lb/in. (446.5×102 g/cm) selected from a weft insertion fabric ply and a heavy gauge fabric ply, said single reinforcing ply providing all tensioning properties to said blanket.
