Claims
- 1. A rubber blanket for an offset printing, comprising:
a surface rubber layer; a first fabric layer bonded to the lower surface of said surface rubber layer; a compressible layer bonded to the lower surface of said first fabric layer; and a second fabric layer bonded to the lower surface of said compressible layer; wherein:
the thickness of the blanket falls within a range of between 1.65 mm and 3 mm; said first fabric layer is a plain weave having a thickness falling within a range of between 0.2 mm and 0.35 mm; said second fabric layer is a plain weave having a thickness falling within a range of between 0.35 mm and 0.55 mm, a tensile strength not lower than 50 kgf/cm, and an elongation at break not higher than 7.5%; and said compressible layer has a thickness falling within a range of between 0.5 mm and 2.15 mm.
- 2. The rubber blanket for an offset printing according to claim 1, which satisfies formulas (1) and (2) given below:
- 3. The rubber blanket for an offset printing according to claim 1, wherein the thickness of said surface rubber layer falls within a range of between 0.25 mm and 0.8 mm.
- 4. The rubber blanket for an offset printing according to claim 1, wherein the thickness of said compressible layer falls within a range of between 0.5 mm and 1.1 mm.
- 5. The rubber blanket for an offset printing according to claim 1, wherein the thickness of said first fabric layer falls within a range of between 0.2 mm and 0.3 mm and the thickness of said second fabric layer falls within a range of between 0.35 mm and 0.45 mm.
- 6. The rubber blanket for an offset printing according to claim 1, wherein the tensile strength of said second fabric layer is not lower than 55 kgf/cm.
- 7. The rubber blanket for an offset printing according to claim 1, wherein the elongation at break of said second fabric layer is not higher than 6.5%.
- 8. The rubber blanket for an offset printing according to claim 1, further comprising: a first adhesive layer provided between said surface rubber layer and said first fabric layer; a second adhesive layer provided between said first fabric layer and said compressible layer; and a third adhesive layer provided between said compressible layer and said second fabric layer, wherein a total thickness of said first to third adhesive layers falls within a range of not more than 0.1 mm.
