## Abstract

A blanket for transferring a paste image from an engraved plate to a substrate is provided. The blanket includes a foam, a PET layer on the foam, and an paste transfer layer on the PET layer. The blanket has a Tan δ value of 0.05 to 0.13. The foam can be made of polyurethane, polyethylene, nitrile-butadiene rubber, silicone, or a combination thereof. The paste transfer layer can be made of silicone rubber, fluoro rubber, fluorosilicone rubber, a combination thereof, or a multi-layered structure thereof.

## Claims

### Claim 1

A blanket for transferring a paste image from an engraved plate to a substrate, comprising:
a foam;
a PET layer on the foam; and
a paste transfer layer on the PET layer,
wherein the blanket has a Tan δ value of 0.05 to 0.13.

### Claim 2 (depends on 1)

The blanket as claimed in claim 1, wherein the foam comprises polyurethane, polyethylene, nitrile-butadiene rubber, silicone, or a combination thereof.

### Claim 3 (depends on 2)

The blanket as claimed in claim 2, wherein the polyurethane, polyethylene, nitrile-butadiene rubber, or silicone has a weight average molecular weight of 2,000 to 1,000,000.

### Claim 4 (depends on 1)

The blanket as claimed in claim 1, wherein the foam has a thickness of 0.5 mm to 1.5 mm.

### Claim 5 (depends on 1)
