AI Technical Summary
Traditional flat offset printing requires a large amount of offset printing material, resulting in high production costs and serious environmental pollution.
By combining the release layer with the offset printing process, the release layer, which is formed by thermoforming or vacuum lamination, is bonded to the base fabric to form a non-planar structure, reducing the amount of offset printing material used and improving the adhesion of the offset printing layer by utilizing the surface roughness.
It significantly reduces production costs and environmental pollution, while giving the shoe upper a three-dimensional shape and rich appearance, enhancing user experience and market competitiveness.

Abstract
Claims
1. An upper, characterized by: It includes: Base fabric (1); The isolation layer (2) is formed by bonding a waterproof isolation material to the base fabric (1) and is used to isolate the base fabric (1) and the offset printing layer (3). Offset printing layer (3), wherein the offset printing layer (3) forms a pattern on the isolation layer (2) by offset printing process.
2. An upper according to claim 1, wherein: The isolation layer (2) is formed by either thermoforming or vacuum lamination and is bonded to the base fabric (1) by hot pressing.
3. An upper according to claim 1, wherein: The base fabric (1) is non-planar, and the distance between the highest and lowest points of the base fabric (1) is 1 > H > 0.2 mm.
4. An upper according to claim 1, wherein: The distances from the highest and lowest points of the surface of the isolation layer (2) away from the base fabric (1) after it is bonded to the base fabric (1) are not the same.
5. An upper according to claim 1, wherein: The insulating material is a thin film with uniform or non-uniform thickness.
6. An upper according to claim 5, wherein: The thickness of the insulating material is <1mm.
7. An upper according to claim 6, wherein: The insulating material is a blister film.
8. An upper according to claim 1, wherein: The isolation layer (2) partially covers the base fabric (1).
