Description

Technical Field

[0001] The utility model generally relates to the technical field of printing, in particular to a printing substrate. Background Art

[0002] Polyurethane materials (such as artificial leather and synthetic leather) are often used for surface decoration of various products after printing due to their excellent wear resistance, elasticity, chemical resistance and plasticity. However, during the printing process, due to the soft texture of polyurethane materials, there are certain difficulties in material transportation. When entering the printing machine, it often causes downtime and printing interruption, thereby reducing production efficiency. In addition, under normal printing pressure, polyurethane materials may deform, which will lead to inaccurate overprinting and pattern misalignment, and fail to meet the overprinting standards of ordinary paper printing. In order to improve the accuracy of printing, reducing the printing pressure is a feasible solution, but this will bring new problems. After reducing the pressure, although the deformation can be reduced, the printed color will become less bright, prone to color jumping and color change, and poor color stability, making it difficult to meet the color standards of paper printing.

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] Figure 1 A schematic diagram of a printing substrate 100 according to an embodiment of the present invention is shown below. Figure 1 Describe in detail.

[0028] like Figure 1 As shown, the substrate 100 includes a polyurethane layer 110, a reinforcing layer 120 and an adhesive layer 130. The polyurethane layer 110 can be artificial leather or synthetic leather, and the polyurethane layer 110 includes a printing surface 111 and a connecting surface 112, wherein the printing surface 111 serves as an attachment surface for ink during the printing process. The connecting surface 112 is a roughened surface (a surface subjected to a roughening treatment), and its surface is rough and has fluff. The reinforcing layer 120 is disposed on one side of the connecting surface 112 of the polyurethane layer 110, and at least one of the hardness or stiffness of the reinforcing layer 120 is better than that of the polyurethane layer 110. For example, in this embodiment, the hardness and stiffness of the reinforcing layer 120 are both better than those of the polyurethane layer 110. The adhesive layer 130 is disposed between the polyurethane layer 110 and the reinforcing layer 120, so that the polyurethane layer 110 and the reinforcing layer 120 are combined together to form a unified whole. This multi-layered substrate has good hardness and stiffness, good continuity and stability during the printing production process, is not prone to downtime and printing interruption, has higher efficiency, accurate overprinting, clear and delicate patterns, and uniform printing colors. Among them, the adhesive layer 130 is formed by an adhesive, and a suitable adhesive can be selected when making the substrate 100 to ensure that the polyurethane layer 110 and the reinforcement layer 120 can be stably bonded together during the printing process to ensure a good printing effect. At the same time, the adhesive layer 130 can also have the characteristic of being relatively easy to separate the polyurethane layer 110 and the reinforcement layer 120 after printing is completed, so that the staff can easily remove the polyurethane layer 110 from the reinforcement layer 120 to obtain a polyurethane material printed with graphics, which is convenient for subsequent processing.

[0029] According to one embodiment of the utility model, Figure 1 As shown, the reinforcing layer 120 may include a paper layer 121 and a film layer 122, wherein the film layer 122 is formed on one side of the paper layer 121 ( Figure 1 The adhesive layer 130 is disposed between the film layer 122 and the polyurethane layer 110 on the upper middle side, close to the side of the polyurethane layer 110. The surface of the film layer 122 is smooth, so that after printing, the polyurethane layer 110 and the reinforcing layer 120 can be separated relatively easily, which is beneficial to reduce the damage to the polyurethane layer 110 during the separation process, and is also beneficial to improve production efficiency. Optionally, the film layer 122 is a plastic film formed on the surface of the paper layer 121 by a laminating process to ensure the uniformity and adhesion of the film layer 122. Optionally, the thickness of the film layer 122 is set to 0.005-0.1mm, which avoids unnecessary material waste while ensuring the strength of the film layer, and achieves a balance between cost-effectiveness and product performance.

[0030] According to one embodiment of the utility model, Figure 1 As shown, the paper layer 121 is cardboard (such as gray cardboard, white cardboard, etc.). Optionally, the cardboard has a gram weight of 200-400g per square meter to ensure the hardness and stiffness of the substrate 100, so that the substrate 100 is easy to transport during the printing process, and the substrate 100 has good continuity and stability during the printing production process, thereby improving production efficiency and printing quality. In some embodiments, the paper layer 121 can also be kraft paper, etc.

[0031] According to one embodiment of the utility model, Figure 1 As shown, the thickness of the polyurethane layer 110 is 0.3-0.6 mm. Optionally, the thickness of the polyurethane layer 110 is 0.45 mm. Optionally, the thickness of the roughened portion (roughened surface) of the polyurethane layer 110 is 0.1-0.15.

[0032] Figure 2 FIG. 2 shows a schematic diagram of a substrate 200 according to an embodiment of the present invention. Figure 2As shown, the substrate 200 includes a polyurethane layer 210, a reinforcement layer 220 and an adhesive layer 230. The polyurethane layer 210, the reinforcement layer 220 and the adhesive layer 230 can be made of the same or similar materials as the corresponding structures in the substrate 100, which will not be described in detail here. The difference between the substrate 200 and the substrate 100 is that one or more grippers 221 are provided at the edge of the reinforcement layer 220 of the substrate 200, and the grippers 221 are located outside the outline of the polyurethane layer 210. By providing the grippers 221 at the edge of the reinforcement layer 220, it is convenient for the staff to tear the polyurethane layer 210 and the reinforcement layer 220 apart. Optionally, the grippers 221 are provided in plurality, and the plurality of grippers 221 are arranged at intervals on the long side of the reinforcement layer 220 to facilitate the staff to tear the polyurethane layer 210 and the reinforcement layer 220 apart. Optionally, a plurality of grippers 221 are arranged at intervals on each long side of the reinforcing layer 220 , so that the staff can select the starting point for tearing the polyurethane layer 210 and the reinforcing layer 220 according to actual conditions.

Figure 3 As shown, the substrate 300 includes a polyurethane layer 310, a reinforcement layer 320 and an adhesive layer 330. The polyurethane layer 310, the reinforcement layer 320 and the adhesive layer 330 can be made of the same or similar materials as the corresponding structures in the substrate 100, which will not be repeated here. The difference between the substrate 300 and the substrate 100 is that the edge of the polyurethane layer 310 of the substrate 300 is provided with one or more notches 311, and the notches 311 are located within the outline of the reinforcement layer 320. By providing the notches 311 at the edge of the polyurethane layer 310, it is convenient for the staff to tear the polyurethane layer 310 and the reinforcement layer 320 apart. Optionally, the notches 311 are provided in plurality, and the plurality of notches 311 are arranged at intervals on the long side of the polyurethane layer 310 to facilitate the staff to tear the polyurethane layer 310 and the reinforcement layer 320 apart. Optionally, a plurality of notches 311 are arranged at intervals on each long side of the polyurethane-enhanced layer 310 , so that the staff can select the starting point for tearing the polyurethane layer 210 and the reinforcement layer 220 according to actual conditions.
