Description

Technical Field

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

[0002] UV printing is a printing process that uses ultraviolet light to dry and cure ink. It requires the ink containing photosensitizer to be matched with UV curing lamp. The application of UV printing is one of the most important contents in the printing industry, and the positioning paper usually has special marks or grid lines to help printers better align and adjust the printing materials, thereby avoiding the offset or misalignment of the printed content.

[0003] In the existing technology, the positioning UV printing paper has color blocks or built-in grid lines used for positioning in the actual printing production process. As the UV ink is curing, the internal components undergo cross-linking and polymerization, and the volume changes instantly to produce large internal stress, which affects the adhesion of the ink to the printing material, making the areas where the color blocks and built-in grid lines have been set more likely to fall off, and it is extremely difficult to change the formula. Therefore, we propose a positioning UV printing paper to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the problems existing in the prior art and proposes a positioning UV printing paper.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A positioning UV printing paper, comprising a paper substrate, wherein a positioning structure is arranged on the paper substrate;

[0007] The positioning structure includes an anti-seepage layer coated on a paper substrate, the paper substrate is also covered with a printing layer, a positioning line is arranged on the lower surface of the printing layer, the positioning line is arranged close to the anti-seepage layer, micropores are opened at positions close to the positioning lines on the printing layer, and the micropores are located in the middle of the anti-seepage layer.

[0008] Preferably, the positioning line is made of a rigid material, and the positioning line is pressed into the anti-seepage layer.

[0009] Preferably, a region of the printing layer close to the positioning line is coated with a positioning color block.

[0010] Preferably, the printing layer is matte paper.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In this utility model, by setting a positioning structure and adopting an anti-seepage layer in cooperation with a printing layer and positioning lines, the positioning lines and the anti-seepage layer can be used as positioning reference points to achieve the purpose of printing positioning. At the same time, during the printing process, a small amount of ink will flow through the micropores to the space between the anti-seepage layer and the printing layer, making the ink have stronger adhesion after UV curing, and the printed pattern is not weaker than peeling off from the printing paper.

[0016] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all the embodiments.

[0017] Referring to Figure 1 - Figure 2 , a positioning UV printing paper includes a paper substrate 1, and a positioning structure is provided on the paper substrate 1;

[0018] The positioning structure includes an anti-seepage layer 2 coated on the paper substrate 1. A printing layer 3 is further covered on the paper substrate 1. A positioning line 4 is provided on the lower surface of the printing layer 3. The positioning line 4 is disposed close to the anti-seepage layer 2. Micropores 5 are formed at a position of the printing layer 3 close to the positioning line 4, and the micropores 5 are located in the middle of the anti-seepage layer 2;

[0019] In the above design, the anti-seepage layer 2 is directly coated on the paper substrate 1 with a seepage-proof coating, so that the paper substrate 1 has seepage-proof ability at this position. The positioning line 4 is annular, further limiting the ink penetration range passing through the micropores 5. When the user uses this positioning UV printing paper, first use the micropores 5 as the positioning origin for printing. When the ink is printed on this positioning UV printing paper, only a small amount of ink can pass through the micropores 5 and penetrate between the anti-seepage layer 2 and the printing layer 3. At the same time, the ink cannot continue to infiltrate downward into the paper substrate 1, ensuring that the back of the paper substrate 1 will not show color. During the UV curing process, not only the ink on the printing layer 3 can be cured, but also the ink between the anti-seepage layer 2 and the printing layer 3 can be cured, and this part of the ink can enhance the adhesion effect between the ink and the positioning UV printing paper, making the printed pattern not weaker than peeling off.

[0020] Furthermore, the positioning line 4 is made of a rigid material, and the positioning line 4 is pressed into the anti-seepage layer 2. In this design, the positioning line 4 is a fiber line with an outer diameter of about 0.01 mm. According to the specific thickness requirements of the positioning UV printing paper, the requirements for the outer diameter of the positioning line 4 can be relaxed. After pressing the positioning line 4 into the anti-seepage layer 2, the surface of the positioning UV printing paper can be ensured to be flat.

[0021] Furthermore, a positioning color block is coated in the area of the printing layer 3 close to the positioning line 4. In this design, the positioning color block is mainly designed according to the positioning requirements of the printing equipment. At present, most printing equipment cannot directly identify the micropores 5, so the positioning color block is set to improve the positioning effect.

[0022] Furthermore, the printing layer 3 is made of matte paper. Matte paper is more widely used in the printing field, and at the same time has better ink adhesion effect. The finished product can also be converted into a bright state by laminating after printing.

[0023] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
