Description

TECHNICAL FIELD

[0001] The utility model relates to paper surface decoration technical field, especially a printed matter of first pressing and then printing. BACKGROUND

[0002] First pressing and then printing is a surface decoration process widely used in packaging, labels and high-end printed matter. This process mainly includes two steps: first, using a gold pressing device, under the dual action of high temperature and pressure, the gold foil is accurately transferred to the surface of the paper, forming a pattern or text with metal luster, adding unique texture and visual appeal to the product; then, printing on the surface of the paper after gold pressing, further adding other colors or text information, making the product present a more rich and three-dimensional visual effect, thereby improving its overall quality and market competitiveness.

[0003] In practical application, this surface decoration process often encounters the problem of gold loss. This not only seriously affects the printing quality, but also may cause damage to the gold pressing pattern, thereby reducing the aesthetic and service life of the product. The reason is that the surface of the gold foil is usually smooth and has strong chemical inertness. After gold pressing, the Darcy value of the paper surface is significantly reduced, making it difficult for printing ink to adhere firmly to the paper surface. In the subsequent printing and use process, gold loss (ink and gold pressing material falling off the paper surface) is prone to occur.

[0004] Currently, the industry usually uses methods such as increasing ink viscosity, adjusting printing pressure, and using special ink to improve adhesion, but the effect of these methods is often limited and it is difficult to fundamentally solve the problem of gold loss.

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] Figure 1 A schematic diagram of a pre-stamped and post-printed article 100 according to an embodiment of the present invention is shown. Figure 2 An exploded view of a pre-stamped and post-printed printed matter 100 according to an embodiment of the present invention is shown below, in conjunction with... Figure 1 and Figure 2 Provide a detailed description.

[0033] like Figure 1 and Figure 2 As shown, the printed matter 100 includes paper 110, a hot stamping layer 120, a laminating layer 130, a base coat 140, and a printing layer 150. The paper 110 can be coated paper, for example, 128g / m². 2 The paper 110 is coated paper. In other embodiments, the paper 110 may also be offset paper, card stock, newsprint, writing paper, etc., but this utility model is not limited to the above-mentioned paper 110 type. The paper 110 has a first side ( Figure 2 (upper side) and second side ( Figure 2 (The lower side of the middle).

[0034] The gold stamping layer 120 is arranged on the first side of the paper 110, and specifically, the gold stamping layer 120 can cover the entire area of the first side of the paper 110, or can only cover part of the area of the first side of the paper 110, and the specific scheme can be determined according to actual needs. The gold stamping layer 120 can be formed by using a gold stamping device (for example, a gold stamping machine) to perform gold stamping processing on the first side of the paper 110. In the process of gold stamping processing, the gold stamping material on the gold stamping belt is completely and uniformly transferred to the surface of the paper 110, so that a high-quality gold stamping effect is achieved, and the paper 110 is endowed with unique texture and visual appeal.

[0035] The film coating layer 130 is arranged on the surface of the gold stamping layer 120, and specifically, the film coating layer 130 can cover the entire area of the gold stamping layer 120, or can only cover part of the area (the area that needs to be printed) on the gold stamping layer 120. By arranging the film coating layer 130 on the surface of the gold stamping layer 120, the gold stamping layer 120 can be firmly fixed on the surface of the paper 110, so as to avoid the gold stamping material (the gold stamping layer 120) from falling off.

[0036] The base oil layer 140 is arranged on the surface of the film coating layer 130, and specifically, the base oil layer 140 can cover the entire area of the film coating layer 130, or can only cover part of the area (the area that needs to be printed) on the film coating layer 130. The printing layer 150 is printed on the surface of the base oil layer 140 and presents a predetermined pattern. By arranging the base oil layer 140 on the surface of the film coating layer 130, the surface adhesion of the film coating layer 130 can be enhanced, so as to provide high-quality surface conditions for printing of the printing layer 150, to ensure firm adhesion of the ink, and effectively avoid problems such as ink falling off, discoloration, or blurred printing.

[0037] The above describes an embodiment in which the gold stamping layer 120, the film coating layer 130, the base oil layer 140, and the printing layer 150 are sequentially arranged on the first side of the paper 110. Those skilled in the art should understand that in other embodiments, these layers can also be sequentially arranged on the second side of the paper 110. In addition, the gold stamping layer 120, the film coating layer 130, the base oil layer 140, and the printing layer 150 can also be sequentially arranged on both the first side and the second side of the paper 110.

[0038] According to an embodiment of the present application, as shown in Figure 1 and Figure 2 The gold stamping layer 120 is formed of a gold stamping material, and can present a pattern with metallic luster on the surface of the paper, so as to endow the paper with unique texture and visual appeal.

[0039] According to an embodiment of the present application, as shown in Figure 1 and Figure 2As shown, the film coating layer 130 can include a glue layer 131 and a film 132, wherein the glue layer 131 is arranged between the film 132 and the gold stamping layer 120. The glue layer 131 can be formed by glue coating of the paper 110 by a glue coating unit (glue coating roller, etc.) of a film coating device, wherein the glue coating amount is 3-8 g / m 2 , and the glue coating thickness is 5-8 μm, which can ensure that the glue layer 131 has sufficient bonding strength, maintain the overall flexibility of the paper 110, and avoid potential problems such as prolonged drying time, increased cost, and potential problems in subsequent processing caused by excessive glue. The film 132 can be attached to the surface of the glue layer 131 by a film coating unit of the film coating device and be firmly bonded by the glue layer 131. The film 132 can be a matte film, such as a BOPP (Biaxially Oriented Polypropylene) matte film. Such a film 132 has good flexibility, wear resistance, and excellent optical properties, and can give the product a low-gloss, soft, and delicate surface texture, and can cooperate with the gold stamping layer 120 to achieve unique visual appeal. Those skilled in the art will readily understand that the selection of the film 132 is not limited to this. Other types of ready-to-coat films (such as glossy films, frosted films, pearl films, or anti-counterfeiting films, etc.) are also applicable, and these ready-to-coat films generally have specific chemical and physical properties that can significantly enhance the water resistance, oil resistance, or further optimize the printability of the surface of the paper 110, thereby meeting diverse application requirements.

[0040] According to an embodiment of the present application, as shown in Figure 1 and Figure 2 , the base oil layer 140 can be formed by base oil coating of the paper 110 by a coating device, wherein the base oil coating amount is 1.8 g-2.5 g / m 2 , which makes the base oil layer 140 not only provide sufficient dyne value (greater than or equal to 38), but also avoid problems such as prolonged drying time or increased cost caused by excessive coating amount. Preferably, the base oil has a light transmittance greater than or equal to 92%, thereby reducing the influence of the base oil layer 140 on the visual effect of the gold stamping layer 120. In a specific embodiment, the base oil can be a high-adhesion water-based base oil. Such a base oil can be stably combined with the film coating layer 130, significantly improve the dyne value (i.e., adhesion) of the paper 110, thereby providing better surface conditions for subsequent printing, ensuring firm adhesion of the ink, and effectively avoiding problems such as ink peeling, fading, or blurred printing.

[0041] According to an embodiment of the present application, as shown in Figure 1 and Figure 2As shown, the printing layer 150 can include a white ink layer 151 and a pattern layer 152, wherein the white ink layer 151 is printed on the surface of the primer layer 140, and the pattern layer 152 is printed on the surface of the white ink layer 151 and presents a preset pattern. Specifically, the white ink layer 151 is formed by printing white ink on the surface of the primer layer 140, and its shape and size are basically consistent with or slightly larger than the preset pattern, thereby providing a uniform white background for the preset pattern, blocking the color penetration of the gold stamping layer 120, avoiding the interference of the gold stamping layer 120 on the color of the preset pattern, ensuring the clear and accurate color presentation of the preset pattern, and achieving the ideal printing effect. In addition, the presence of the white ink layer 151 can also enhance the overall visual effect of the pattern, make the pattern more prominent, and improve the aesthetic appearance of the printed matter 100. The pattern layer 152 is formed by printing preset ink on the surface of the white ink layer 151, and the color of the preset ink is determined according to the design of the preset pattern. Preferably, the white ink and the preset ink are LED-UV inks, which have good adhesion and rapid curing ability, can be rapidly cured under ultraviolet irradiation, are conducive to improving printing efficiency, and ensure the stability and reliability of printing quality. Preferably, the coverage of the white ink layer 151 should be greater than or equal to 90%, which means that the white ink layer 151 can cover more than 90% of the color of the underlying gold stamping layer 120, thereby preventing the color of the gold stamping layer 120 from interfering with the preset pattern through the white ink layer 151.

[0042] Compared with the prior art, the embodiment of the utility model provides a printing matter 100 which is printed after gold stamping, solves the common gold falling problem in the traditional printing after gold stamping process. Specifically, the present application can firmly fix the gold stamping layer 120 on the surface of the paper 110 by setting the film layer 130 on the surface of the gold stamping layer 120, thereby avoiding the falling of the gold stamping material (gold stamping layer 120). By setting the primer layer 140 on the surface of the film layer 130, the surface adhesion of the film layer 130 can be enhanced, thereby providing more excellent surface conditions for subsequent printing, ensuring the firm adhesion of the ink, and effectively avoiding problems such as ink falling, fading or blurred printing. By setting the white ink layer 151 on the surface of the primer layer 140, and then setting the pattern layer 152 on the white ink layer 151, the interference of the gold stamping layer 120 on the color of the preset pattern can be avoided, the clear and accurate color presentation of the preset pattern can be ensured, and the ideal printing effect can be achieved.

[0043] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments.
