Then, the metallic ink is printed on the substrate through a printing plate using a color group on the printing press. Each color group can only print a single metallic color, and the process is complicated. Summary of the invention

[0014] In one embodiment, before the step of printing the preset target image on the target inkjet printing substrate in a digital color printing manner to obtain the target pattern print with a metallic texture, the step further includes:

[0015] Apply an adhesion enhancer to the surface of the target inkjet-printed substrate.

[0016] In one embodiment, the adhesion enhancer is a lacquer oil coating liquid.

[0038] like Figure 1 As shown, a digital printing method with a metallic texture is provided, comprising:

[0039] Step 110, using a preset adhesive spray agent to spray-paint on a preset substrate surface according to a preset target graphic shape to obtain a preliminary spray-painted substrate.

[0040] In this step, a preset bonding spray agent is used as a spraying material and needs to be sprayed on the surface of a preset substrate. When spraying, it needs to be done according to a preset target graphic shape. The preset target graphic shape is the graphic shape of the subsequent target printing. By spraying on the surface of the preset substrate according to the shape of the preset graphic within its shape outline, a foundation is laid for bonding other substances to the area within the subsequent preset target graphic shape.

[0041] In one embodiment, the preset bonding spray agent is UV adhesive oil or UV resin oil, and the preset substrate is coated paper.

[0042] In one embodiment, Figure 2 As shown, the preset bonding spray agent 30 is sprayed on the surface of the preset substrate 20 according to the preset target graphic shape using the spray head of the digital cold stamping machine 10 to obtain a preliminary spray-painted substrate. Figure 2 The vertical arrow in the diagram indicates the spraying direction.

[0043] Step 120 , performing primary curing on the preliminary printed substrate to obtain a preliminary printed substrate after primary curing.

[0044] After spraying the preset bonding spray agent on the surface of the above-mentioned preset substrate, a preliminary sprayed substrate is obtained. Since the bonding between the preset bonding spray agent and the preset substrate surface is not very strong at this time, further curing treatment is required to make the preset bonding spray agent and the preset substrate surface more tightly bonded.

[0045] In this step, the preset adhesive spray after spraying is initially cured through the initial curing treatment, and the degree of curing is about 60% to 80%.

[0046] Step 130 , laminating the preliminary printed substrate after the initial curing to the preset metal foil film to obtain a laminated printed substrate.

[0047] In this step, when the preset metal foil film is laminated to the primary printed substrate after the initial curing, the preset metal foil film is laminated only in the area where the preset adhesive spray agent is sprayed, thereby obtaining the laminated printed substrate.

[0048] In one embodiment, Figure 3 As shown, the preset metal foil film 60 is a silver foil film, and the preliminary spray-painted substrate 50 after the initial curing is laminated with the preset metal foil film 60 by a pressure roller 40 to obtain a laminated spray-painted substrate.

[0049] Step 140 , secondary curing the bonded inkjet substrate to obtain a secondary cured inkjet substrate.

[0050] In this step, after the initial curing is completed, the preset bonding spray agent is only preliminarily shaped. After obtaining the bonded spray-painted substrate, the area of ​​the above-mentioned preset bonding spray agent bonded to the preset metal foil film can be completely cured, that is, the above-mentioned preset bonding spray agent is completely shaped and combined and fixed to the surface of the above-mentioned preset substrate in combination with the bonded preset metal foil film.

[0051] Step 150 , removing the redundant preset metal foil film in the inkjet printing substrate after secondary curing to obtain the target inkjet printing substrate.

[0052] like Figure 4 As shown, the excess metal foil film 90 in the secondary cured inkjet substrate 80 is removed by a separation roller 70 to obtain a target inkjet substrate, on which there is an adhesive spray layer in a preset target graphic shape, and a metal foil film layer is attached to the adhesive spray layer.

[0053] Step 160 , printing the preset target image and text on the target inkjet printing substrate in a digital color printing manner to obtain a target pattern print with a metallic texture.

[0054] In this step, after obtaining the above-mentioned target inkjet printing substrate, it is also necessary to print the preset target image on the surface of the target inkjet printing substrate, that is, the preset target image is printed in the preset target image shape area on the target inkjet printing substrate. Since there is an adhesive spray layer in the shape of the preset target image on the target inkjet printing substrate, and a metal foil film layer is attached to the adhesive spray layer, when the preset target image is printed in the corresponding area by digital color printing, since the digital color printing method is CMYK (C: cyan; M: magenta; Y: yellow; K: black) color mode to achieve full-color printing, and there is a laminated metal foil film on the target inkjet printing substrate, the CMYK ink cannot completely cover the metal texture of the metal foil film substrate. At this time, through observation, the printed color image partially transmits the metal texture of the metal foil film substrate, so that the entire target color pattern print presents a colorful and eye-catching metallic texture luster.

[0055] In one embodiment, Figure 5 As shown, the above-mentioned digital printing method with metallic texture is used to print the ancient style jar pattern with metallic texture. Figure 6 This is an ancient jar pattern obtained by traditional printing method. Obviously, Figure 5 The shown portion transmits the metallic texture of the metal foil film substrate, making the entire target color pattern print present a colorful and eye-catching metallic texture luster.

[0056] The above-mentioned digital printing method with metallic texture comprises using a preset adhesive spraying agent to perform spraying on a preset substrate surface according to a preset target image shape to obtain a preliminary spraying substrate, performing primary curing on the preliminary spraying substrate to obtain a preliminary spraying substrate after primary curing, laminating the preliminary spraying substrate after primary curing and a preset metal foil film to obtain a laminated spraying substrate, performing secondary curing on the laminated spraying substrate to obtain a secondary cured spraying substrate, removing excess metal foil film from the secondary cured spraying substrate to obtain a target spraying substrate, printing the preset target image on the target spraying substrate according to a digital color printing method, and obtaining a target pattern printed product with metallic texture, and the digital printing method comprises: The color printing method of the digital printing is CMYK (C: cyan; M: magenta; Y: yellow; K: black) color mode to achieve full color printing. Due to the presence of a laminated metal foil on the target inkjet printing substrate, the CMYK ink cannot completely cover the metal texture of the metal foil substrate. At this time, through observation, the printed color image partially transmits the metal texture of the metal foil substrate, making the entire target color pattern print present a colorful and eye-catching metallic luster. The above-mentioned digital printing method with metallic texture does not require complicated processes. It only needs to laminate the metal foil at the position of the image where the metallic texture needs to be expressed, and the position where the metallic texture does not need to be expressed does not need to be processed, which greatly reduces the complexity of the process.
