Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one such feature.

If a combination of technical solutions contradicts or cannot be implemented, such combination of technical solutions shall be deemed non-existent and not within the scope of protection claimed in this application.

[0069] like Figure 1 As shown, a 3D printing method for a refractive index-changing image, the refractive index-changing image includes a first target display image within a first refractive index viewing angle range and a second target display image within a second refractive index viewing angle range, and the 3D printing method includes:

[0070] Step S110, configure and generate a printing data control model for the refractive index-changing image according to the first preset refractive index viewing angle range, the first target display image, the second preset refractive index viewing angle range, and the second target display image.

[0071] The refractive index-changing image displays different images within different refractive index viewing angle ranges, displays the first target display image within the first preset refractive index viewing angle range, and displays the second target display image within the second preset refractive index viewing angle range.

[0072] In this embodiment, the first preset refractive index viewing angle range and the second preset refractive index viewing angle range do not overlap, the first refractive index viewing angle range is 45 to 120 degrees, and the second refractive index viewing angle range is 130 to 170 degrees.

[0073] In one embodiment, both the first target display image and the second target display image are character images, such as Chinese character images.

[0074] In one embodiment, the Chinese character image is "Ju", and the first target display image within different refractive index viewing angle ranges is as Figure 2 shown.

[0075] In one embodiment, both the second target display image and the first target display image are Chinese character images. For example, take the first target display image "Ju" and the second target display image "Jin".

[0076] It should be noted that both the first target display image and the second target display image are target display images of the same format and size.

[0077] In this example, both the characters "Ju" and "Jin" are Chinese character images of the same font and the same size, for the convenience of comparing the two, as Figure 3 shown.

[0078] In this embodiment, after obtaining the first preset refractive index viewing angle range, the first target display image, the second preset refractive index viewing angle range, and the second target display image, a printing data control model for generating a refractive index-changing image can be further configured.

[0079] Step S120, when the printing data control model is obtained, generate a substrate positioning instruction.

[0080] After the digital control processor obtains the printing data control model, it can further generate a substrate positioning instruction.

[0081] Step S130 : acquiring positioning data of the target printing substrate according to the printing substrate positioning instruction.

[0082] During the printing process, the target substrate needs to be kept in a suitable and correct position. The substrate positioning instruction includes the positioning data of the target substrate. Therefore, the positioning data of the target substrate can be obtained according to the substrate positioning instruction.

[0083] Step S140 : determining whether the target printing object is located within a preset position range based on the positioning data.

[0084] The target printing substrate usually needs to be placed within a certain preset position range. After obtaining the positioning data, it can be further determined whether the target printing substrate is located within the preset position range.

[0085] Step S150 : When it is determined that the target printing material is located within the preset position range, a printing instruction is generated according to the printing data control model.

[0086] In step S160 , a preset spraying material is sprayed onto a target substrate according to the printing instruction to obtain a preliminary printed product including a spray layer.

[0087] In one embodiment, the preset spraying material is ink.

[0088] Step S170 , performing preliminary pre-curing treatment on the sprayed layer to control the leveling property of the sprayed material, and obtaining a pre-cured printed product.

[0089] Among them, the initial pre-curing treatment usually uses LED ultraviolet lamps for irradiation to control the leveling of the spraying material and obtain pre-cured printed products.

[0090] In one embodiment, the control accuracy of the leveling is 450 DPI.

[0091] Step S180 , performing a full curing process on the pre-cured printed product to obtain a printed product containing a refractometric image.

[0092] In this embodiment, the full curing treatment is usually performed using a UV mercury lamp.

[0093] Compared with the traditional method of using complex processes such as molds, molding, positioning, and die-cutting, and using output files as the production basis and inkjet to produce finished products, the above-mentioned 3D printing method of refractive index-changing images can directly output refractive index-changing images on various special materials such as paper, film, and leather through inkjet printing. The process is simple, which can reduce the complexity of the process, realize batch 3D printing of refractive index-changing images, and reduce economic costs.

[0094] In one embodiment, as Figure 4 shown, step S110 includes:

[0095] Step S112, determining a first to-be-printed line layer model and corresponding first printing parameter information according to a first refractive viewing angle range and a first target display image, where the first printing parameter information includes the shape, length, thickness, arrangement, line layer spacing, and matching angle of each line layer of the first to-be-printed line layer model.

[0096] In one embodiment, the first target display image is a Chinese character image. To display the first target display image within the first refractive viewing angle range, it is necessary to configure the shape, length, thickness, arrangement, line layer spacing, and matching angle of each line layer of the first to-be-printed line layer model.

[0097] Among them, the shape of the first to-be-printed line layer model is related to the Chinese character image itself, the length of the first to-be-printed line layer model is related to the size of the first target display image itself, the thickness and line layer spacing of the first to-be-printed line layer model are related to the first refractive viewing angle range, and the arrangement and matching angle of each line layer of the first to-be-printed line layer model are comprehensively affected by the first refractive viewing angle range and the first target display image.

[0098] Step S114, based on the first to-be-printed line layer model and the first printing parameter information, calculating and matching a corresponding second to-be-printed line layer model and corresponding second printing parameter information in combination with a second refractive viewing angle range and a second target display image, where the second printing parameter information includes the shape, length, thickness, arrangement, line layer spacing, and matching angle of each line layer of the second to-be-printed line layer model.

[0099] Step S116, establishing a printing data control model for a refractive changeable image according to the first to-be-printed line layer model and corresponding first printing parameter information, and the second to-be-printed line layer model and corresponding second printing parameter information.

[0100] In one embodiment, as Figure 5 shown, step S114 includes:

[0101] Step S114a, comparing the second target display image with the first target display image to determine the overlapping area and non-overlapping area between the two.

[0102] In one embodiment, both the second target display image and the first target display image are Chinese character images. For example, taking the first target display image "Ju" and the second target display image "Jin" as an example, the two characters can be compared to determine the overlapping area and non-overlapping area between the two.

[0103] It should be noted that both the first target display image and the second target display image are target display images of the same format and size.

[0104] In this example, the Chinese characters "Ju" and "Jin" are both Chinese character images of the same font and the same size, which is convenient for comparing the two.

[0105] In this embodiment, when the images are both Chinese character images, when determining the overlapping area and non-overlapping area between the two, in some areas, the stroke trends need to be combined to make the strokes of the two coincide as much as possible.

[0106] For example, for the Chinese characters "Ju" and "Jin", the vertical stroke of the radical "Zouzhi" of the character "Jin" is simplified to a vertical stroke to coincide as much as possible with the vertical stroke part of the single-person radical of the character "Ju", and the horizontal stroke part of the character "Jing" of the character "Jin" coincides as much as possible with the internal horizontal stroke part on the upper side of the part of the character "Ju" of the character "Ju".

[0107] Step S114b: According to the second refraction viewing angle range, based on the first to-be-printed line layer model in the overlapping area, determine the second to-be-printed line layer model corresponding to the second target display image in the overlapping area and the corresponding line layer parameter information.

[0108] In this embodiment, in the overlapping area, based on the first to-be-printed line layer model, it is necessary to further adjust the first to-be-printed line layer model and the corresponding line layer parameter information according to the second refraction viewing angle range to determine the second to-be-printed line layer model corresponding to the second target display image in the overlapping area and the corresponding line layer parameter information.

[0109] Step S114c: According to the second refraction viewing angle range and the second target display image, based on the second to-be-printed line layer model corresponding to the second target display image in the overlapping area and the corresponding line layer parameter information, determine the second to-be-printed line layer model and the corresponding line layer parameter information in the non-overlapping area.

[0110] In this embodiment, based on the fact that the second to-be-printed line layer model corresponding to the second target display image in the overlapping region needs to be connected and combined with the second to-be-printed line layer model in the non-overlapping region to display the second target display image, it is necessary to consider the line layer matching angle between the two, the second refractive viewing angle range, and the second target display image itself. The second refractive viewing angle range and the second target display image determine the shape, length, thickness, arrangement, line layer spacing, and each line layer matching angle of the line layer model in the second to-be-printed line layer model in the non-overlapping region. Step S114d: Determine the second to-be-printed line layer model and the corresponding second printing parameter information according to the second to-be-printed line layer model and the corresponding line layer parameter information in the overlapping region, and the second to-be-printed line layer model and the corresponding line layer parameter information in the non-overlapping region. The second printing parameter information includes the shape, length, thickness, arrangement, line layer spacing, and each line layer matching angle of the second to-be-printed line layer model.

[0111] In one embodiment, as Figure 6 shown, step S114b includes:

[0112] Step S114b1: Determine the line layer parameter information of the overlapping line layer between the second to-be-printed line layer model and the first to-be-printed line layer model in the overlapping region according to the second refractive viewing angle range.

[0113] In one embodiment, for example, taking the characters "ju" and "jin" as an example, as Figure 7 shown, Figure 7 in the overlapping region between the second to-be-printed line layer model and the first to-be-printed line layer model, the parameters of the overlapping line layer are slightly adjusted relative to the first line layer parameter information corresponding to the first to-be-printed line layer model. According to the second refractive viewing angle range, in the T1 region (taking one of the regions T1 for illustration) in the overlapping region in the figure, it is necessary to modify the first to-be-printed line layer model, for example, make appropriate changes to the thickness and line layer spacing. In Figure 7 the T2 region in the overlapping region, the first to-be-printed line layer model and the corresponding line layer parameter information are kept unchanged.

[0114] Among them, Figure 7 in the overlapping region of

[0115] Step S114b2: Determine the region where the non-overlapping line layer between the second to-be-printed line layer model and the first to-be-printed line layer model is located in the overlapping region.

[0116] In one embodiment, for example, taking the characters "Ju" and "Jin" as examples, the area of the non - overlapping line layers between the second to - be - printed line layer model and the first to - be - printed line layer model in the overlapping area is exemplified as Figure 7 shown in the T3 area in Figure 7 (illustrated by one of the areas). At this time, based on the first to - be - printed line layer model in the area of the non - overlapping line layer, according to the second refractive - angle view range, the corresponding line - layer parameter information is adjusted and used as the second to - be - printed line layer model in the area of the non - overlapping line layer to satisfy the display of the corresponding partial structure of the character "Jin" within the second refractive - angle view range. For the overlapping line layers and non - overlapping line layers at other positions in the characters "Ju" and "Jin", they are set similarly to ensure the display of the first target display image within the first refractive - angle view range and the second target display image within the second refractive - angle view range.

[0117] In one embodiment, the printed product containing the refractive - changeable image printed by the above 3D printing method is as Figure 8 shown and Figure 9 shown, where the first target display image, the character "Ju", is displayed within the first view range, and the second target display image, the character "Jin", is displayed within the second view range.

[0118] In one embodiment, the above 3D printing method further includes:

[0119] When it is determined that the target substrate is not within the preset position range, a paper - transportation instruction is generated and sent to the paper - conveying platform, so that the paper - conveying platform transports the target substrate to within the preset position range.

[0120] In addition, as Figure 10 shown, there is also provided a printing device 200 for refractive - changeable images.
