Through digital image processing technology and UV printing technology, a planar picture is transformed into a three-dimensional structure diagram with complex height changes, realizing the rapid and low-cost production of high-quality three-dimensional decorative murals on the coil.

[0038] Please refer to Figure 2 , a preparation method for a super-relief mural with intelligent height gradient, comprising the following steps:

[0039] S1: Image acquisition. Place the planar pattern on the scanning table. The planar pattern is a hand-drawn pattern and a printed pattern. Level and expand the surface of the planar pattern and scrape it horizontally multiple times to keep the planar pattern completely attached to the surface of the scanning table. Use a high-resolution scanner to perform an omnidirectional scanning operation on the planar pattern and obtain the electronic image of the planar pattern;

[0040] S2: Image redrawing. Upload the obtained electronic image to the computer and redraw the electronic image through the graphic software of the computer, especially paying attention to defining the height parameters of different regions to ensure precise control from the most prominent part to the smoothest transition;

[0041] S3: Data processing. Preset the parameters of the UV printer, specifically measure the usage amounts and relative ratios of white ink and other color inks by a specific algorithm, and then inject white ink and other color inks into the ink cartridges of the UV printer according to the measured usage amounts;

[0042] S4: UV printing. Transmit the redrawn electronic image data into the UV printer, place the coil of the relief mural of the corresponding size in the printing area to be printed of the UV printer, spray the surface of the coil with a coating using a spray gun, start the UV printer, and the UV printer performs multi-layer ink stacking printing on the coil according to the preset parameters;

[0043] S5: Image forming process. After printing, clean the surface of the formed image with a brush dipped in alcohol, and then place it in a curing box for static placement. The ultraviolet light source of the curing box is used to irradiate the image surface sufficiently.

[0044] The specific algorithms include the height and white ink distribution algorithm and the color ink distribution algorithm. The height and white ink distribution algorithm is as follows:

[0045]

[0046] Where W(x, y) is the white ink deposition amount of the pixel at (x, y), H(x, y) is the designed height of the pixel at (x, y), and k is the height increment constant corresponding to unit white ink;

[0047] The height and white ink distribution algorithm is used to calculate the required white ink deposition amount W(x, y) according to the designed height H(x, y);

[0048] The color ink distribution algorithm is as follows:

[0049] CMYK(x, y) = f(C(x, y), W(x, y));

[0050] Where CMYK(x, y) is the CMYK ink deposition amount of the pixel at (x, y), C(x, y) is the designed color of the pixel at (x, y), and f is the color mapping function;

[0051] The color ink distribution algorithm is used to calculate the required ink deposition amount CMYK(x, y) according to the designed color C(x, y) and the white ink deposition amount W(x, y);

[0052] Through the height and white ink distribution algorithm and the color ink distribution algorithm, the height and color parameters of each pixel forming the relief mural can be accurately measured.

[0053] Among them, UV printing consists of height mapping, color mapping, and printing control. Height mapping is to determine the height of each pixel of the relief mural through the height and white ink distribution algorithm. Color mapping is to convert the designed color C(x, y) into the ink deposition amount CMYK(x, y) by using f, lookup, and table, and considering the influence of the white ink base. Printing control is to first print the white ink W(x, y) to construct the height structure, and then print the color ink deposition amount CMYK(xy) on the basis of the white ink to achieve the designed color;

[0054] The designed height H(x, y) does not exceed the maximum printing height of the UV printer. Both W(x, y) and CMYK(x, y) are processed by a smoothing filter to avoid obvious delamination or banding between layers, and can effectively control the height and color of the super relief mural.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in all respects, the embodiments should be considered exemplary and non-limiting, and the scope of the present invention is defined by the appended claims rather than the above description.
