[0043] In the present application, according to specific embodiments, comprising an electronic document processing step before copying, a printing step and a manufacturing step,

[0044] The electronic document processing step before copying comprises the following steps:

[0045] ①, the original oil painting is scanned by HD Ultra i4210s for high-definition texture picture, with a scanning resolution of 1200x1200dpi and a scanning color of 1:1 reduction, and color matching is performed by Epson Artisan MicroEdge printer; convert the file to printing mode cmyk, browse the picture texture height and highlight area, the highlight color will have light white, intermediate value (gray), dark black, find out the picture highlights, pay special attention to whether the texture at these positions is completely presented when making the texture file;

[0046] 2. Turn to cmyk channel window, find out where the highlight skin texture in the channel display particularly clear, the channel color (such as light color) with clear texture drag to the "create new channel" button release the left mouse button to copy channel, and click the upper right corner of the small triangle function bar to select "channel options", open the settings dialog box to select "color indication - spot color", the name is changed to the first skin color layer, the current picture is black and white, select the menu "image - adjustment - inverse", you will find that the original light color, that is, the skin texture is higher, the convex skin texture from the original light white color into dark gray or black, the output of the dark part will be the most ink and thickest place, this operation locks the highlight skin texture in the print file;

[0047] 3. The intermediate value in the cmyk four color channels can not find the best skin texture color display channel, then save another copy of the original file, and open it in the picture processing software, "image - mode - grayscale" into grayscale, click the channel window, drag the "gray" channel to the "create new channel" button release the left mouse button to copy the channel, and click the upper right corner of the small triangle function bar to select "channel options", open the settings dialog box to select "color indication - spot color", the name is changed to the second skin color layer, now you can see the picture is light gray and dark gray (60%-75% gray) color, select the menu "image - adjustment - inverse", you will find that the color is opposite to the original, the convex skin texture from the original light gray color into dark gray, the output of the dark part will be the most ink and thickest place, this operation locks the intermediate gray skin texture in the print file;

[0048] 4. Dark gray (80% or more), black skin texture file: select the "black channel" in the channel window, drag the "black" channel to the "create new channel" button release the left mouse button to copy the channel, and click the upper right corner of the small triangle function bar to select "channel options", open the settings dialog box to select "color indication - spot color", the name is changed to the third skin color layer, at this time the dark color, black part does not need to be inverse color, because the inverse color becomes white, the skin texture can not be displayed, and the skin texture effect can not be printed out;

[0049] ⑤, the texture or brushstroke production of the ground color: go to the cmyk channel window, find the channel that shows the texture particularly clearly, drag this color channel to the "create new channel" button with the move tool, release the left mouse button to copy the channel, and click the small triangle in the upper right corner of the function bar to select "channel options" to open the settings dialog box. Select "color indication - spot color" and change the name to the fourth texture color layer. Click the menu "image - adjustment - color level" and drag the black triangle in the "input color level" to the right. Set the left box to 46. Then drag the middle value gray triangle to the right until the middle box is set to 0.35. Finally, drag the highlight triangle to the left and set the right box to 194. At this time, you will find that the ground texture is particularly obvious. Select the menu "image - adjustment - inverse", at this time you will find that some channels in the above will overlap. Use the "eraser tool" with "opacity" set to 80% and "hardness" set to 20% to adjust the size of the eraser according to the needs of the figure. Erase the texture position that is not needed to complete the production;

[0050] ⑥, the highest texture production in the picture: select the highest color channel of the first, second and third texture color layer, drag it to the "create new channel" button with the move tool, release the left mouse button to copy the channel, and click the small triangle in the upper right corner of the function bar to select "channel options" to open the settings dialog box. Select "color indication - spot color" and change the name to the fifth texture color layer. Click the menu "image - adjustment - color level" and drag the black triangle in the "input color level" to the right. Set the left box to 41. Then drag the middle value gray triangle to the right until the middle box is set to 1. Finally, drag the highlight triangle to the left and set the right box to 111. This adjustment only shows the highest part of the texture as dark gray and the rest as white. This parameter may vary slightly on different colors;

[0051] ⑦, the water part of the landscape oil painting often shows dark color when inverted, and the ink accumulation is particularly thick when output. The original work has no or slightly convex texture, which means that this part does not need to be printed too thick. To do this, select the area with the magnetic or lasso tool, and adjust the feathering to 10 to make the transition to the surrounding color more natural. Use the sponge tool, set "mode" to "reduce saturation", and set the flow to "60%" in the selected area. Wipe back and forth to absorb the color to light gray.

[0052] ⑧, if the channels are not ideal for texture adjustment, convert the file to grayscale and repeat the processing operation in ② above.

[0053] ⑨, check the color and texture of each white ink channel to ensure that they are displayed accurately, then store them as five files in order;

[0054] The printing steps include the following steps:

[0055] ①, the used printing equipment selects high-precision high-fall nozzle, the model uses KJ4A-AA print head, the minimum liquid drop amount is 3pL, the resolution is high 600x600dpi, and it is suitable for fine printing;

[0056] ②, the printing color is combined with CMYK+LCLM+W+V, and the ink uses UV [ultraviolet curing] ink. The ink refers to that under ultraviolet irradiation, a UV ink photopolymerization initiator absorbs certain wavelength photons, is excited to an excited state, forms free radicals or ions, then through intermolecular energy transfer, the polymerized prepolymer and the light-sensitive monomer and polymer become excited state, and the charge transfer complex is generated. These complex particles continuously crosslink and polymerize, and are cured into a film. The same position can be printed and stacked with ink to achieve the effect of convex and concave relief, so as to form the texture.

[0057] ③, the texture is printed first when outputting, that is, white ink is printed, and the output is set to be white ink only. Among them, the first texture color layer selects 8 times ink output, the second texture color layer selects 4 times ink output, the third texture color layer selects 8 times ink output, the fourth texture color layer selects 8 times ink output, and the fifth texture color layer selects 16 times ink output. Then, the texture height and the original work are checked. If the texture height does not reach the original work, the fourth texture color layer can be outputted with 8-16 times ink.

[0058] ④, when the texture height is consistent with the original work, the corresponding color is printed according to the surface color value of the oil painting original work, and the printing is completed.

[0059] The manufacturing steps include the following steps:

[0060] ①, the finished semi-finished product is placed in a ventilated place for 8 hours, so that the residual odor is completely dissipated;

[0061] ②, the semi-finished product is coated with damar varnish, and after ventilation and drying, it is framed to complete the production of the oil painting copy.

[0062] Of course, the present application is not limited to the above-mentioned embodiments, and those skilled in the art can make equivalent modifications or replacements without departing from the spirit of the present application. These equivalent modifications and replacements are all included in the scope defined by the claims of the present application.
