Example Embodiment
[0036] Example 1
[0037] A method for preparing three-dimensional surface glaze includes the following steps:
[0038] 1. Select at least one single color in the image to prepare a screen plate;
[0039] 2. On the semi-finished blank, glaze with a pattern printed on the screen, and the glaze is powder;
[0040] 3. Fired into the kiln to obtain ceramics with three-dimensional glaze.
[0041] After printing, the highest stacking height of the glaze is 0.4~5mm, keeping the gaps in the pattern.
[0042] The semi-finished blank is sintered and dried.
[0043] The surface of the blank is colored with a screen.
[0044] A primer is applied to the surface of the blank.
[0045] In the third step, an 80-mesh screen is used in the screen printing of the surface glaze.

[0046] Example 2
[0047] A preparation method of three-dimensional surface glaze includes the following steps:
[0048] 1. Select at least one single color in the image to prepare a screen plate;
[0049] 2. On the semi-finished blank, glaze with a pattern printed on the screen, and the glaze is powder;
[0050] 3. Fired into the kiln to obtain ceramics with three-dimensional glaze.
[0051] After printing, the highest stacking height of the glaze is 0.5~3mm, keeping the gaps in the pattern.
[0052] The semi-finished blank is sintered and dried.
[0053] The surface of the blank is colored by roller and / or gravure.
[0054] A primer is applied to the surface of the blank.
[0055] In the third step, an 80-mesh screen is used in the screen printing of the surface glaze.
Example Embodiment
[0056] Example 3
[0057] A preparation method of three-dimensional surface glaze includes the following steps:
[0058] 1. Image processing;
[0059] Select at least one single-color color development in the image to prepare a screen screen; the color development refers to visually prominent color blocks, color blocks with a larger area, and color blocks that require bright colors.
[0060] Visually prominent color blocks can be screen-printed to ensure that vivid colors with accurate hue, high color saturation and high gloss are obtained. The screen printing method can also have the effect of three-dimensional relief.
[0061] Color blocks of bright colors are needed. In the gold formed by inkjet printing, the finished product is displayed as brown, and the effect is not good. The screen printing method, especially the use of metal-containing powder to print gold, has a very Bright effect, high reflectivity, saturated color, and can have the effect of three-dimensional relief, perfe...
