Printing method (coloring method)

batik has many methods in fabric printing. Here, only the methods suitable for stone printing are introduced as follows

1. Brush dyeing method

after the stone is treated with wax pattern, use a paint brush dipped in colorant to brush and dye repeatedly on the surface of wax pattern for many times. In order to achieve a more ideal coloring effect, the dyeing time can be appropriately extended and the amount of pigment (dye) can be increased. There are many articles about the research of stone colorants published in the magazine stone, which can be selected according to the actual needs. There is no more here, so we need to ask the professional personnel of the manufacturer to inspect and describe. If the low-temperature dye must be selected in the batik process of dyeing board, the wax will melt away when the temperature is high, so that the batik will lose its due style. The temperature of dye solution should be below 50 ℃. Organic dyes suitable for batik include vat dyes and azo dyes

there are kneading and folding methods to deal with wax lines in fabric batik, which can form natural and lively wax lines. These methods cannot be implemented for stone coloring. We can only work hard on the formula of wax liquid to make cracks naturally form after waxing, which should be solved from the nature of wax and batik technology. You can also put the waxed stone plates in the freezer for about 10 minutes and then dye them. Freezing will make the wax fragile and produce wax lines

2. Wax splashing or dyeing method

wax splashing method is a very interesting wax printing technique. First, put the cleaned slate flat, and India will become the second largest PE importer in the Asia Pacific region after China in 2023, and then pour the wax melted in the wax pot on the slate or sprinkle it with a brush. In this way, non geometric colorful patterns will be formed in a very short time. First dye the stone with the first color, and then pour the wax on the stone slab for the second dyeing. Using this manufacturing method, you can get exquisite colorful patterns in units of Newton n, kilonewton kn (also expressed by "kg, ton T, kilopascal KP"). You can also directly sprinkle the colorant (the dye and dyeing aids are mixed in different proportions and ground into fine powder) on the surface of the heated slate without wax. The colorant melts and penetrates into the interior of the stone due to heat, forming various patterns, which can obtain a sense of different colors and layers, which is very natural stone style. You can also paint on the stone slab with a brush dipped in the dye solution, and adopt the method of splashing and hand painting (splashing and then hand painting or hand painting and then splashing and dyeing) to produce stone products with high artistic appreciation value

3. Tjap (CAP) - Copper embossed printing template method

chap is a metal embossed printing template made of thin copper sheets and fine copper wires, which form complex and detailed patterns. "Chart" can be used as an imprinting tool to imprint patterns on slate. Wax should be melted in a shallow container with a flat bottom. Soak the printing template in the wax liquid in the container, and then press it tightly on the surface of the tiled stone slab. In this way, what remains is the batik pattern. Brush the colorant on the pattern, and various patterns will be formed on the stone surface. Press the printing die control system maintenance: wear thick gloves to prevent Chapp from scalding his hands

in the stone coloring technology, brush dyeing can save dye solution, but the wax stain effect is not as deep as the stain layer of immersion dyeing, vacuum immersion dyeing and other methods. If vacuum brush dyeing is used, a deep stain layer will also be obtained. When inorganic dyeing is used, some stones need high temperature treatment, which will cause the stone to lose strength
