Ink is a colloid containing pigments or dyes. Ink is used for writing or painting. The earliest inks were dyes made of metal, walnut shells or seeds, or inks made of marine animals such as fish and octopus. China ink is carbon ink.
Ink is divided into dye ink, pigment ink and thermal transfer ink.
Huizhou ink
Hui ink is made of pine as the basic raw material, with more than 20 other raw materials, through the processes of cigarette lighting, blending, pressure grinding, air drying, trimming, gold painting, boxing and so on. The finished product has the characteristics of deep color, solid luster, no smudge when entering the paper, no glue when licking the pen, no fading for a long time, rich fragrance, corrosion resistance and moth prevention. Suitable for painting and calligraphy, known as "fragrant bones, slag leaves no inkstone." The color of Hui ink can be divided into five levels: burnt, heavy, thick, light and clear. The ink color lasts for thousands of years, and the ink color is black and moist. Used in calligraphy and painting, the varieties are endless and interesting. Both sides are also engraved with various patterns, which are beautiful and generous, and are treasures of painting and calligraphy.
In ancient China, "Hui ink" was always the best ink. Hui ink, as its name implies, is the ink produced in ancient Huizhou. Huimo, of course, refers to the "ancient Huizhou" which consists of Shexian, yi county, Qimen, Xiuning, Jixi and Wuyuan.
Pigment manufacturing
Ink made of pigment is generally mixed with other substances to prevent the pigment from being wiped off. Such ink generally does not penetrate into paper, so the ink used in printing can reduce the printing cost.
Common colors
Common colors of ink are red and black, such as ink and blue and black. Red ink is generally used to correct homework, and the scope of use is relatively small. Blue-black ink is ultra-white, easy to fade and smooth to write, which is commonly used in people's study and work. Carbon ink is the most ideal black ink. Black ink has no density and luster. Writing on paper stands out. Used to write pen words or pen calligraphy works, the effect is very good.
Dye manufacturing
Ink made of dyes is stronger, but it is usually soluble in water. They penetrate into the paper, and may also penetrate into the back of the paper, so there are certain technical obstacles in printing. Therefore, this kind of ink generally uses a solution that dries very quickly or tries to accelerate the drying of the ink when printing. Other techniques include using harder paper or using special paper.
Matters needing attention
Ink should be the same brand and color, and cannot be mixed, otherwise it will precipitate, which is not conducive to writing. Wear a pen cap in time after each writing, otherwise the ink on the pen tip will dry, and the water will not be smooth when writing again. If you want to use another ink, you should wash your pen and dry it before loading new ink.
