Black ink is a liquid containing melanin or dye. Black ink is used for writing or painting. The earliest black inks were dyes made from metal materials, walnut shells or seeds, or inks made from aquatic creatures such as fish and squid. The ink in our country is carbon ink. Black ink is divided into dye ink, pigment ink and thermal transfer ink. Most people don't know exactly what kind of black ink to use.
What is black ink made of?
The main raw material of black ink is melanin or dye. Generally, in order to prevent it from being wiped off, some other substances are added. Liquids made from dyes easily penetrate into the paper, making it difficult to print. Different colors of black ink have different dyes and pigments, and their application areas are also different.
Black ink is a liquid containing melanin or dye. It is mostly used for writing or art painting. The signature pens or soft pens we often use are dipped in black ink for writing. Most of the black ink in our country is carbon ink. In order to prevent the melanin or dye inside from being wiped off, some other substances will be added.
Black ink produced with dye is a liquid produced by melting fuel in water. This type of ink will not clog the pen when used, but one drawback is that it can easily penetrate into the paper. Inside, if it is used for packaging and printing, there will be certain technical obstacles, and it is necessary to find ways to speed up the drying of black ink.
Black ink generally has three colors: red, black and blue-black. The dyes and melanin are different and the colors are different. Red ink can be used for batch assignments, and blue-black ink is initially used. It turns blue when you write, and turns black after you write, so you can write smoothly. Black ink is more common and is best used for pen writing or calligraphy.
The difference between dye ink and pigment ink
Dye ink is a fully melted black ink at the molecular level. This type of black ink is a complete compound aqueous solution and has a low chance of clogging the ink head. Large, easy to be digested and absorbed by raw materials after spray painting, bright colors, and low construction cost.
The disadvantage is not moisture resistance, and because the molecular structure of the dye dissolves quickly under ultraviolet irradiation, it will cause problems when used outdoors under ultraviolet light. There will be significant fading within a month. The advantage is that the colors are bright, the texture is clear, and the price is lower than color paste-type black ink. Therefore, it is the first choice product for printing pictures, making color inkjet business cards and other important purposes.
Pigment ink is, to put it more vividly, powdered black ink. Of course, this is just a figurative name and not accurate enough. To be more precise, it grinds the solid color paste into very fine particles and dissolves it in a unique water organic solvent. It is a floating aqueous solution or a semi-aqueous solution, which has the same characteristics as the color paste for clothes in our printing and dyeing factories. Completely opposite to the basic principle of dye ink penetrating into the material to produce color, it produces color based on the color material attached to the surface of the material (such as color copy paper or copy paper, etc.).
Therefore, the advantage is that when copying with pigment ink, the ink will not smear even when copying on ordinary paper, and because the color paste itself is moisture-proof, it is not easily dissolved by ultraviolet light, so it has excellent wear resistance. It is strong and light-resistant. Even if the printed items are used outdoors, they can last for more than a year without obvious signs of fading.
