Knowledge of Tattoo Needles
If you want to do well, you must first use sharp tools. From the explanation of "the relationship between needle and skin", we have a general understanding of the relationship between pigment levels. Then we will talk about "the knowledge of needle". Many people think that needles seem to be no different, but they use the acuteness of needles to destroy the skin and make pigments penetrate into the skin. Although that's true, the needle itself is quite learned to explore.
The sharpness of the needle will affect the presentation of color patches. For the same size of color patches, the smaller the needle points, the less the penetration of pigments at each point, the lighter the texture of the aggregated color patches, which can penetrate the skin or scratch the skin with a very slight force, so the control in the process of puncturing light fog must be very careful. When the Tao is not well used, the depth is easy to vary. Some sections are too deep and too shallow to present a spot-like or oblique situation. On the contrary, blunt needles have larger needle points and more penetration of pigments. The color block texture presented by aggregation will be heavier. The blunt needles must have a certain degree of force to penetrate, and will not easily scratch the skin, but in the case of blunt needles, they will not scratch the skin easily. However, there are concerns about excessive needle points when puncturing fog. If the needle points are not well controlled, the phenomenon of spot uneven will also occur.
We know that the acuteness of the needle has such an effect, we can infer the method of application. On the basis of the theory of "shallow fog", the acuter needle has the advantage of small needle points. As long as we avoid the shortcomings that it is easy to make, we can naturally pierce the beautiful shallow fog, and the slight force can pierce the skin too deeply, so we can find ways to make it difficult to penetrate too deeply. Deep. As for blunt needles, they have the advantage of being difficult to penetrate, so we have to avoid the sense of large amount of needle points. From the acuteness of the needle, we can deduce that the thickness, quantity and arrangement of the needle are different, and the effect of the needle will be different. Next, we will analyze the different types of needles in the existing tattoo techniques.
 Single needle: Usually used in delicate graphics, the advantages are easy to control, sharp enough to enter the needle easily, not too heavy force, so the tattoo machine speed does not need to be adjusted too fast, too sharp too fast easy to damage the skin too heavy, slow adjustment speed control is good, slowly can pierce out very delicate drawings. The disadvantage is that the single needle penetrates into the skin very little, the large color block is not suitable for single needle penetration, the penetration of the pigment will not be thick enough, and the completion time of the work will be longer. If the single needle is used for rapid sectioning, we must pay attention to the appropriate movement of the hand with the tattoo machine, if the depth is too deep or the pause is too long, because the single needle is too fast and easy to cut. When many microvasculatures are broken, the pigments will infiltrate into the microvasculature too much and cause halo.
 Three needles: This kind of needle combines the needle ends of three needles into a single needle end. It is easy to retain more pigments by using the gap between the needle and the needle. It has a good penetration effect when penetrating the skin. It is suitable for penetrating the figure outline.
 Round needle: A cylindrical needle is formed by combining multiple needles, which will retain more pigment in the gap between needles and needles, while multiple needles will form a needle surface. According to five needles, adjusting speed can puncture thicker lines, slowing down speed can also puncture light and dark colors of small details, and more than ten needles can quickly puncture large areas of colors. Block, here is a point that we must pay attention to, when multiple needles form a needle surface, the force area of the whole surface is large, naturally it is not easy to penetrate into the skin, will be pricked in the shallow layer of the skin, in light fog and dark layer color is very good to use, but if intentionally want to prick deep, it will ruin the skin surface and make the color effect not good, so it is not suitable for deep. Pricking of layers of skin.
 single-row needle: multi-needle combination into single-row needle, mostly four to six needles, row needle has the advantage of combining single needle and round needle, easy to penetrate needle, penetration amount of pigment is enough, can be at the least "number of thorns" to puncture more than round needle amount of pigment, but excessive advantage is not suitable for puncturing the whole skin color block.
 Double-row needles: Combining multiple needles into double-row needles, for example, five-needle single-row needles, lifting and fixing two or four needles into two rows, double-row needles with more than five needles, and so on. Double-row needles have the disadvantage of reinforcing single-row needles. Because the needles with dispersed components are more able to puncture the whole area of color block than single-row needles, which is the most popular at present. One thing we must pay attention to when we use needles all over the world is that they usually have the influence of the stress surface when they are over thirteen needles. When they penetrate the skin, the skin will be compressed to form concave shape. If the needles are too wide, they will only be forced on both sides of the needles. They may pierce uneven colors. Therefore, some needles above thirteen needles will stick to circular arcs to fit the skin. The concave shape formed by skin compression, if not adhered to a circular arc, can be as long as the skin is as flat as possible.
 More than three rows of needles: mostly used in large areas of color block, as far as I know, the use of this needle tattoo artists are relatively small, with Japanese tattoo artists as the majority, should be a kind of needle habit of Japanese manual tattoos, the effect can be punctured very dense layer of color, better than the effect of round needles.
 The thickness of the needle and the length at the tip of the needle:
Nowadays, needles commonly used range from 0.25 mm to 0.4 mm in diameter. Except for the difference of single needle in diameter, the gap distance between each needle and multiple needles will be different. Detailed rules are more dense than coarse ones, and the effect of puncturing will be different. It is not easy for dense ones to penetrate shallowly, and vice versa. The length at the tip of the needle is the same as the thickness.
