Length of the stroke （Tattoo Needles）
Generally, the length of the stroke is about 1.5mm when outlining. However, it should be 2-3mm when shading. Since tattoo tips are against the skin, according to the principle of physics, the smaller the area, the bigger the pressure, so it is easy for tattoo needles to pierce the skin, and the whole needles can pierce the skin.
How to avoid scars?
Many people will have scars after getting a tattoo, which is called epidermal hyperplasia. It is annoyed. Many reasons can cause scars, such as tattoo needles pierce skin too heavily or too powerfully, which hurts the skin and then a scar will appear. The tattoo ink that contains allergic ingredients or toxic substance will also cause scars. If you don’t take care of the wound properly, there will be a chance to have a scar. What is more, it is more easy for the people whose skin is keloid-prone skin to have a scar. Except for personal physique, tattoo ink materials, and improper maintenance, the methods and the power of tattooing are the key factors. Generally speaking, the needles had better reach the dermis when tattooing, so that tattoo ink particles can be deposited in the skin better without being absorbed by the body, as a result, the color will look the best. If the needles only reach the epidermis, the color will disappear when epidermis fall off. But the structure of the skin may be damaged as the needles reach the dermis, which may cause skin hyperplasia and scarring. If the needles reach deeper, the damage to the skin is more and the scar is more likely to occur. The epidermis layer skin is generally between 0.06 and 0.1 mm. The dermis lies beneath the epidermis. Everyone will know how deep the needle should penetrate according to the data. Besides, the skin may be smashed if tattoo needles reach the skin iterative or vigorously, which may cause skin damage to be serious and form scars. Therefore, in terms of the method of the tattoo, the technique and strength are the keys.
The relationship between tattoo needles and skin
Good tools are prerequisite to the successful execution of a job. Many people think that there is no difference in tattoo needles，just use the sharpness of the needle to pierce the skin let the tattoo ink penetrate the skin. Although it’s true the "needle" itself has a lot of knowledge needs to study. The sharpness of the needle affects the presentation of the colors. In the case of the same tattoo inks, the sharper needles and smaller needle points will infiltrate fewer inks, and the color will show lighter. With a slight force, it can penetrate the skin or scratch the skin, so the control in the process of light shading must be very careful. When the strength is not working well, the depth will be different, various shades will show spotted. On the contrary, the blunt needle has a larger needlepoint and more inks penetration, and the color of the tattoo pattern will be heavier. The blunt needle must have a certain degree of force to penetrate, and will not easily scratch the skin. However there is a big concern about the oversized needlepoint when you are shading, and if the control is not good, there will be a phenomenon of uneven spots. We know that the sharpness of the needle has this effect, and we can speculate on the method used. As” light shading”, a sharper needle has the advantage of a small needlepoint, as long as we avoid the shortcomings that it is easy to make, we can naturally tattoo the beautiful shade. A slight force can penetrate the skin deeply, so we can find a way to make it difficult to penetrate too deeply. In the case of a blunt needle, there is an advantage that it is not easy to penetrate, and we have to avoid the disadvantages of a large needlepoint. In this way, starting associate from the sharpness of the needle, it can be inferred that the thickness, number, and arrangement of the needle are different, and the effect of the tattoo will be different. Next, we will analyze the effects of different types of needles in the existing tattoo technique.
1.1RL ：Usually used for exquisite tattoo pattern, the advantage is easy to control. The sharpness easily pierces the skin and does not require heavy effort. Therefore, the speed of the tattoo machine does not need to be adjusted too fast, too sharp and too fast will damage the skin too Slow speed can be better controlled, you can slowly tattoo a very exquisite pattern. The disadvantage is that there is very little tattoo ink that penetrates the skin. The large color pattern is not suitable for a tattoo with 1RL tattoo needles, the penetration of the inks will not be thick enough, and the work will take a long time to complete. When you use 1RL tattoo needles to lining in a fast speed, you must pay attention to the cooperate with the movement of the hand and the tattoo machine. Because the 1RL tattoo needles are too fast, it is easy to cut many microvessels, if the depth is too deep or the pause is too long, it will infiltrate into the microvessels and cause the blooming phenomenon.
4、Magnum（M1）：The magnum tattoo needles combine multiple needles into a double row of needles. Like 5M1 tattoo needles, it fixes the second and forth needles in two rows. The magnum tattoo needles with more than five needles, and so forth. The magnum tattoo needles have the disadvantage of reinforcing Flat tattoo needles. Because the needles are opened into discrete needle points, compared with the flat tattoo needles, the magnum tattoo needles will shade more.This is the most commonly used tattoo needle type. But you must be noticed, it will be affected by the force surface above 13 needles. When it is pierced to the skin, the skin will be pressed to form a concave shape. A magnum needle that is too wide will only be used on both sides of the needle, which may tattoo uneven colors. Therefore, some of the 13 or more needles will be glued into a circular arc shape to fit the concave shape formed by the compression of the skin. If it is not glued in a circular arc shape, you can flatten the skin as much as possible.
5. Triple Magnum or more: Generally it used for a large-area color pattern. As far as I know, fewer tattoo artists are using this kind of needle and most are Japanese tattooists. The effect can tattoo a very dense color layer, which has a better effect than a round needle.
6. The thickness of the needle and the length at the tip of the needle：
