Tricks in the process of tattooing

The principle of skin coloring:
the tip of the needle is squeezed into the skin to form a wound, so that the cells around the wound are stained with color, and the dots are arranged into lines and faces to form different patterns. As a carrier, we must understand the skin, the machine and the needle. In order to better complete each work.

First, the skin structure

1. Epidermis: The thickness is about 0.2 mm. The cells are formed at the bottom layer of the epidermis layer and gradually move upwards. The renewal period is 28 days, and the age is about 35 days. The color will be renewed in this layer.

2. Dermis layer: high toughness, resistance to needle formation, thickness of about 0.5-4 mm, skin thickness and toughness of the whole body are different at different positions. The thinnest point is about 0.5 mm in the upper eyelid, and the thickest is about 4 mm in the sole of the foot. The thickness and toughness of the skin vary from person to person. The tattoo is inserted in the needle about 1-2 mm, and the color remains in the dermis and dermis and the subcutaneous tissue. The best.

3. Subcutaneous tissue: relatively soft to the needle resistance, distribution of nerves, blood vessels and so on. When the needle penetrates the dermis. Injury to the subcutaneous tissue, it is easy to cause skin damage such as blooming, skin damage, hyperplasia, discoloration.

Second, the machine

Coil machine: The working principle is that after the electromagnetic coil is energized, the suction force is generated, and after the power is turned off, the frequency is rebounded 50 times per second vertically. The strength and frequency of each machine are different, and the voltage directly affects the machine. Strength, frequency change is not obvious.

Motor machine: frequency is stable, frequency is about 60, mute, voltage can control the frequency and strength of the machine, easy to operate, pressure and movement speed and number of passes can control needle depth and pin point density, the biggest advantage is effective penetration The color is stable.

Third, the needle

The needle is divided into a secant needle and a misting needle. The sizes of the needles are different. The commonly used needles are: secant round needles, which are divided into closed mouths and loose needles. It is a curved, straight row of needles,, etc. The needle size is generally 0.25, 0.30, 0.35 mm divided into a blunt needle and a sharp needle.

For the skin, the smaller the needle type, the smaller the force area on the skin, the smaller the resistance, and the easier it is to penetrate the skin. On the contrary, the force area is large and the resistance is large. It requires a greater pressure and machine strength to penetrate the skin. The requirement of the pattern effect determines the model and size of the needle. In the process of tattooing, how to pierce the needle into a reasonable depth, leaving the color, must understand the skin's toughness (tension) and thickness, the degree and frequency of the robot, the thickness of the needle to form the resistance and the pressure of the needle tip on the skin, the relationship between the four .
