A blunt needle is a relatively blunt angle of the pointer tip, generally about 20-30 degrees. It is squeezed into the skin when piercing, which is relatively difficult to pierce, but the needle point is larger, the performance color is more saturated, and it is more suitable for totem And color; sharp needle is the angle of the pointer tip is relatively sharp, generally about 5-15 degrees, because it is very sharp, it is easier to pierce, the needle point is small, the performance of the matte surface is very delicate, it is more suitable for sketching and traditional black and white .
The arrangement of round needle pointers is round, generally divided into loose round needles and gathered round needles; the arrangement of row needle pointers is in rows, generally divided into four types: single row, double row, fork row, and arc row needle.
One. Round needle:
1. Loose round needle: This kind of needle is generally a blunt needle. This needle type is evolved from a hand needle to facilitate bundling. The distance between the needle and the needle is small, the amount of staining material is small, the penetration is difficult, the coloring is slow, and relatively speaking, it is easy to skin damage.
Suitable for cutting thick lines or small areas of detail, it is better to use a fog machine, because the frequency of the fog machine is slower, and it will not be so easy to skin damage.
This kind of needle is gradually eliminated and used less and less, but it still has its irreplaceable benefits. Because its arrangement and shape make it easy to control and get started, so many novices use this kind of needle at the beginning. Also, because it is a blunt needle, the color is more saturated, but the needle pitch is too small, it is not very easy to pierce, we can use the trick described below to spread the needle pitch, like a tree branch, in When making small areas of color, there are unexpected effects.
2. Collapse the round needle: this kind of needle is usually a sharp needle, the distance between the needle and the needle is small, the amount of staining material is small, the penetration is easier, the coloring is faster, and relatively speaking, it is not easy to skin damage.
It is suitable for shaping all kinds of cutting lines or small areas of detail. When cutting lines, if it is a line with the same thickness from beginning to end, you need to use a cutting machine. If you need to change the thickness of the line, it is recommended to use a fog machine. Repeated retouching. When making small details, you need to use a fog machine. There is also a small trick, because the stitch length of the gathered needle is relatively small, it is not very good for coloring. If it is repeated many times, it is still easy to skin damage. At this time, we can use a lighter Burn the solder at the tip of the needle a little, then immediately quench it in iodine wine. At this time, you will find that the tip of the needle has spread out. The degree of spreading is the length of time you need to burn. You need to control it yourself. When the needle tip spreads out, the needle distance becomes larger, and it is easier to penetrate. The amount of staining material is also larger, so that the coloring is faster and the skin damage is smaller.
