Do u mean what is a 3 round liner tattoo needle used for? The 3 represents how many needles total, and round means they are arranged in a circle as opposed to lined up beside one another, liner means it is used for making lines. A 3RL is most commonly used for tattooing very fine lines in small or very detailed tattoos or lettering.
You just said it yourself: Lining. Five rounds are used to create a finer, more delicate line though, but it also depends on how heavy handed you are. If you're heavy handed, then your five round lines could look like seven round lines.
Liners are grouped in a circular pattern which gives them their nickname, rounds. Used mostly for outlining tattoos, liners come in as small as a single needles and can generally reach up to an 18 round. Single needles are rarely used by most tattoo artists, except occasionally for very fine line work. The most common groupings for liner needles include 3, 4, 5 and 7, but you can also find needles grouped in 8, 9, 11, 13, 14, 15 and 18, and some suppliers even offer a 19 and 20. Some suppliers offer tattoo needles in assorted sizes which are commonly used in tattooing, just save your time by folllowing that.
chances are your outline is done by a 5 or 7 liner (5 or 7 needles grouped tightly together) and your shading/color fill is done with a 7 mag or 14 mag depending on size of tattoo
In almost all instances, one uses a 3RL, or perhaps a 7RL. All depends on the artist and the size of the piece.
The needle size does absolutely nothing for a tattoo machine. A needle to a machine is like a brush to the hand. Different tools for different needs. If you want mor information, get an apprenticeship under a skilled tattooist and they can give you more in depth information.
to do the outline on a tattoo you need a needle called a liner for instance you could use a 14 round liner. now for shading you need a shader which is another kind of needle now you can use a 14 round shader or a 14 flat mag shader that answer your question and an p.s you can get a needle any size they can go as small as 1 all the way up to a 49 flat and so on
It just depends on what you are getting and the size of it.It entirely depends on what tattoo you want to get and where you get it, so theres no real exact price.It depends on the size. Most tattoo shops charge a min. of $50 to cover cost of needles and ink.
7 or 9 magnum or a 14 round for heavy filling such as tribal .......
If your doing a full color tattoo, meaning just one shade i usually use a round shader, if you want to do transaction from light to dark i use a flat mag. Sizes all depends on what your comfortable with, for a large piece or tribal i use a 25rmag and a 5rs for tighter space. for the tip i use the same liner to fill in. but just try and see what works best for you. This is my advice I have 6 years of experience currently working as a tattoo artist. Some artist will agree or disagree with my advice.
depending on the size i would just use a 7RS big the shading area the larger i would use the 9RS or Flat Shader
The size of the needle and the size of the tip should match unless you are using bugpin needles, in which case the tip should be two sizes smaller than the needle.
