Part 3: Tattoo Machines 101
The tattoo machine is the essential tool of the tattoo artist, just as the brush is the tool of a painter, or the chisel the tool of a sculptor. Tattooists have not always been gifted with such elaborate mechanisms as they have today, but tattooing with any sort of precision has always required specialized tools.
All tattoo machines work by the same basic principles…
They are designed to allow the comfortable control of the path of the machine, while the machine moves the tattoo needles through a desired stroke length. The stroke length, together with the pressure you use, determines how deeply you tattoo into the skin. Different depths are used for different purposes, although only within a small range. Different machine types will also have somewhat different effects on needle penetration.
Given that all the machines work in much the same way, you might wonder if there’s really much point in going over the individual types…
However, while the practical differences may be subtle, they are definitely there, and experienced tattooists usually have a particular type they prefer. The most common type is the coil machine, which uses an electric current to activate anywhere from one to three coils, pushing the needle assembly forward. They are equipped with springs to push the needles back into starting position. Voltage regulation controls the speed of the needle, which can be varied within a wide range. They have the advantages that, because of the spring and the nature of the pushing force, they can respond to the tension of the skin you’re working on. They are relatively inexpensive, and there is a wide variety to choose from. However, they can only work by electric power, and they can be quite noisy relative to other types.
Rotary machines are a much newer type, with several advantages over the older coil type. They use a rotating drive system to move the needle assembly back and forth. They tend to be much lighter, perhaps causing less strain during long use. They are also much quieter than coil types, which can make the tattooing experience a bit more pleasant for both the tattooist and the client. Better-quality ones let out only a mild hum, compared to the loud buzz of a coil machine.
The other trait, which can be seen as either a benefit or a detriment, depending on your preference, is that a rotary’s way of working produces an absolutely consistent stroke length. They do not respond to the tension in the skin the way coil machines do. This can be a disadvantage for someone new to tattooing, as it can cause the needle to go too deep without good pressure control. However, for someone with great precision, it allows for more control.
Machines are also often differentiated by their purpose…
The two major types of machines are liners and shaders, and they are meant to do just as they say. Liners use closer-grouped needles and a faster movement for the purpose of making sharp details and lines with a single pass. It is important to only use a single pass with these machines, because doing more can excessively damage the skin. The other type is a shader, which can be used to shade with black ink, and is usually what is used for colored fills. Shader’s needles are wider-spaced and move slower so multiple passes are less damaging. Coil machines tend to come in one or the other type, but can be made to fulfill both functions. Rotary machines are usually both.
Rotary machines can also use pneumatic power, rather than electric. Pneumatic machines rely on an air compressor to work, but are extremely light. Rotarty, coil, pneumatic, electric, these are all possibilities for the tattoo artist, and you’ll have to find what works best for you. Of course, without ink, the machine isn’t worth much more to the tattoo artist than a paintbrush is without paint. Tattoo inks will be the subject of the next part in this series.
