you can do it a needle or a tattoo
needle
Yes you can, just use a needle or guitar string just make the same action with the needle as a regular tattoo gun would (up and down)
Between your epidermis and your dermis.
Any sewing needle will do. you can also use guitar strings and sand the with sandpaper to make them work.
Tattoo guns, or tattoo machines, work by using electromagnetic coils to create a circuit that rapidly moves a needle up and down. The needle punctures the skin at a controlled speed and depth to deposit ink into the dermis layer, creating the tattoo. The speed and depth of the needle can be adjusted to achieve different tattoo effects.
You can if you need to, but I would not recommend doing this for a whole tattoo. Not that there is anything wrong with it per se, but you are taking at risk unneeded trauma to the skin with this configuration as opposed to using a nice tight Round Liner.
yea it will hurt like hell but yes u cn do it
technically yes, you could scar the body in a designed manner. But no, you cannot really get a tattoo with pen ink. You will most likely get ink poisoning
About the width of a dime. Remember, you are only wanting to go halfway down the dermis. You have seven layers of skin, so you want to go down only three to four layers at most. Going to far will make the ink blurry and will create scarring...not going deep enough will make the ink fall out.
To stop cross contamination, or the spread of disease. For example, if the first person to get tattooed with a needle has HIV or hepatitis, the second person to get tattooed with that needle is at high risk of contracting those diseases. Always make sure the artist opens the needle in front of you.
A tattoo needle has no set speed. You the artist sets the speed using the contact screw on the Tattoo machine, as well as adjusting the voltage. If you set the needle speed to slow it can puncture the skin rather then pierce it, causing more blood to seep through the skin making it harder for the ink to stay in the skin. If you set the needle too fast it can cause the skin to tear or even mulch. Essentially turning the outer layers of skin to a hamburger ( Ground Beef ) like state. This will cause scarring to the person receiving the tattoo, and the ink will not set properly leaving the tattoo discoloured and possible disfigurement. So make sure you set your speed carefully. I tend to have mine set to what I guess at Approx 10 ~ 15 DPS ( drops of the needle per second ) I hope this helped!
