The opposite of that is kinda how I thought tattoo machines worked as a kid- as in with hollow needles and an ink cartridge, like fountain pens, and each poke into the skin would deposit ink that way. I even ‘figured out’ that the tiny vacuum from pulling the needle out would be what pulled the ink down into the skin.
When I found out how tattoo machines actually worked, it seemed so messy (and loud!).
IKR? But yeah, nah, tattoo machines are basically a motor that pumps the needle up and down, and you have to dip it in ink to transfer it into the skin.
Tattoo needles are more like the nib of a fountain pen than a syringe; the ink isn’t shot down through the needle, but suspended at the end of it when an artist dips the tool into a well. Then, when the tip of the needle pierces a hole in the recipient’s skin (both the epidermis and the dermis beneath it), capillary action—the same force that makes liquid creep up the sides of a straw—draws the ink down into the dermis.

That’s not how they work?
