[单项选择]Western tattooists work with a special electrical instrument, something like a dentist’s drill. It holds a number of very fine needles, which, for the purpose of reproducing the approved drawing, are dipped, in black ink. When the current is switched on, and the instrument passed rapidly over the outline, the action of the needles drives the ink into the skin. The tattooist is constantly wiping away excess ink as he works. This is where skill is so important, for the speed of the instrument means that he must work rapidly over lines which are almost permanently covered over.
The basic drawing then has to be colored in, using the same method but with non-poisonous paint now replacing the ink. The average tattoo contains four or five colors, each injected with a separate instrument. How many needles are used each time will depend on the area to be covered, but it is possible to use as many as ten or twelve, giving up to 3,000 injections a minute.
