Tattoo Needle Cartridge

Sterilize Your Equipment and Wash Your Hands
This step is vital to ensure safety for yourself and the client, given that you're breaking the skin and that blood will be present. This is one of the best ways to limit cases of contamination or infection of the area that you're tattooing, so always wear medical-grade gloves.

Assemble Your Equipment if You Haven't Already Done So
Depending on your experience, you will need to decide on what you're using. Often, you'll be buying the pieces individually or you'll be buying a kit. The good thing about a kit is that it's beginner-friendly.

Set the Needle Length
The needle will fit well into the slot designated for it. The needle shouldn't go any farther than two millimeters past the entry point of the tattoo gun. It should also go no less than one millimeter past the entry point.

Place Everything as You Need It
Having everything pre-placed limits mistakes. This should always happen before starting, and each ink cap you use should be within the barrier of all of the equipment that you've laid out.

Plug in the Tattoo Gun
Before taking clients, decide if you'll be using an analog or digital power source. You want to fine-tune the voltage as well before you put the needle close to the skin.

Start Pouring in the Ink You're Working With
Preparing the ink you need will involve having a different cap of ink for each color you're using. You will use the housing bottle to fill the ink caps and you should do your best to only let the needle touch the ink and not the actual cap.

Do a Test
The skin test is usually done 24 hours before the actual appointment, as this would be enough time to notice any adverse reactions. The test should be on a rarely seen area of the skin and should be a barely noticeable drop of ink. Tattoo ink allergies are rare but this should still be offered to the client.

Start Tattooing
Getting started might be harder than the setup process. That may only be if you haven't used a tattoo gun before. After putting everything together, getting started and finishing the design is all you have to focus on.
