Understanding Tattoo Cartridges and Safety Tips

Understanding Tattoo Cartridges

Tattoo cartridges, sometimes called tattoo needles or tube assemblies, hold the actual needle that penetrates the skin and deposits ink. They come in a variety of groupings and configurations, referred to as liner, shader, etc. When selecting tattoo cartridges it's important to consider the design you wish to tattoo and choose an appropriate needle type.

Reading Tattoo Cartridge Information

Most cartridges are labeled with information to help identify size and configuration. This usually includes the number of needle groups, the number of needles in each group, and the gauge or diameter of the needles. For example, a 7RL would indicate a 7 round liner grouping with 3-4 needles, while a 14RS would be a 14 round shader with 6-8 needles. Understanding this terminology is key to selecting the right tattoo needle.

Safety Considerations

When using tattoo cartridges it is critically important to follow all hygenic and safety guidelines to prevent infection. Sterilize equipment properly, wear gloves, use new needles, and maintain a clean environment. Consult local regulations and training guides for best practices to keep both the artist and client safe.

FAQs

What do the numbers and letters on a tattoo cartridge mean?

The numbers and letters indicate the cartridge configuration. The number refers to the groupings of needles, while the letters indicate the type of needles: RL = Round Liner, RS = Round Shader, M = Magnum, etc. So a common 7RL cartridge would have 7 round liner needles grouped together.

How can I tell what size needles are in the cartridge?

Needle gauge/diameter is usually also listed on the cartridge packaging or barrel. Standard sizes range from 10 gauge at the largest to 18 gauge at the smallest. Lower gauge = thicker needles. Match needle size appropriately to the tattoo location and details.

What kinds of tattoo cartridges do I need as a beginner?

As a general rule of thumb, beginners should start with round liners, usually 7RL to 9RL cartridges. These allow for practice with basic line work and designs. Later you can expand into different configurations for shading effects and details.

How should I care for and store tattoo cartridges?

Sterilize tattoo cartridges in autoclave pouches and store them sealed until use. Discard immediately after one use. Never attempt to reuse or sterilize used cartridges. Use caution when handling to avoid damaging the delicate needle groupings.
