* Inconsistent Ink Flow: The extra space around the needles within the tip can cause inconsistent ink flow. Ink might pool around the needles instead of flowing smoothly onto the skin.
* Messy Application: The inconsistent ink flow can result in blotchy lines and uneven shading. You're less likely to achieve clean, crisp results.
* Increased Risk of Blowouts: Inconsistent ink flow can result in you pressing harder into the skin to ensure the needles are going in which can then result in a blowout.
* Potential Needle Damage: While less likely, the needles might have slightly more play inside the tip, potentially causing them to bend or break more easily, especially if you apply excessive pressure.
* Difficulty Controlling Needle Depth: The lack of a snug fit can make it harder to control the needle depth accurately.
Best Practice:
* Match Needles to Tips: Always use the correct tip size for your needle configuration. A 7 needle cartridge (or needle grouping if you're soldering your own) is best paired with a 7 tip.
* Proper Fit is Key: The needles should fit snugly within the tip, allowing for smooth ink flow and accurate needle placement.
In Summary:
Although it's technically possible to use a 7 needle configuration in an 8 tip, it increases the likelihood of messy results, inconsistent ink flow, potential skin damage, and less control over your tattoo. Using the correctly sized tip for your needles is essential for professional results and client safety.
