Shading
Once the outline is complete, the area is thoroughly cleaned with antiseptic soap and water. Then, the outline is thickened and shading is added. The tattoo artist will use a combination of needles. If this isn't done correctly, shadowed lines, excessive pain and delayed healing will result. Again, everything must be autoclaved before use.

Using a thicker, blacker ink, the artist goes over the outline creating an even, solid line. Shading creates special effects. Each tattoo artist works differently, depending upon his or her training and preference.
