Rework vs. Cover-Up
Clients often get these confused. A Cover-Up is designed to hide an unwanted tattoo completely. A Rework is for when you still like the original idea or design, but the execution needs saving.
Re-lining
Sharpening blown-out or faded lines to make the image crisp.
Re-coloring
Packing fresh, high-quality pigment into faded areas to restore vibrancy.
