Abstract
Proposed are a thermal transfer ribbon and a sticker printing method using the same, which can form not only full-color images formed by a color ink part but also points, such as pearl, fluorescent, luminous, sparkling, glass, and metal glitters. The thermal transfer ribbon includes: a color ink part having a yellow ink part (Y), a magenta ink part (M), and a cyan ink part (C); an overlay part forming an overlay layer to protect a printed surface; and at least one point ink part provided between the color ink part and the overlay part.
