Reflective thermal transfer printing label manufacturing method, single-color reflective label and multi-colors reflective label

A single-color reflective label, comprising:

• a reflective layer, the reflective layer having a plurality of beads, wherein the plurality of beads includes a display surface and a reflective surface, and the plurality of beads is arranged on the reflective surface, such that the reflective surface of the plurality of beads faces a same side, and the plurality of beads is partially reflective and optically transparent, and the reflective surface is selectively coated with a metal material;
• a first ink layer, wherein one side of the first ink layer is arranged on the reflective layer, the first ink layer is printed on a first release element with a first hollow pattern, wherein the plurality of beads is only arranged on the first hollow pattern and is formed on one side of the reflective surface, the first ink layer has a first color;
• and
• a glue layer, wherein the glue layer is provided for stacking on another side of the first ink layer or fusing to the first ink layer;
• wherein when an external white light is incident on the display surface, the white light is reflected by the reflective surface to form a first emitted light of the first hollow pattern, and when the reflective surface is partially reflective and optically transparent, a wavelength of the first emitted light is determined by the first color, and when the reflective surface is coated with the metal material, the wavelength of the first emitted light is determined by a characteristic of the metal material.

A multi-color reflective label, comprising:

• a reflective layer, the reflective layer having a plurality of beads, wherein the plurality of beads includes a display surface and a reflective surface, wherein the plurality of beads is arranged on the reflective layer, such that the reflective surface of the plurality of beads faces a same side and the plurality of beads is partially reflective and optically transparent, and the reflective surface is selectively coated with a metal material;
• a first ink layer, wherein one side of the first ink layer is arranged on the reflective layer, the first ink layer is printed on a first release element with a first hollow pattern to form a first hollow pattern with the plurality of beads, wherein the plurality of beads only arranged on the first hollow pattern and is formed on one side of the reflective surface, and the first ink layer has a first color;
• a second ink layer, wherein the second ink layer is arranged on one side of the first ink layer, the second ink layer is printed on a second release element with a second hollow pattern to form the second hollow pattern without the plurality of beads, wherein the second ink layer has a second color and the second hollow pattern is a part of the first hollow pattern or the second hollow pattern is independent of the first hollow pattern;
• and
• a glue layer, wherein the glue layer is provided for stacking on another side of the first ink layer or fusing to the first ink layer;
• wherein when an external white light is incident on the display surface, the white light is reflected by the reflective surface to form a first emitted light of the first hollow pattern and the white light is reflected by the second ink layer to form a second emitted light of the second hollow pattern, and when the reflective surface is partially reflective and optically transparent, a wavelength of the first emitted light is determined by the first color, and when the reflective surface is coated with the metal material, a wavelength of the first emitted light is determined by the second color.
