Printing process:
It is through textile screen printing, its photochromic ink changes color when exposed to sunlight or UV light. In its natural state they are colorless and “invisible” (so you will have two garments in one white and with a spectacular print), when they are exposed to heat they become visible. They are reversible inks because they return to their original colorless state, once they are removed from the light source.
The appearance/disappearance of the color is faster and more spectacular when exposed directly to sunlight than under 365nm UV lamps. Its color change is blue. This makes it a unique garment because it can be verified immediately, and does not require any special equipment, just exposure to sunlight.
