Two-sheet Prescale Film: Prescale Film is composed of an A-Film, which is coated with a micro-encapsulated color-forming material, and a C-Film, which is coated with a color-developing material. The A-Film and C-Film must be positioned with the coated sides facing each other.
Mono-sheet Prescale Film: The color-developing material is coated on a polyester base, with the micro-encapsulated color-forming material layered on top.
When pressure is applied, the microcapsules are broken and the color-forming material that is released reacts with the color-developing material to generate color. Through Particle Size Control (PSC) technology, the microcapsules are designed to react to various degrees of pressure, releasing their color-forming material at a density that corresponds to the pressure.
