Prescale Film Working Principle
Two types of Prescale film exists. The first type is single-sheet, known as the Mono-sheet type. This is composed of a polyester base on which the color-developing material is coated, with the micro-encapsulated color-forming material laid on top.

The second type is double-ply, known as the Two-sheet type. This is composed of two polyester bases, one being coated with a layer of micro-encapsulated color-forming material and the other with a layer of color-developing material. The two bases are used together, with the coated sides facing each other. When pressure is applied, the microcapsules holding the color-forming material are broken, and this reacts with the color-developing material on the film.
