Surface of Carbonless Copy Paper

Reflected Light Illumination


Carbonless copy paper relies on a chemical reaction to produce a color. One side of the sheet of paper is coated with micro-capsules of one reagent and the facing side of the adjacent sheet of paper is coated with the other reagent. Pressure ruptures the micro-capsules and the resulting reaction produces the color copy of the pressure pattern.
