Light weight Coated Paper (LWC) is a type of printing paper that undergoes a special coating treatment during the papermaking process. It is machine coated with a thin and uniform layer of coating (usually containing pigments, adhesives, and other additives) on the base paper to improve the smoothness and opacity of the paper surface, and to enhance its ability to absorb and adhere to the ink, to achieve a good printing effect.
