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.

- Physical properties:
- Lighter in texture and lower in weight, it is easier to carry and transport than traditional coated paper, while reducing raw material consumption and cost.
- It has a certain degree of slipperiness and flexibility, which makes it easy to run and process on high-speed printing machines.
- Environmentally friendly: Because of the use of more environmentally friendly production processes and materials, lightly coated paper meets the demands of modern life in terms of sustainability and health while fulfilling the needs of printing.
