Lighter areas that create the popular worn look of jeans are worked into the fabric by hand in traditional jeans manufacturing. Not only is this very time- and labor-intensive, but it also uses a lot of chemicals. 

Instead of working design highlights into the denim fabric by hand, laser technology makes it possible to create that special look without any manual labor at all. It uses light and heat to process the surface of the fabric, revealing the white core of the yarn.
