generic and specific artwork is imparted to plastic discs such as cds , cd roms , and dvds by exposing a layer of photoresist material on a forming member , which already contains generic artwork , to light from an original image of specific artwork . the material of the photoresist layer is exposed to different depths by different intensity light from different specific image regions . where the image is dark , the exposure is to relatively shallow , random depths . where the image is light , the full thickness of the photoresist layer is exposed . development of the photoresist layer removes the exposed photoresist material . the surface features of the developed photoresist layer and any uncovered forming member surface are transferred to a second forming member used in forming a surface of the plastic disc , thereby visibly embossing both generic and specific artwork in the disc .
