I'm working on digitalizing all the DVD covers and booklets I've got. There are two problems I'm facing:

- Since the DVD covers are printed with the CYM method, the picture looks really grainy, just like pictures scanned from newspapers: http://upload.wikimedia.org/wikipedia/commons/c/ca/KazimKarabekir.jpg

- The DVDs are partly a couple of years old, so they are not even anymore. When I scan them, this results in different color intensity.

Does anybody know any helpful tutorials or programs that can help me to enhance the quality of my scans so that the look somewhat acceptable?
