Absolute Rainbow Dots
Absolute rainbow dots are used to detect errors caused by scratches, and whether any fading has occurred. Absolute rainbow dots are predefined dots carrying a unique value. These dots can be inserted in the rainbow picture in pre-specified areas. If fading occurs these dot values will change accordingly, and at the reproduction stage this can be checked and corrected. Absolute rainbow dots will be microscopically small so that they occupy very little space in the rainbow picture. These will be colored differently so that each dot will have its own fixed unique value.
