Scanning modes
The digitized images can contain up to 4000 dpi (dots per inch) of image information. Color is achieved with a tri-color CCD in combination with a cold cathode fluorescent light source. Two modes are available:
•8-bit mode: Each dot can be represented by an 8-bit RGB code per color, resulting in 256 levels of gray, or 16.7 million colors. The original is scanned at 12-bits per channel, and the results are optimized to 8-bits per channel to produce a 24-bit RGB image.
•12-bit mode: Each dot can be represented by a 12-bit code per color, resulting in 4096 levels of gray or 68.7 billion RGB colors.
