That's correct. 48 bits is 16 x 3 (for RGB). However, i don't know of any desktop scanner that gives you 16 bits per color. The Niko 4000ED, Polaroid Sprintscan 4000+, SS45 Ultra SS120 all give you 14 bits and of course the higher the bit count the better the dynamic range of the scanner ( theoretical maximum 4.2 Optical Density). The Nikon IV and Polaroid ss4000 and SS35 Plus give you 12 bits per color.

Simon, That would be 8 and 16 bits/channel so 8/16 bit for grayscale and 24/48 for RGB. "16 bit RGB file" is not very precise but they mean 16 bits/RGB channel. 8 bit output = 8 bits/channel.
