Selecting A Flatbed Scanner

1) The number of elements in the CCD array.

2) Dynamic range.

3) The size of the scanner bed.

4) The color channel bit depth.

5) The pixel capture resolution.

These specifications seem straightforward enough, and just a few years ago they could be used to neatly categorize scanners into low, midrange and high ends—along with price, the bundled software and a few other things. It's not quite as easy today, as some low-priced scanners now rival far more expensive machines as far as the published specifications are concerned.
