Large format scanners are commercially available in a wide range of prices from very low to very high, depending on the quality, speed, resolution, format width, imaging technology, manufacturer, and so on. Color scanners are much more expensive than black and white scanners. For example, while Calcomp offers basic black and white and gray scale scanners at $9,900, their color scanners start only at $12,000 and the higher end models are very expensive (above $30,000). Some of the high-quality scanners, like the Cruse reprographic scanner, are intended for use in libraries and museums only.
