Drum scanners are used to scan a document and produce it at a very high resolution rate. There is no type of scanner that will give you the kind of resolution, detail, sharpness, dynamic range and color rendition that drum scanning can give you. Given the high cost of producing such scanners, there are only a few companies that manufacture these scanners. It is considered a tremendous upgrade over the regular flatbed scanner.

A drum scanner is one that uses a photomultiplier tube (PMT) to scan images instead of the charge-coupled device typically used in a flatbed scanner. Photomultiplier tubes are vacuum tubes that are extremely sensitive to light. In drum scanners, the image is mounted on a glass tube.
