Flatbeds add more depth
Article Abstract:
Buyers should know what to look for in color flatbed scanners that now have the color depth and density range capabilities to produce commercial-quality images. New scanners read 24, 30 and 36 bits. Density range, also known as dynamic range, has to do with the lightest and darkest tones the scanner will register. Some scanners use only one pass of the scan head to read images, while other use three passes, and the more effective method is still under debate. The optical, or real, resolution is an important consideration, as is interpolated resolution, which refines resolution by estimating images and enhancing the original scan. Color management systems allow the scanners to handle colors from different monitors, printers, and scanners. Flatbed scanners come with an interface kit, bundled software and hardware-based gamma correction. Information about 600-x-1,200-dpi color flatbed scanners and producers is presented.

Invitation to quality
Article Abstract:
Ten Macintosh and seven PC gray-scale scanners are reviewed, all costing under $8,200. Three printer-mounted scanners, which can be mounted onto dot-matrix printers, were also reviewed, but only one, the $299 Thunderware Thunderscan, made it onto the final list. Printer-mounted scanners are inexpensive but reproduction quality is indifferent. The $3,035 Dest PC Scan 2020 and the $3,495 Microtek MSF-300G tied for first place as PC-compatible scanners, and the $3,495 Datacopy Proscan 830 rated best for Macintosh users. The $8,195 Howtek Scanmaster offers excellent image reproduction but unless color scanning, as well as gray-scale, is needed the unit is not cost-effective. Flatbed scanners are recommended, unless the user plans to do a lot of optical character recognition scanning, and potential buyers should always find out if software, cabling, and hardware interface are included in the package.

The 300-word-per-minute-typist
Article Abstract:
Fifteen desktop OCR scanners costing under $10,000 and, for comparison, a human typist are tested for speed and accuracy on five documents: two multiple-page documents using monospaced typewriter faces, a single dot-matrix printed page, a single page in 10-point Times Roman printed on a Laserwriter Plus, and a three-column, typeset page. The $9,950 Kurzweil Discover 7320 Scanning System performed best. For the less expensive machines, the Dest PC and Mac had the first and second highest accuracy ratings, followed by, in descending order, Compuscan, Saba, Hewlett-Packard, Microtek, Canon, Abaton, IOC's Speedreader for the Mac, and Princeton's LS-300 for the PC. Buyer's Guide to PC and Mac OCR scanners included.
