Desktop drum scanners can't be beat

Article Abstract:

Drum scanners offer a range of advantages to users including convenience, versatility, quality and cost-effectiveness. Drum scanners are distinguished from other types of scanners by their ability to handle large originals, scan reflective art and transparencies in the same batch, perform more functions earlier in the process and their higher productivity rate. The need for additional training and precision are the only potential disadvantages. Hardware for these scanners typically includes an interface, support SCSI or GPIB, optional spare drums and a mounting station. Factors to consider when comparing drum scanners are color depth, density range and optical resolution. Hardware features central to a scanner's performance and price that a buyer should consider include light source, focus control and aperture settings. Drum scanners work with PCs, Macs, and in many cases Unix, and they come with bundled software capable of basic operations. Additional software is necessary for more sophisticated image-processing.

Step up to linotronic typesetting: six ways to improve your image

Article Abstract:

If a program will work with a Postscript-equipped laser printer, it will work, though more slowly, with one of the Linotronic series of Postscript phototypesetters. Thus, when quality typography is needed, resolution can be increased from 300 dpi, which is characteristic of a laser printer, to 1000- or even 2000-dpi output, using an L100, L300, or an L500 device. Using a Linotronic machine requires no expertise, and in fact, you need not own one; time on one can be rented. Tips for using a Linotronic machine to prepare a document are listed and discussed: check compatibility; match your fonts; take advantage of a page's full image area; anticipate differences in hairlines, screens, and spaces; choose graphics that will save printing time; and, if meeting a tight deadline is a problem, especially if your service bureau is inexperienced at Linotronic typesetting, allow extra time for a project.

Double vision

Article Abstract:

Features to consider in the selection of large-screen color monitors that are compatible with both Apple Macintosh and IBM PC-type microcomputers are discussed. There is an increasing number of 19-to-21-inch color monitors that can be used with both computer systems, and the monitors' prices have decreased to the $2,000-to-$3,000 range. Criteria to consider in selecting such a monitor include sufficient screen frequency range for the resolution desired, color bit depth, dot pitch, type of metal grid used by the cathode ray tube, the number and variety of controls, a memory for recalling preset or user-defined control settings, compliance with Sweden's MPR II electromagnetic emission standards, computer connections and adapters. A directory that lists the name, size, resolution, dot pitch and price of 24 dual-performance color monitors is included.
