Touching up the grays

Article Abstract:

Z-Soft Corp's Publisher's Paintbrush 1.5 is a gray-scale scanning and editing program that lets desktop publishers enhance or alter a gray-scale image or achieve special effects. The $285 PC-compatible program requires 640Kbytes, Dos 2.0 or a later version, two floppy disk drives, and a VGA-compatible graphics card. An analog monitor is required to view gray scale, and EMS memory and a hard disk are recommended. The program uses expanded memory, which makes it easier to work with an entire image on screen, but its image editing functions are limited, and the program's file format is not yet compatible with other applications, so gray-scale scanned pictures have to be converted into inferior-quality images before they can be imported into PC Pagemaker or Ventura Publisher. Until these problems are solved, the program's flaws outweigh its excellent image control capabilities.

Amazing grays

Article Abstract:

Gray-scale scanners now make it possible for desktop publishers to improve their production of halftones by scanning for different values of gray, instead of just black and white. This produces a clearer, more professional reproduction. Gray-scale scanners can be obtained for $2,000 to $4,000, but to optimize scanner use a publisher will need expensive accessories, including sophisticated software, a powerful computer, additional memory, an analog monitor, and access to a PostScript-compatible typesetter. Gray-scale scanning is recommended for publishers who send their files to print shops via modem, users who want to use electronic imaging capabilities that are present in gray-scaling tools, or publisher's whose goal is the complete digital composition of publications.

Invasion of the flatbeds

Article Abstract:

Flatbed color scanners are evolving into more and more affordable, legitimate alternatives to drum scanners. Both types of scanners convert reflect images and transparancies into digital data, but flatbeds do this via charge-coupled devices that consist of thousands of tiny elements that transform light intensity into digital information. Drum scanners perform this transformation using photo-multiplier tubes, which utilize a photoelectric cell to analyze the light. Flatbed scanning technology has advanced so far as to render it nearly equal to drum scanning for top quality color.
