Scanning Lab
The NMRLS Scanning Lab consists of 2 dedicated workstations each with their own scanner. Both stations are networked to the NMRLS server and data is backed up both internally on each PC and via a networked tape drive. Descriptions of the individual workstations and their features follow.
Scanner Station
This workstation consists of a planetary grayscale scanner (Minolta PS7000) and a PC. A planetary scanner has they scanning elements in an overhead unit that does not come in contact with the item being digitized. The scanning takes place at an extremely fast rate and is similar to a camera flash. The Minolta PS7000 controls can be operated at the PC using the mouse, or by buttons or foot-pedals on the scanner itself.
This scanner has a built-in cradle to accommodate a book's spine and can scan left and right pages individually or single items up to 17 by 24 inches. One of the most useful features of the Minolta PS7000 is its ability to compensate for the curvature of a book's spine or undulations in flat work. It essentially flattens the image. This is extremely useful when scanning fragile maps or photographs mounted on warped backing boards as there is no need to place a sheet of glass on the image to flatten it out, the scanner takes care of this digitally!
The Minolta PS7000 is only able to scan items as black and white text or 8-bit grayscale. Grayscale is visually similar to a black & white photograph. The Minolta PS7000 does not scan items in color. This workstation is used as the primary scanning station, with image editing taking place on the more powerful PC of the Imaging workstation. Images and data can be burned to CD on this station using Roxio Easy CD Creator.

Imaging Station
This workstation consists of a flatbed scanner (Visioneer OneTouch) and a PC. This workstation is the primary image editing station with a powerful Pentium IV PC with 1 gigabyte of memory as well as a 32 MB video adapter and two 40-gigabyte hard drives. There is the choice of four image-editing programs as well as a batch process image-editing program. The primary image editing software available is JASC Paint Shop Pro and Adobe Photoshop. The batch processing program, JASC Image Robot, works in conjunction with Paint Shop Pro and can perform simple editing such as resizing images and changing resolutions, to converting images to other file formats and even enhancing image contrast, sharpness, and brightness. Image Robot can doe this for hundreds of images at once saving a tremendous amount of editing time spent on individual images. Images and data can be burned to CD on this station using Roxio Easy CD Creator.
