ACS Monochrome
APERTURE CARD SCANNERS The Contex ACS 4x00 Aperture Card Scanners are monochrome scanners for microfilm mounted on aperture cards. They are cost effective solutions for fast, high volume scanning and workstation engineering. The Aperture Card Scanners are available in either built-in automatic card feeder or single card feed models. Scanning Superiority
The ACS scanners automatically digitize drawings from E-Size/A0 to A-size/ A4 stored on aperture cards, and oversizes up to 59"x44", with reduction ratios from 37x to 7.5x. The punched Hollerith code in the cards can be used for automatic drawing size selection and file naming. You select the right resolution - 400, 300, 240, 200,150,100,75 or 50 dpi as measured on the unreduced document to match your requirements and storage capabilities. The scanners create raster files, with more than 50 formats selectable, compatible with virtually all third party software.
The ACS scanners are very fast, scanning up to 300 cards/hour, depending on the size of the unreduced document on the card. A typical D-size CAD drawing directly to RLC format takes 19 seconds at 200dpi.
Image Enhancement Power
The reliable and effective ACS scanners reproduce your images in high quality grayscale and crisp, clear black-and-white. The ACS scanner models support fast and reliable monochrome image enhancement techniques.
2D-Adaptive Thresholding is performed in real time with the hardware embedded Digital Signal Processor. The adaptive processing automatically compensates for varying background, faded areas and stains. The ACS scanner will give you clean crisp scans and printouts even from poor quality originals. Take image enhancement even further with speckle removal and hole-filling performed on-the-fly as you scan. Electronic deskew lets you automatically align your image for perfectly horizontally aligned drawings. When scanning with 256 graytone levels, you can interactively adjust brightness and contrast on-line.
Total Scanning Control
Scanning with the ACS scanner is controlled through the WIDEimage software with its two windows that enable you to interactively move around the drawing, as you preview expected results of settings directly on your screen. You can select image mirroring and image reversal to be carried out while you scan. WIDEimage supports the ASC scanners with user-friendly menus for setting your drawing size, automatic scaling, automatic file naming, batch scanning, Hollerith code interpretation and printing. WIDEimage supports all your scanning tasks including on screen viewing, zooming and measuring of relative distances.
The two ACS scanner models come in either manual feed or automatic feed versions.
