VirtualReScan
Details

The purpose of document scanning is to electronically create accurate black-and- white images of original source documents. The originals may also be in black-and-white, but most likely they will feature colors, shaded backgrounds, reversed text or other elements difficult for a bitonal scanner to translate into crisp, clean, black-and-white images.

Without VirtualReScan, even the most skilled scanner operator must go t hrough a series of scans and rescans to obtain an acceptable image from a complex document. Even this process yields less than perfect results. And the more documents you have to scan, the longer and more costly this process is.

An alternative is to capture the document images as color or grayscale files. While this results in cleaner, more readable images, it also results in excessively large files as far as grayscale is concerned. Newer color file size compression has made color a good choice for scanning. However, grayscale files, in CCR's opinion, remain too large for rapid transport and storage over most conventional networks. Color file sizes can result in an average increase of 20 to 30%, but with the lower price of storage drives per megabyte, the increase is negligable.

However, VRS provides an ideal solution. It uses the 256 shades of a grayscale image to analyze and determine the optimum settings for each document. It then converts this image into a small, perfectly readable black-and-white image. Thus VRS gives you the best of two worlds: the highest quality black-and-white images with small file sizes.

How VRS Works

The beauty of VRS is that it is so simple to use. Most operations are aut omated to accelerate the scanning process, reducing the need for highly trained scanner operators.

• Reduced Document Preparation
  Simply place all your documents -- no matter their size, color or orientation -- into the automatic document feeder, hit the scan button, and away you go. VRS will automatically detect any paper jams, bent corners, or other equipment conflicts and alert you of the problem.
• Automatic Deskew
  VRS begins by automatically straightening each scanned image. This is particularly crucial when automated recognition techniques such as OCR and ICR are to be performed. VRS also allows operators to intercede and manually fine tune the skew angle of documents as necessary.
• Improved Image Clarity
  VRS analyzes the brightness and contrast levels of each document, comparing them to the user-defined acceptable range. Exceptions are automatically corrected or can be displayed to the operator for manual adjustment. In manual mode, the operator uses the on-screen view of the image to readjust clarity settings until the desired result is obtained.
• Eliminated Noise
  VRS lets the scanner operator further enhance the image by thinning or thickening lines and characters and removing excessive speckling -- all with easy-to-use slider controls. With noise reduction, you obtain crisp, clean images every time.
• Accelerated Scanning
  In high-volume situations where scanning speed is critical, VRS can be set to perform fast scanning at a lower dots-per-inch (dpi) resolution. After analyzing the image, VRS will then convert the final bitonal image into a higher-resolution dpi for better on-screen viewing.
• Real-Time Analysis
  VRS will display optimum settings for each scanned image to allow users to create new default settings for common documents. Thus, a form printed on difficult-to-read color paper can be scanned and analyzed so that the optimum settings for that type of document can be created and saved for future use. VRS lets you save multiple document profiles to accelerate the scanning process.

Two Flavors Meet Every Need

For production environments with large scanning volumes, a VRS-Ready scanner assisted by a Kofax Adrenaline board gives you the power to drive optimized documents through your system at 35 to 125 pages per minute.

For environments requiring high quality but lower volume (6 to 25 pages per minute), software VRS with a desktop or personal document scanner is the ideal solution. And the new Adrenaline 450, 650 and 650i SCSI scanner controllers provide the best way to connect that scanner to your PC.

For high speed color scanning solutions, CCR recommends the Kofax 650i card. This card works well with high speed color scanners such as the Kodak i800 series and the mid-volume Kodak color scanners such as the 4500 and 3590C scanner models.

Works with All the Leading Scanners

There are dozens of VRS Ready scanners available today and the list is growing. You can use VRS with scanners from Bell+Howell, Canon, Fujitsu, Hewlett-Packard, Kodak, Panasonic, and Ricoh.

Works With All the Leading Capture Solutions

VirtualReScan works with the hundreds of scanning applications built on the Kofax ImageControls platform, including Kofax Ascent Capture as well as applications from Captiva, Cardiff, Hyland, icomXpress, Microsystems Technology, and others. And Software VRS 2.0 also supports ISIS®- and TWAIN-based scan applications.
