codes
Kodak Capture Pro Software can recognize patch codes as separators between batches or documents on your scanner.
1. Select File>Job Setup. The Job Setup dialog box will be displayed.
2. Select the job from the Job Name drop-down list that requires patch code separation.
3. Open the Capture tab and select Separation>By Patch Code.
4. Select the patch type you want to define: Patch 2, Patch 3 or Patch T. The Patch Code window will be displayed. You can enable as many of the patch code types as you need.
5. Click Detect Patch.
6. If desired, check one or both of the following options: Alternatively search on 180 rotated images and/or Alternatively search on back.
7. Under What to do if a patch code is selected, check either the Document Separation or Batch Separation.
8. Check any other desired options.
9. Click OK.

Overview
To use bar codes or OCR for separation or indexing in your job setup, you must do the following:• Select the Page Setup that will be used when scanning into this kind of job.
• Edit the job setup.
• Scan a page to use as a template for defining your bar code or OCR.
• Define where on the template image the bar code or OCR zone will be found.
• Specify how a correct bar code or OCR value will be recognized.
• Set up the actions connected to that bar code or OCR zone (e.g., create a new batch, create a new document in the current batch or populate one or more index fields).
This chapter explains these steps, except for populating index fields.
Populating index fields can be found in Chapter 4, Job Setup.

Using bar codes
Bar coding is a method of encoding data in a machine-readable code consisting of a parallel arrangement of dark and light elements. The light elements are referred to as “spaces” and the dark elements as “bars.” The bars and spaces are either wide or narrow. The combination of wide and narrow bars and spaces is a bar code. Each bar code begins with a “start”character and ends with a “stop” character. The industry uses bar codes to provide more accurate and efficient data input than is possible using manual data entry.
Bar code setup allows you to define the:
• name of the bar code
• data mask or syntax
• physical location where to find the bar code (in a zone or anywhere on the image)
• bar code type (width, height, quality and confidence level)
• level where you can find the bar code (batch, document or page level) Follow these tips to maximize the performance of Kodak Capture Pro Software:
• Choose the Page Setup name that you will use for scanning before you define a bar code zone.
• Make sure that all glass surfaces (the glass guides or glass over the camera area) within the scanner transport are clean. Dirty surfaces cause poor read rates.
• Use a higher resolution to obtain better read rates (300 vs. 200 dpi).
• Check the positioning of the zone around the bar code; it can affect the confidence level of a bar code. Leave at least a 1/4-inch of space around a bar code to guarantee that the full bar code will always fall within the zone.
Move the zone around the bar code until the highest confidence rate is achieved.
• The minimum bar code height specification is 40 pixels. At 200 dpi, 40 pixels is 20/100ths of an inch; at 300 dpi, 40 pixels is 13/100ths of an inch. For bar codes smaller than 40 pixels in height, specify a bar code height in the Bar Code Zone Setup dialog box.
• Verify that the correct bar code type and bar code orientation are selected in the Bar Code Zone Setup dialog box.
• If bar codes are on documents with color backgrounds, you may need to lower the threshold value in the Bar Code Zone Setup dialog box for improved read rates.
• If possible, use medium or low density bar codes. High density bar codes may require a lower Threshold value in the Bar Code Zone Setup dialog box.
• To achieve better read rates on more difficult bar codes, lower the Quality level in the Bar Code Zone Setup dialog box.
• When using Anywhere bar code zones, use a PC with a 2.8 GHz processor or higher. This will ensure Kodak Capture Pro Software’s ability to scan at scanner rated speeds when bar code reading is enabled.
