Kofax Barcode Settings

In the Recognition area barcode recognition is enabled by ticking the Enable checkbox.

If you additionally select the Learn option, an attempt is made to find the optimal settings for the height, width, proportion, and quality of the barcode. These settings are then entered in the settings dialog. The Learn option is useful if you use the same scanner with the same scan settings for identically structured scan templates. This option should be disabled after several test scans, as it considerably slows down the processing speed. The detected settings will be kept.

In the Bar Size area you can enter values for barcode width and height. The Height value should correspond to the barcode height. Entering precise values increases the processing speed. Larger or smaller barcodes will be recognized anyway.

The Width value defines the width of the narrowest barcode line. Entering exact values increases the processing speed. You need to choose the Any Width option if you cannot enter an exact value; otherwise the quality of the scans will be poor.

Tick the 2 to 1 Ratio checkbox to set the proportions. 2 to 1 Ratio means the broadest barcode line is twice as wide as the narrowest line. In case this option has not been selected, barcodes will also be recognized if their lines are three times as wide as the narrowest line.

If you use the same scanner with the same scan settings for identically structured scan templates, you can determine the value for height, width, and proportion with the Learn option in the Recognition area.

Use the options in the Search Direction area to define the orientation barcodes can have. 0 represents the horizontal orientation from left to right, 90 represents the vertical orientation top to bottom, 180 represents the horizontal orientation from right to left, 270 represents the vertical orientation bottom to top. Using multiple options significantly increases processing times.

Functions for patch code recognition will be ignored. Keep the No Patch Code setting.

In the Limits area, you can enter values for a barcode's minimum length and the number of barcodes.

• If you enter a value for Minimum Characters in Bar Code, barcodes with fewer characters will be ignored.

• If you enter a value for Maximum Bar Codes Per Page, barcodes will only be searched in a page until the value is reached.

• If you enter a value for Maximum Bar Codes Per Line, barcodes will only be searched in a line until the value is reached.

The Quality area offers the entries Good and Normal for good and lower-quality scan templates, respectively. The processing speed when Normal is selected turns out to be considerably lower, though fuzzy barcodes will be recognized better.

The last character of the barcode types 'Code 39', 'Interleaved 2 of 5', and 'Linear 2 of 5' may be a check code. Tick the Enable checkbox in the Checksum area to check whether recognized characters and the check code correspond to each other. If they do not match, the barcode will not be recognized. If you have not selected the Enable option, even though a check code is available, the check code character will be considered to be a regular barcode character.

The Type area offers a list containing supported barcode types. Select the barcode types to be detected in scan templates in the Available list. Click Add to add the selected barcode types to the list of used barcode types (In Use). Use the Remove button to delete list entries. In case multiple barcode types are selected, the width settings (Width in the Bar Size area) will be ignored.

Do not select barcode types which are unavailable in the scan template; otherwise the processing times will be unnecessarily increased.
