Bar pattern details Patch Codes Patch 2 Assigns image level 2 to the current document. A patch is a pattern of parallel, alternating black bars and spaces that is printed on a document. In order to prevent other document data from being detected as a patch, the scanner will only recognize a correctly formed bar pattern as a patch. The width of bars and spaces between the bars need to be very tightly controlled to ensure that the scanner detects the bar pattern. The wide bars should be 0.20 inches (5 mm) wide + 0.01 inches (0.25 mm). The narrow bars and spaces should be 0.08 inches (2.03 mm) wide + 0.01 inches (0.25 mm). The maximum width of the patch code is 0.80 inches (20 mm) + 0.01 inches (0.25 mm). The minimum overall length of the patch bars is 2 inches (50 mm).

controlled to ensure that the scanner detects the bar pattern.
