Kodak i5000 Series - Bar Pattern Details

6-10 A-61670 August 2014
Bar pattern details 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).
