READING FEATURES

3 READING FEATURES

3.1 ADVANCED CODE BUILDER (ACB)

In addition to linear reading, the A

dvanced Code Builder (ACB) allows code reading

by “stitching” together two partial reads of it. ACB is not as powerful as Advanced

Code Reconstruction due to limits on tilt angle, speed and Multi-label function; but it

is effective in the case of close-to-linear, small height codes, damaged codes, or poor

print quality codes.

ACB is used to read a code label when the scan line does not cross the label along

its entire length (excessive tilt angle).

Linear Reading

ACB Reading

ACB reads two fragments of a label containing a start or a stop character and a

number of digits, and puts them together to build the complete label.

ACB also has an intrinsic ability to increase the reading percentage of damaged

codes as in the examples below:
