Note
: Raster scanning is almost always done with picket fence labels.
Maximum raster height is 0.38 inch at 10 inches.
Angled Picket Fence Orientation
The problems associated with picket fence can be minimized by slightly tilt-
ing the scan line (figure A-5). This allows a larger portion of the label to be
scanned and increases the label placement area by “simulating” the ladder
orientation. This of course is impractical with a short bar code height.
Angled picket fence is recom-
mended only where the bar code is
reasonably tall and the label speed
is not too fast in relation to the scan
field width, since angling the label
will reduce the number of scans on
the label.
Note
: Since raster lines will cross
most picket fence labels several
times, there is typically no advan-
tage to angled picket fence in con-
nection with raster scanning.
