Angled Picket Fence Calculation
The number of complete scans for angled
picket fence is calculated the same as that
for picket fence, with the exception that the
scan width is shortened in proportion to
scan tilt.
• Scan Rate (SR) is the number of scans per second that a given scanner
is capable of emitting.
• Scan Width (SW) (picket fence formula only) is the width across the scan
beam, at a given distance from the scanner, in which a label can be read.
• Label Speed (LS) is the distance per second that a label moves as it trav-
els through the scan lines.
• Label Length (LL) (picket fence
formula only) is the length of the
longest printed label to be read
plus the length of the quiet zones
(figure 1-6).
• Label Height (LH) (ladder formula
only) is a measurement of the
height of individual bars (figure 1-6).
Note: While the formulas given here solve for the predicted number of scans,
you may also assign a value for number of scans (5 or more) and to solve for
other parameters that might be changed, such as scan rate (motor speed),
label speed, etc.
