Appendix A

Printing

•
Product/Case Weight
Depending on the weight on a case, tamping may have to use less force
or even a different application method to safely apply labels.
•
Data Availability
SLPA parallel processing requires that data for multiple labels be in the
printer at all times. If data comes in less frequent, some of the internal
processes will be left idle, wasting time and increasing total label time.
•
RFID Operation Requirements
Optimum application rates assume that RFID encoding is the only
function being performed. Adding an RFID read and/or verify will add time
to a total label cycle.
•
Consistency and Timing of Product Arrival
All SLPA performance statistics require some degree of consistency in
product arrival rates. There has to be some minimum times between
apply signals. The number of cases that pass the applicator in a minute
does not determine the case rate of a system. Instead the rate is
determined as a function of minimum time elapsed between the arrivals of
two adjacent cartons.
•
Tamp Distance
For maximum performance, products should be justified to the edge of
the conveyor nearest the SLPA. The further away the boxes are, the
longer the tamp time. As tamp time increases, SLPA cpm performance
decreases.
