Product characteristics
The PSS Print Detector is primarily used in the packaging industry for verifying the pres‐
ence of prints, such as best-before dates, serial numbers, or 2D codes. They can, how‐
ever, also be used in any 1D pattern verification application.
The PSS compares a taught-in pattern with the following patterns; checks that they
match and checks for 100% correspondence to reduce deviations in contrast or length.
The sensitivity level, i.e., a print that is yet to be recognized as good quality, can be set
by the user.
•
10 - 30 coarse: Print is present.
•
40 - 60 medium: Print is present, but the quality is poor.
•
70 - 90 fine: Print is present, the quality is good, but details are missing.
