How to choose a barcode module versus a separate verifier
The camera barcode module takes out broken bars and an occupied quiet zone on each piece. An ISO/IEC 15416 grade needs aperture, wavelength, and more than one scan.
The barcode module in the camera is for taking out each piece with a broken bar or an occupied quiet zone. An ISO/IEC 15416 grade needs an aperture, a wavelength, and more than one scan. Without those, buy a separate verifier and sample with it. Do not treat the camera as a verifier just because you want a letter grade.
Why it is judged this way
If the retail customer wants grade C or better, the order rules. The report comes from a verifier, or from a system that is written as calibrated to ISO/IEC 15416. If you only need to take out a code that cannot be read, the camera module is enough. Do not buy it at a verifier price.
What to compare
| What you see | What to call it | What not to do |
|---|---|---|
| You only need to take out broken bars and quiet-zone faults | Camera module | Budget it as a verifier |
| You need an ISO/IEC 15416 grade | A verifier, or a calibrated system | Use a letter that does not state the aperture |
| You need both | Two lines on the quote | Mix them into one pass |
At job change or when a roll is opened
- Ask whether the customer wants a reject or a grade.
- If a grade, ask the aperture, the wavelength, and the number of scans.
- Split the quote into two lines.
