In-Line vs. Off-Line Label Inspection

Customers face fines, supplier disqualification, and damaged reputation when erroneous labels escape into the supply chain.

Off-line label spot checking can guarantee the quality of a new label, and can assess the quality of production labels over a given period of time, but do not catch individual errors that may occur during production, such as misprints, printer maintenance problems, debris or foreign matter entering the line, improper movement of goods, or sequential data printing errors. When production errors are discovered using off-line spot checking, entire runs of labels (since the last label that was verified for quality) may need to be inspected and discarded costing time and money.

Some customers, however, don’t believe in-line inspection is as reliable as off-line, due to uncontrolled barcode verification conditions during production, so many implement off-line only.

Without in-line inspection and barcode verification, however, label production operations are essentially running blind and there is still significant error potential that can lead to serious costs and other negative impacts.

This white paper provides information about in-line and off-line inspection and the risks of off-line-only label verification, and also discusses:
- Costs associated with poor-quality labels;
- Common causes of poor-quality labels;
- Implementation of a verification system to eliminate poor-quality labels;
- In-line and off-line inspection systems;
- Advantages of implementing an in-line label inspection system.
