Logistics labelling guide

Pallet labelling automation

Automated pallet labelling combines variable-data printing, controlled pallet positioning, label application and verification at the point where the logistics unit is ready to identify.

Identify the logistics unit

Define the pallet data and placement rule before choosing the applicator.

The data requirement comes first. Confirm the identifier, human-readable information, barcode format, customer rule and data source for each logistics unit. GS1 UK guidance states that pallet logistics labels should include an SSCC encoded in GS1-128 and that two identical labels are used on adjacent sides for a pallet application.

Use the current customer and GS1 requirements for the actual project. The GS1 UK page on where pallet labels should be placed is an authoritative starting point; final label content, dimensions and placement need to match the supply-chain requirement.

The machine must then reach the required faces while keeping the print engine, applicator, pallet and people within a safe, serviceable layout.

Pallet labelling inputs

Pallet type, load envelope and surface variation
Required labelled faces and position tolerance
SSCC and other data fields
Label size, material and adhesive
Pallet arrival orientation and stop position
Data trigger, confirmation and error response
Scanner, reject or hold requirement

System sequence

Control pallet presence, data association, application and release.

Present

Detect the pallet, confirm orientation and position it within the applicator's defined working envelope.

Associate

Receive or select the correct logistics-unit record and prevent printing when data is missing or ambiguous.

Print and apply

Create the label, apply it to the required face or faces and confirm the mechanical cycle.

Verify and release

Check presence or readability as specified, record the result and release, hold or divert the pallet.

Application design

Account for pallet and load variation.

Variable	Why it matters	Evidence
Pallet position	Changes the distance and angle between applicator and label face	Conveyor datum, stop tolerance and representative pallets
Load envelope	Overhang, underhang, wrap, gaps or uneven surfaces affect contact and adhesion	Normal and difficult loaded pallets
Label face	Adjacent-side application may require rotation, a moving applicator or a mechanism with controlled reach	Required faces, label position and line layout
Data timing	The correct SSCC must remain associated with the physical pallet	Upstream data event, pallet tracking and failure logic
Verification	Readable data may be required before dispatch or warehouse release	Scanner position, grading or presence rule and hold/reject method
Safety and access	Applicator movement and pallet transport create working-space and isolation needs	Site layout and competent risk assessment

Keep the SSCC associated with the correct physical pallet.

Data association can fail even when the label prints correctly. Define the point at which the pallet record becomes active, how the pallet is tracked to the applicator and what happens if a pallet is removed, reversed, delayed or replaced. Prevent the next record from advancing until the previous pallet's outcome is confirmed.

Use a controlled reject or hold state for an unreadable or missing label. The operator needs a safe method to inspect, reprint and reconcile the affected logistics unit without creating a duplicate identity.

See the print-and-apply guide for print and application fundamentals and the controls and sensors guide for tracking and fault response.

Acceptance checks

Correct data for each pallet record
Identical labels on required faces
Placement on normal and difficult loads
Barcode readability using the agreed method
Response to missing data or label
Safe reprint and reconciliation process
Recovery after stop, removal or restart

Design for exceptions without losing pallet identity.

Pallet flow is rarely perfectly uniform. Define the response to a missing pallet, incomplete load, damaged wrap, shifted load, unreadable existing label, reversed pallet or a pallet removed between data assignment and application. The system should hold or reconcile the record rather than silently advancing to the next SSCC.

Where two labels are required, confirm whether the machine applies both during one stop, through pallet rotation or through a moving applicator arrangement. The layout must allow the required faces to be reached while preserving conveyor control, guarding, access and scanner visibility.

Coordinate warehouse and production responsibilities

Agree where the pallet record originates, when it becomes final and which system records successful labelling. Production, warehouse and IT teams may each own part of the workflow. A clear boundary prevents a mechanically successful label from being released with an unconfirmed dispatch record.

Include manual recovery. Operators need a defined method to hold the pallet, inspect the data, remove or cover an invalid label where permitted, request an authorised reprint and confirm the final result before release.

Exception tests

No pallet at the expected trigger
Pallet outside the approved position
Missing or invalid data record
Printer or applicator cycle failure
Unreadable or missing label
Pallet removal and replacement
Authorised reprint and final reconciliation

Next step

Provide loaded pallet samples, label rules and data workflow for review.

Send the product, container, closure, label or outer-pack samples that represent normal and difficult production. Include the required task, current process, intended output, available space and any existing equipment that must remain.

Useful enquiry routes

Pallet identity

Verify the relationship between pallet, data, label placement and release.

Pallet labelling is an identity and handling task as well as a print-and-apply operation.

Define how the pallet is detected and stopped or tracked, which system supplies the label data, which faces require labels and what confirms successful application. Account for load overhang, wrap condition, board movement, irregular surfaces and the distance between print and application.

Use the inspection and reject guide to specify failed-read and uncertain-pallet responses. A pallet may need to stop, recirculate or move to a controlled review position rather than a small-pack reject bin.

How is a pallet label linked to the correct load?

A pallet label is linked to the correct load by a controlled identity event, data source and tracking sequence that remain associated until printing and application are confirmed. The project should define what creates the pallet identity and what happens if the label or load is removed, delayed or reintroduced.

Can one pallet labeller apply labels to two faces?

A pallet labelling system may apply to more than one face using movement of the applicator, pallet or repeated stations, but the required geometry and cycle must be confirmed. Provide pallet dimensions, load variation, conveyor position and the exact label faces and placement windows for engineering review.
