Tamp
A pneumatic or electric pad carries the label and presses it onto the package; a sensor detects package height so varying cartons are labeled consistently.
Labeling automation
Print & apply labeling automation
Variable-data labels printed and applied in line, then verified: shipping and carrier labels, GS1-128 SSCC case and pallet labels, retail compliance labels, and pharmaceutical serialization. We build the controls and integration that make it accurate at line speed.
Application methods
How labels are applied
The right method depends on the package, the face being labeled, and the line speed.
Tamp-blow
The pad moves close to the package and a burst of air places the label the last short distance, reducing contact force on lighter or uneven products.
Air-blow
No contact at all: the label is blown onto the surface, suited to fragile, soft, or moving products.
Wipe-on
The label is fed and wiped on as the package passes, for high speeds on consistent, flat surfaces.
Corner-wrap / two-panel
One label wraps around a corner onto two adjacent faces, a common approach for GS1 logistic labels that must be readable from more than one side.
Front, side & top apply
Applicators arranged for the face the label must go on, including leading or trailing panels as cartons move.
Pallet label applicators
Labels applied to two or more sides of a pallet load, following GS1 logistic label placement guidance, often with height-adjusting stands.
Poly bags & mailers
Print-and-apply for soft, irregular packaging, using gentle application methods and secure hold-down.
Print technology
Print technologies & systems
Thermal transfer
Prints through a ribbon for durable, smudge- and heat-resistant labels; the usual choice for long storage, cold chain, and abrasion.
Direct thermal
No ribbon; heat-sensitive labels darken directly. Simpler and lower cost for short-life shipping labels, but more sensitive to heat and light.
Print engines
OEM print engines such as Zebra ZE511/ZE521, SATO S84/S86-ex, and Honeywell PX series are the printing core inside many applicators, so they’re standardized and easy to replace.
Complete applicator systems
Integrated printer-applicators combine the print engine, applicator, sensors, and controller in one unit with defined I/O and network interfaces.
Data flow
From trigger to verified label
- Triggerscan or DWS
- DataWMS / WCS / shipping
- Label fileZPL, SBPL, PDF
- Print & apply
- Verifyscan
- Sortor reject
Where the label comes from
A scan or a weight and dimension reading triggers the WMS, WCS, or shipping software, which manifests the package and gets the carrier label through carrier APIs, then sends the label file to the printer.
Timing
The label must be ready before the package reaches the applicator. We size conveyor distance and tracking so data arrives in time at line speed.
Queue & match
Each package is tracked by ID and photo-eye position so the right label meets the right package, even with gaps and spacing changes.
No-label, wrong-label & late data
Missing, mismatched, or late labels are detected and handled, never applied as a guess.
Fail-safe defaults
Anything unverified goes to an exception lane by default.
Verification
Verification & quality
Presence & match
A scan after application confirms the label is there, readable, and matches the package it was meant for.
Print-quality grading
Verifiers grade barcodes to ISO/IEC 15416 (linear) and ISO/IEC 15415 (2D) when a grade is required, for example by retailer or GS1 compliance programs.
OCR & vision checks
Cameras read human-readable text, check placement, and confirm the right label type.
Reject confirmation
Sensors confirm rejected packages actually left the line.
Audit images
Images of applied labels stored for dispute resolution and traceability.
Standards
Standards & compliance
Labels we help produce are designed to meet these specifications for the scope of each project.

Define the SSCC in a GS1-128 barcode for logistic units, plus label layout, size, and placement.
Carrier label specifications
UPS, FedEx, USPS, and regional carriers each publish label formats and print-quality requirements that labels must meet to avoid surcharges or rejects.
Retail compliance
Big-box retailer routing guides require SSCC-18 labels that match the advance ship notice (ASN), with chargebacks for errors.
DSCSA serialization
Pharmaceutical cases and totes carry serialized identifiers and aggregation data. See healthcare & pharma distribution.
UDI for medical devices
FDA Unique Device Identification, with data in the GUDID database and barcodes issued under GS1 or HIBCC.
Food traceability
Lot and date codes, including traceability lot codes under the FDA Food Traceability Rule (FSMA 204).

Would you like to know more? Choosing an application method, print technology, and what barcode grades mean
Tamp vs wipe vs blow
Tamp handles varying package heights and positions well and gives firm adhesion, at moderate rates. Wipe-on is the fastest but needs consistent package position and a flat face. Blow methods avoid contact, protecting fragile or soft products, but place labels less precisely. Package type, speed, label size, and placement tolerance decide the choice.
Thermal transfer vs direct thermal
Thermal transfer uses a ribbon and produces labels that resist heat, abrasion, moisture, and time, which matters for cold chain and long storage. Direct thermal skips the ribbon, lowering cost and changeovers, and suits labels that only need to last through shipping.
What ISO grades A–F mean
ISO/IEC 15416 and 15415 grade barcodes on parameters such as contrast, decodability, and defects. Grades run from A (4.0, best) to F (fail); many compliance programs require a minimum such as C or better, so scanning "it reads" isn’t always enough when a grade is specified.
