When your delivery dates and read-rates are on the line, line speed—not lab speed—decides whether you hit plan. HeatSign’s online (flying) fiber and CO₂ laser coders help you keep pace with your conveyor, print durable, scannable codes, and stabilize OEE—without inks, nozzles, or solvent headaches.
Quick wins you can expect
- Higher throughput with encoder/PLC-synchronized marking
- No consumables → lower TCO, cleaner workplace
- Audit-ready print quality (dates, batches, QR/GS1, UDI)
- Rapid integration with your existing conveyor, sensors, and HMI
Why “high-speed” matters to your OEE (and TCO)
You want fewer stoppages, faster changeovers, and codes that pass inspection. Laser coding removes inks and makes-ready delays while keeping your conveyor moving.
- Throughput: mark at the conveyor’s actual pace with encoder sync
- Changeovers in seconds: digital recipe switch; no ink purge
- Lower lifetime cost: no inks/solvents, less cleanup, fewer spare heads
- Quality & compliance: repeatable contrast; supports QR/GS1/UDI standards
When dealing with beverage bottling or cosmetic packaging, the closures themselves present a unique challenge due to their small size and immense throughput requirements. Replacing messy inkjet coders with our specialized high-speed laser cap marking solutions ensures you get smudge-free, permanent traceability on PE, PET, or aluminum caps at full production speeds, drastically lowering your cost-per-mark and stabilizing your OEE.
Your two high-speed options
1) CO₂ Laser Coding — Packaging Specialists
Best for paperboard, coated cartons, labels, wood corks, and some films (via ablation/foaming depending on substrate).
- Scanner speed: up to ≤9,000 mm/s (F-θ dependent)
- Typical line speed: 80–250 m/min for date/batch codes (code size & substrate dependent)
- Why you’ll like it: high-contrast date/batch codes without ink, with clean edges and stable read-rates
- Recommended models:
- CO₂ Laser Coder for Packaging Lines (30–60 W)

2) Fiber Laser Coding — Metals & Engineering Plastics
Best for stainless steel, aluminum, anodized aluminum, titanium, and many engineering plastics.
- Scanner speed: up to ≤12,000 mm/s (F-θ dependent)
- Typical line speed: 60–200 m/min for UDI/QR/alphanumeric (module size & surface dependent)
- Why you’ll like it: permanent, abrasion-resistant marks that stay readable in machining, washing, and logistics

Typical Line Speeds & Parameters (Examples)
Use this as a template; swap in your verified values. Always list lens, code size, fill/line spacing, frequency.
Material / Application | Code Type & Size | Lens (F-θ) | Power / Freq. | Scanner Speed (mm/s) | Line Speed (m/min) | Result |
|---|---|---|---|---|---|---|
PET bottle label | Date code 6×18 mm | F=300 | [xx W / xx kHz] | [≤9,000] | [180] | Clear ablation |
Paperboard carton | Lot code 8×22 mm | F=300 | [xx / xx] | [≤9,000] | [220] | High contrast |
Stainless (SUS304) | UDI 10×10 mm QR | F=160 | [xx / xx] | [≤12,000] | [120] | Dark, readable |
Anodized Al. | Text 8×25 mm | F=254 | [xx / xx] | [≤12,000] | [160] | White mark |
TPU (with absorber) | Batch code 6×20 mm | F=254 | [xx / xx] | [≤12,000] | [100] | High contrast |
Case studies you can audit
Food & Beverage — Mineral water bottling
You moved from inkjet to CO₂ laser on PET labels. With a line speed around 180–220 m/min and 6–18 mm codes, you eliminated ink stoppages and stabilized read-rates at the packer. Recipe changeovers < 60s.
Wire & Cable — Sheath coding
Fiber laser prints alphanumeric and meter marks at line speed ~120–160 m/min using F=254 optics. Marks remain legible after abrasion/solvent tests. Inline verify ties to a visible alarm.
Automotive — UDI on stainless
On SUS304, a 10×10 mm UDI prints at ~120 m/min with F=160. A vision system grades the QR, logs pass/fail, and integrates with your PLC for reject handling.

FAQs
The guide mentions 'encoder sync.' What is this and why is it important for high-speed marking?
An encoder is a device that measures the actual speed of your conveyor belt. Encoder synchronization is important because it allows the laser coder to perfectly match its marking speed to the conveyor’s pace, ensuring that the code is printed accurately and consistently on every item, even as line speeds fluctuate.
What is the key advantage of a high-speed laser coder over an traditional inkjet system?
The key advantage is the elimination of consumables and their associated problems. The guide highlights that by using a laser, you can ditch inks, nozzles, and solvents, which not only lowers your Total Cost of Ownership (TCO) but also provides a cleaner workplace.
The guide lists two high-speed options. Which one is best for marking a date code on a paperboard carton?
For marking on materials like paperboard, coated cartons, and labels, the guide recommends a CO2 Laser Coder. It is described as the “packaging specialist” and is ideal for creating high-contrast date and batch codes on these types of organic materials.
How does a high-speed laser system help a business meet compliance standards like FDA UDI?
A high-speed laser system helps with compliance by creating permanent, high-quality, and repeatable marks. It supports the printing of the specific codes required by these standards, such as QR codes, GS1 DataMatrix, and UDI, and can be integrated with a vision system to verify and log each mark for audit-ready records.
The text mentions a case study in the food and beverage industry. What was the main benefit of switching to a CO2 laser?
In the food and beverage case study, a mineral water bottling company switched from inkjet to a CO2 laser for marking PET labels. The main benefit was that they eliminated the production stoppages that were being caused by ink-related issues, which stabilized their code read-rates at the final packing station.
If I need to mark on both metal parts and plastic packaging, is there one laser that can do both?
No, you would typically need two different laser types for those materials. The quick decision guide recommends a Fiber laser for metals and engineering plastics, and a CO2 laser for packaging, labels, and films. For mixed materials, it is suggested to test both and optimize for your specific needs.
What does the term 'scanner speed' refer to, and how fast can it be for a fiber laser?
The ‘scanner speed’ refers to the maximum theoretical speed at which the laser’s internal galvo mirrors can move. The guide notes that for a fiber laser, this can be up to 12,000 millimeters per second, which is what allows it to keep up with fast-moving production lines.
What kind of 'out-of-the-box' safety features are typically included with these high-speed systems?
The guide lists several standard safety features. These include Class-1 enclosures to contain the laser, safety interlocks that shut the laser off if a door is opened, fume extraction systems, and light curtains.
