【Client Background】
An industrial manufacturing enterprise provides barcode labels and serial number labels for its product series. There are many product categories, each model requires independent barcode information, serial number coding and QR code, which are used for production line scanning and after-sales tracing after equipment application.
💬 Customer Needs
The client's original labels used pre-printing method - each model was separately plate-made and printed in batches, requiring re-plate-making when changing models with fixed plate costs. As product models expanded from a few to dozens, plate costs and plate-making cycles continued to accumulate. More challenging was that demand varied greatly across models: some models required thousands of pieces at once, while others only needed dozens, making traditional printing unable to adapt to such flexible demand.
The client hoped to find a way to flexibly switch barcode content for different models without changing plates, while ensuring barcode recognition rate and printing clarity.
Core demands: Multi-model variable data + Barcode recognition rate + Small batch flexible production.
Project challenges:
✓ Multiple models require different barcodes and serial numbers, traditional plate-making cannot flexibly switch
✓ Barcode size is small, requiring high printing precision and recognition rate
✓ Labels need to be pasted on equipment outer surfaces, requiring certain adhesive strength and wear resistance
✓ Quantity varies greatly across models, some only need dozens of pieces
💡 Solution
Lexiang adopted a digital printing + variable data technology solution, batch outputting labels with different codes on one printing plate. The barcode, serial number and QR code content of each label are independently generated in electronic files. Changing models only requires replacing data files, with zero plate costs and zero waiting. Labels use matte white self-adhesive (80μ) with matte lamination (25μ), ensuring barcode clarity, wear resistance and adhesion meet industrial use environment requirements.
Selection analysis:
Why choose digital printing + variable data instead of traditional plate-making printing?
Traditional plate-making printing requires re-plate-making for each model change (plate costs range from 500-2000 yuan), with costs becoming uncontrollable as models increase. Under digital printing mode, one electronic file can contain dozens of labels with different codes, with one-time fee input and freely changeable content, showing obvious cost advantages in multi-model scenarios.
Why not use thermal transfer or post-processing inkjet?
Thermal transfer and inkjet are suitable for on-demand printing scenarios, but each label needs to be printed one by one, resulting in low efficiency for large batches. Digital printing completes batch output in one pass, with efficiency far higher than single-sheet printing. Also, digital printing resolution (1200dpi+) is higher than most thermal transfer printers, with sharper barcode edges and higher recognition rates.
Why choose matte white self-adhesive (80μ)?
Industrial label application surfaces are mostly metal or engineering plastics. Matte surface does not reflect light, ensuring stable reading by barcode scanners. 80μ thickness provides good flexibility when applying to curved surfaces without edge lifting.
Why lamination?
Labels on equipment surfaces may come into contact with oil, cleaning wipes or slight scratches during use. Lamination (matte film 25μ) provides a wear-resistant protective layer, extending label service life.
Production implementation and quality control:
① Receive each model's coding rules (Excel/CSV) → ② Variable data layout (barcode + serial number + QR code)
③ Digital printing → ④ Matte lamination (25μ)
⑤ Die cutting and waste removal → ⑥ Slitting and rewinding
⑦ Scan verification (single or sample barcode grade inspection) → ⑧ Pack and ship by model
Core quality control: Barcode grade must reach ISO/IEC 15416 standard Grade C or above (commonly used standard for production line scanning). Each batch is sampled and verified using barcode detector.

Case Summary:
Barcode labels for multi-model industrial products face management challenges of many models, small quantities per model, and different codes. This case adopts digital printing + variable data solution, independently outputting barcodes, serial numbers and QR codes of different models within the same batch. Changing models only requires updating data files, without separate plate-making for each model. Labels use matte white self-adhesive (80μ) with matte lamination (25μ), ensuring firm adhesion on metal and engineering plastic surfaces and wear resistance in daily use.
Lexiang Experience:
Applicable scenarios: Multi-model industrial labels, variable data labels, small batch label requirements
Material recommendations: Choose matte self-adhesive (80μ) for indoor equipment; choose PVC (80μ) or enhanced lamination for oily environments; choose PET (50μ) + weather-resistant lamination for outdoor equipment
Not applicable scenarios: Not suitable for surfaces requiring strong solvent (acetone, benzene) resistance; not suitable for direct food contact label scenarios (requires food-grade label materials)
Notes: Barcode grade is related to printing resolution and material surface smoothness. Matte materials have slightly lower barcode contrast than glossy materials. Sample verification of barcode readability is recommended before mass production

Barcode Label Material Selection Guide
Matte self-adhesive (80μ): Most commonly used, adapts to most indoor industrial scenarios. Non-reflective, stable scanning. High cost-performance.
PVC label (80μ): Oil-resistant, water-resistant, weak acid/alkali resistant. Suitable for equipment maintenance and industrial field environments.
PET label (50μ): High temperature resistant (-40°C to 150°C), strong chemical solvent resistant. Suitable for outdoor equipment and temperature-resistant scenarios.
Thermal label: No toner consumption, suitable for on-demand printing. But thermal layer is not resistant to high temperature and UV, not suitable for long-term storage.
Variable data printing vs pre-printing vs thermal transfer
Variable data printing (digital): Suitable for multi-model, small batch, zero plate cost, flexible content.
Pre-printing (traditional offset): Suitable for large batches of single model, lowest unit cost, but long plate-making cycle.
Thermal transfer (single-sheet printing): Suitable for on-demand printing, strong instantaneity, but low efficiency, suitable for dozens of pieces per day.
