Smudging is usually a practical line issue involving ink, substrate, handling time, print distance or product movement.
Help with inkjet codes that smudge, blur or rub off on bottles, cartons, films, labels and packaging lines.
The right recommendation depends on the material, print area, expected contrast, dry time, production speed and how operators will change messages. Lancing can look at your sample pack and advise whether CIJ, TIJ, large character or handheld inkjet is the best fit.
Date, batch, lot, expiry, serial number, barcode, QR code or simple product identification.
Plastic, glass, metal, carton, label, sleeve, pouch, tray, sack, case or coated packaging.
Speed, printhead position, product sensor, encoder, brackets, guards and operator access.
Send the pack type, code example, line speed and available space. We can suggest the best coding route before you commit to a machine.
These pages are written around real packaging problems: substrate, line speed, print position, operator changeover and traceability content.
Check the sample pack, print location, character size and message format before choosing a machine.
Plan brackets, sensor position, encoder use, guarding and operator access around the actual line.
Confirm code legibility, dry time, message control and routine cleaning so the line can run with confidence.
Compare machine types and related print requirements before requesting a recommendation.
Yes. The usual print content is a date, batch number, lot code, expiry date, barcode, QR code or production reference. The best technology depends on the pack surface and line speed.
Ink choice and print position matter. A sample pack check helps confirm contrast, adhesion and dry time before installation.
Most installations can be designed around an existing conveyor or machine using brackets, sensors, encoders and practical guarding access.
Share your product, code content, line speed and pack material for practical UK advice.
| Symptom | Likely areas to check first |
|---|---|
| Code smears immediately | Dry time, ink deposit, temperature, airflow and contact with a guide, belt, sleeve or operator. |
| Code wipes off after drying | Ink chemistry, contamination, coating, surface treatment and downstream abrasion. |
| Code looks stretched or blurred | Encoder slip, speed setting, product bounce, throw distance and printhead alignment. |
| Only some packs fail | Supplier variation, condensation, filling temperature, product orientation and intermittent contact. |
| Text reads but barcode fails | Module size, quiet zone, contrast, edge definition, distortion and verifier requirement. |
Change one variable at a time and keep an accepted sample, settings and pack reference. Cleaning or increasing ink density without identifying the cause can hide the problem temporarily and increase consumption.
