Comparison of Stamping and Laser Marking
Comparison details | Laser marker | Stamping |
---|---|---|
No missing or faint characters | Very good | Poor |
No need to perform product tooling changes | Very good | Very poor |
Marking does not fade | Very good | Very poor |
Ability to perform automatic marking for calendars and counters | Very good | Very poor |
Support for high-speed lines | Good | Poor |
Ability to perform clear marking on curved surfaces, rough surfaces, and soft parts | Very good | Acceptable |
Ability to perform clear marking of small characters | Very good | Acceptable |
Laser Marking vs. Ink Stamping on Wrapping Film
Ink systems are often used to mark individual wrapping films, but are unable to create permanent marks since they simply place ink on the outer surface of the film. There's also a risk that substances such as salad dressings, oils and alcohol contact the ink.
Individual wrapping film benefits from laser marking because the material itself is discolored and processed so the marking doesn't fade.
Application Examples


Key Laser Marking Advantages
- 1Quality
- Accurate marking that does not fade due to contact with oil or alcohol is possible.
- 2Cost
- The running costs of ink ribbons and maintenance components, which increase according to the number of sheets used, are eliminated.
- 3Work efficiency
- Tooling changes for different models and ink ribbon replacements are not necessary, which greatly reduces the amount of required work.
- 4Environment
- The elimination of garbage such as ink ribbons contributes to environmental initiatives (CSR).
Laser Marking vs. Stamping on Cartons
Laser markers are used to directly mark cartons. This improves the product image, since high-quality marking with no faint or missing characters is possible.
Laser markers also help improve line stability when visual marking confirmation is required, since their marks are less susceptible to environmental degradation.

Application Examples


Key Laser Marking Advantages
- 1Quality
- Stable marking without defects (like missing or faint characters) is possible, even on rough surfaces.
- 2Cost
- The running costs of ink ribbons and maintenance components, which increase according to the number of sheets used, are eliminated.
- 3Work efficiency
- There's no need to stop production while marking; products can be marked while being conveyed. Overall productivity also improves since the marking contents can be changed with the touch of a button.
- 4Environment
- The elimination of garbage such as ink ribbons contributes to environmental initiatives (CSR).
Laser Marking vs. Roller Stamping on Cables
Direct marking can be performed on cables moving at high-speeds. Laser markers accurately create a colored surface that doesn't fade, so stable marking is possible even on small wire diameters and rough surfaces.

Application Examples


Key Laser Marking Advantages
- 1Quality
- Stable, defect-free marking is possible on high-speed lines. Accurate marking is possible on small wire diameters and rough surfaces.
- 2Cost
- Detailed, damage-free traceability is possible with laser markers. There are also zero running costs.
- 3Work efficiency
- There is no need to refill the ink every few hours and the work required to change the marking details is greatly reduced.
- 4Environment
- No ink means no organic solvents, which contributes to environmental health and safety.
Laser Marking vs. Inkjet Printing on Bottles
Laser markers work on both transparent and colored bottles. They're even capable of handling multiple bottle types on a single line, since KEYENCE's 3-Axis control eliminates the need for tooling changes.
No ink also means no running costs and no need for ongoing maintenance.

Application Examples


Key Laser Marking Advantages
- 1Quality
- 3-Axis control enables stable, beautiful marking on multiple bottle shapes.
- 2Cost
- Detailed, damage-free traceability is possible with laser markers. There are also zero running costs.
- 3Work efficiency
- Eliminates the need for tooling changes and regular maintenance.
- 4Environment
- Because no ink is used, no organic solvents are used as well, which contributes to environmental initiatives (CSR).
