What are the Differences Between Inkjet and Laser Marking?
Today, inkjet and laser marking technologies are widely used to keep track of products and to add serial numbers and expiration dates. However, the advantages, disadvantages and usage areas of both technologies differ. So, what are the differences between inkjet and laser marking? Which one is more suitable for your needs?
1. Technology and Working Principle
Inkjet Marking
Inkjet marking works on the principle of spraying micro droplets from the print head onto the surface. The inks used are usually solvent-based, water-based or UV-drying. This allows printing on a variety of materials such as plastic, metal, glass, paper and wood.
Laser Marking
Laser marking occurs when laser beams are concentrated on the surface and leave a permanent mark on the material. This process occurs by burning, melting or vaporizing the layer on the material.
2. Persistence and Durability
- Inkjet Marking: Since it is made with ink, it can be erased over time when exposed to external factors such as water, chemicals and abrasion.
- Laser Marking: It is indelible, resistant to water, chemicals and scratches as it is engraved on the surface of the material.
3. Speed and Efficiency
- Inkjet Marking: Can print quickly but requires drying time, which can slow down workflow in some cases.
- Laser Marking: It can print instantly and does not need a drying process.
4. Cost
- Inkjet Marking: Initial costs are low, but inks and maintenance costs can increase over time.
- Laser Marking: Has a high initial cost but can be more economical in the long run as it uses no consumables.
5. Areas of Use
- Inkjet Marking: Ideal for food packaging, plastic bottles, paper products, cardboard boxes and serial numbers.
- Laser Marking: It is used in applications requiring permanent marking on hard surfaces such as metal, glass, wood and plastic.
6. Environmental Impact
- Inkjet Marking: Inks can contain chemicals and solvent-based ones can be harmful to the environment.
- Laser Marking: Environmentally friendly as it uses no chemicals or consumables.
Conclusion
Inkjet marking can be a good option if you need to write low-cost, variable information quickly. However, if you want a long-lasting, durable and permanent marking, laser marking is more advantageous. When making your choice, it would be best to decide according to your needs and area of use.
