QR Code Laser Marking Guide: Readability, Size, and Application Standards
QR code laser marking is a modern traceability method that enables products to be integrated with digital data. QR (Quick Response) codes are widely used in manufacturing, logistics, and retail sectors thanks to their high data capacity and fast readability advantages. With fiber, CO₂, and UV laser systems, QR codes can be marked on metal, plastic, glass, and organic surfaces. This guide explains in detail QR code marking techniques, readability criteria, and industrial applications.
QR Code Marking and Technical Features
What is a QR code?
A QR code is a barcode system that carries two-dimensional data.
Data capacity
Data such as text, URL, and serial number can be stored within a QR code.
Code size
The physical size of the code affects readability.
Module (pixel) structure
A QR code consists of square modules.
Error correction level
QR codes have an error correction algorithm.
Laser marking method
The QR code is created through surface contrast.
Contrast and readability
High contrast is critical for camera readability.
Marking precision
Small QR codes require high precision.
Effect of surface type
Metal, plastic, and glass produce different results.
Industrial application areas
- Product tracking
- Logistics processes
- Retail
- Digital integration
