Barcodes and QR codes connect physical products to digital information.

They are widely used for:

• Product identification

• Inventory management

• Manufacturing traceability

• Logistics

• Anti-counterfeiting

• Digital marketing

Printing these codes reliably requires both resolution and stable ink control.

High-Resolution Code Printing

PIJ systems provide adjustable printing resolution.

This allows manufacturers to optimize the print quality required for machine-readable codes.

Clear code modules and edges are particularly important for QR-code scanning.

Variable QR Codes

The system can print unique 2D codes continuously.

This means every package or component can receive a different code.

Such codes can link to:

• Product databases

• Traceability records

• Authentication platforms

• Customer information

• Digital content

Variable Barcodes

The same technology can print changing one-dimensional barcodes.

This can support logistics, production scheduling and inventory control.

Printing Additional Information

Barcodes and QR codes can be combined with:

• Text

• Serial numbers

• Product names

• Graphics

• Running numbers

All of these elements can be printed within one layout.

Applicable Materials

Code printing can be considered for suitable:

• Cartons

• Paper

• Plastic

• Film

• Labels

• Metal

• Pipes

• Building materials

The actual substrate should be tested for contrast, curing and code readability.

Conclusion

Piezo inkjet technology provides an effective platform for industrial QR-code and barcode printing.

Its high-resolution and variable-data capabilities allow manufacturers to create unique machine-readable identification while products continue moving through production.
