Production Line Printers

What Information Can Be Printed on a Production Line?

The requirements for industrial product marking vary considerably. Depending on the product and industry, a wide range of different information may be required. Production Line Printers can apply, among other things, the following content:

• Product names and article numbers
• Batch and lot numbers
• Production and expiration dates
• Serial numbers
• Barcodes and 2D codes
• QR codes
• Logos and symbols
• Weight and quantity information
• Production and shift information
• Traceability information
• Variable data from databases or production systems

Direct printing offers particular advantages when variable information is required. The relevant print data can be automatically transferred to the marking system and updated during production. This makes it possible, for example, to mark different batches or serial numbers without manually replacing print templates.

Direct Printing Instead of Subsequent Marking

For many industrial applications, it makes sense to integrate product marking directly into the production line. The product can then be marked with the required information during manufacturing or packaging. An additional manual work step can therefore be eliminated.

With direct marking, the print information is applied directly to the surface of the respective product or material. Depending on the substrate and the required print quality, different printing technologies can be used.

The selection of the appropriate system depends, among other things, on the surface, production speed, required print image, position of the print head and environmental conditions.

Materials such as plastic, paper, cardboard, metal, wood or various composite materials can be printed. Porous and non-porous surfaces also place different requirements on ink, printing technology and print quality.

When selecting a system, the required print resolution should therefore not be the only consideration. What matters most is whether the printing technology can reliably operate with the respective material and production conditions over the long term.

Printing Barcodes and QR Codes Directly on the Production Line

Machine-readable codes are becoming increasingly important in modern production and logistics processes. Barcode Printers and systems for direct QR code printing can apply information for identification and traceability directly to products or packaging.

Barcodes can contain article numbers, batch information or other product-related data, for example. QR codes also provide the option of storing larger amounts of data in a relatively small area.

Sufficient print quality is essential for reliable automatic code reading. Edges must be clearly defined and the code must provide sufficient contrast. Production Line Printers must therefore deliver consistent print results even during continuous production.

Integration into Automated Production Processes

A modern Production Line Printer does not normally operate as a standalone system. It is integrated into the existing production process and can communicate with PLCs, conveyor belts, sensors or other machines, for example.

Print data can be transferred automatically via appropriate interfaces. This allows the system, for example, to identify which product is currently being manufactured and which marking needs to be applied.

When products or production orders change, the print template can be adjusted automatically. This reduces manual intervention and helps prevent marking errors during ongoing production.
