Glass Inner Code Printing serves as an innovative alternative solution to conventional adhesive labels for glass traceability management. In industries such as photovoltaic glass and electronic glass, traditional paper labels are prone to problems such as falling off and aging in high temperature, high humidity, and ultraviolet environments, affecting the traceability of the product life cycle. At the same time, the continuous procurement and manual labeling process of label paper, adhesive backing, ribbon and other consumables also bring high operating costs.
LIONTEC In-glass code printing technology provides a highly reliable alternative. This technology uses an industrial-grade glass inkjet system to directly print high-precision QR codes or barcodes on the inner surface of the glass, integrating the identification information with the glass substrate. This inkjet method of replacing labels physically avoids the risk of labels falling off.

Conclusion: Reliability test results of the inner surface of glass using inkjet coding process Pass.
Based on the photovoltaic inkjet printing process and using nano-scale UV curing ink, the barcode formed on the inner surface of the glass has excellent weather resistance. After two kinds of DH2000 (double 85 high temperature and high humidity) and UV500 (ultraviolet aging) After rigorous testing, the readability rate of glass barcode printing can reach over 99.95%. This means that the identification information will continue to be reliable throughout the product’s life cycle of more than 25 years.
Reduce consumable costs by more than 90%
Since consumables such as label paper, adhesive backing, and ribbons are no longer used, comprehensive material and management costs can be reduced by more than 90%. At the same time, fully automatic online inkjet printer printing replaces manual labeling (usually the efficiency is not higher than 200 pieces/small time), significantly improving the level of production line automation.
Streamlined process and environmentally friendly
Non-contact printing avoids physical damage to the glass surface. The UV ink used is an environmentally friendly material that is solvent-free and VOC-free, in line with the trend of green manufacturing.
Reliability test conclusion: The DH2000 and UV500 test results are both OK, indicating that the photovoltaic glass internal code inkjet printing process has high stability on the inner surface of the glass and can be used as an effective alternative to traditional labels and is suitable for
Photovoltaic glass, electronic glass, home appliance glass and other fields that require high-level traceability.
LIONTEC’s mature Glass Inner Code Printing technology adopts industrial UV inkjet system to print permanent QR codes and barcodes directly inside glass substrates. Different from surface printing that suffers from scratching and fading risks, the inner embedded marking structure stays intact under long-term weathering aging tests, reaching a barcode reading rate higher than 99.95%. We have completed strict reliability verification including DH2000 double 85 high temperature & humidity test and UV500 ultraviolet aging test, proving stable identification performance for more than 25 years full product lifecycle. Matching automatic visual inspection equipment, the whole line can automatically screen out unreadable, offset or missing codes, realizing fully automatic online marking production. By replacing label-related consumables and manual sticking procedures, Glass Inner Code Printing cuts overall material and labor expenditure by more than 90%. Meanwhile, non-contact inkjet processing avoids scratching damage to glass surfaces, and solvent-free VOC-free UV ink meets green manufacturing standards, making it widely applied in photovoltaic module glass, electronic display glass, home appliance glass and other traceability-scenarios with strict environmental and durability requirements.
