In automotive glass applications, ink printing acts as an unsung "magician," subtly playing a crucial role in enhancing the vehicle’s aesthetic and safety. The black border on the glass, drawn with ink, not only conceals the sealant and internal components but also elevates the car’s appearance. More importantly, it blocks ultraviolet (UV) rays, delays adhesive aging, and strengthens the bond between the glass and the vehicle body.
Silk Screen Printing: The Cornerstone of Automotive Glass Ink Technology
Silk screen printing, a mainstream process in automotive glass manufacturing, is favored for its high adaptability and low cost. Whether for intricate scale markings or large areas of black borders, it is easily achievable. Additionally, its compatibility with various ink types and relatively low cost make it an industry standard. However, its lack of flexibility in plate-making and room for improvement in production efficiency present significant challenges in large-scale manufacturing.
The production of automotive glass relies heavily on professional silk screen printing techniques, and the continuous optimization of silk screen printing equipment is injecting more possibilities into glass manufacturing. Jetta's fully automated glass screen printer is a key player in this field. Currently, nearly all of the world’s top 10 automotive glass manufacturers are using JUIST’s equipment.
In response, JUIST’s fully automated screen printers enhance production efficiency and precision through innovative design and intelligent control, solving the challenges of mass production while maintaining high consistency in the process.
With the rise of new energy vehicles and intelligent driving, the ink technology on automotive glass is rapidly evolving. Let’s explore the unique "magic" that ink brings to automotive glass.

Current Applications: Comprehensive Ink Printing Coverage
1. Comprehensive Scene Coverage
- Front Windshield: The ink-drawn black border not only hides internal structures but also blocks UV rays, improving cabin comfort. The markings on the glass, such as “AS1” and “AS2,” are also ink printed, providing guidance for compliant vehicle use.
- Side Window Glass: The ink on the edges enhances the glass’s bonding strength, concealing internal structures and improving the overall aesthetic integration.
- Rear Windshield: Brand logos, defrosting wire markings, and other features are realized through ink printing, combining functionality and beauty.
2. Process and Technology Analysis
- Silk Screen Printing: As the mainstream process, silk screen printing is popular for its high adaptability and low cost, though its flexibility in plate-making is limited, and its efficiency needs improvement.
- Digital Printing: No plate-making is required, allowing for highly flexible pattern printing, suitable for small-batch customizations. However, the cost of equipment and consumables is high, and it currently serves as a supplement to silk screen printing.
3. Market Landscape
- Ink Suppliers: Global leading ink brands, such as PPG and AkzoNobel, dominate the market with their advanced technology and stable product performance, especially in the high-end automotive glass sector, where technological barriers are high. As domestic ink companies continue to enhance their technology, some competitive brands are gradually emerging by offering high cost-performance and rapid market response.
- Glass Manufacturers: Domestic and international brands, such as Fuyao Glass, are injecting vitality into the automotive glass market with their exquisite craftsmanship and technological innovations.
Future Trends: Merging Technology and Sustainability
The widespread adoption of intelligent vehicles not only brings new challenges but also opens up fresh opportunities for ink printing technology. For example, the application of transparent conductive ink is gradually replacing traditional heating wires, enhancing vehicle smart dimming and defrosting functions while further driving innovation in automotive glass technology. At the same time, the demand for conductive ink printing in silk screen printing for autonomous driving and vehicle sensor integration continues to grow, upgrading the functionality of automotive glass. JUIST’s silk screen printing equipment has been deeply adapted to the characteristics of eco-friendly inks, ensuring that both production efficiency and environmental standards are met, providing strong support for the implementation of these innovative technologies.
