Tempered Glass Definition
Printed glass features digitally or screen-printed patterns, logos, or images fused onto the surface using ceramic inks that are fired during the tempering process. It offers durability, color stability, and design flexibility.

Customizable full-color printing
UV and scratch resistant
Long-lasting designs
Combined with tempered or laminated glass
Applications
Decorative building facades
Interior wall cladding and partitions
Elevator interiors
Door panels, wardrobes, and kitchen glass
Signage and branding elements
Subtypes
Digital printed glass (photo-quality patterns)
Tempered printed glass
Laminated printed glass
Insulated printed glass
Frosted or etching-style printed glass
Category | Parameter | Standard Example | Technical Notes |

|
Max. Size | 3300×13000 mm |
| Minimum Hole/Notch Margin | Edge distance ≥2×glass thickness (e.g., 5mm glass → ≥10mm) | Prevents edge stress concentration |
Heating Stage | Furnace Temperature (°C) | 700~720 (near softening point) | Heating time: 40~60 sec/mm (≤6mm), 60~80 sec/mm (≥8mm) |
