Application
Decorative and printed PVB in architecture
Printed PVB carries full-colour artwork on the interlayer, sealed inside a safety laminate. It offers photographic colour range that ceramic frit cannot match, and durability that applied surface film cannot match — while retaining post-breakage fragment retention, so it can be used in balustrades and overhead glazing.

Printed interlayer vs the alternatives
| Method | Colour range | Durability | Safety glazing | Best for |
|---|---|---|---|---|
| Printed PVB interlayer | Full photographic colour | Sealed inside the laminate | Yes — full retention | Feature glazing, artwork, gradients, branded glass |
| Ceramic frit | Limited palette, fired colours | Extremely durable, fired to glass | Depends on build-up | Solar shading patterns, dots and lines, external use |
| Applied surface film | Full colour | Exposed — scratches, lifts, weathers | No contribution | Temporary graphics, retrofit |
| Sandblast / acid etch | None — surface effect only | Durable but marks easily | No contribution | Simple privacy patterns |
The advantage that decides most projects
Printed interlayer produces decorative glass that is also safety glass. Because the artwork sits inside a PVB laminate, the finished panel retains post-breakage fragment retention — so it can be specified for balustrades, overhead glazing, partitions subject to impact requirements, and anywhere else the standard demands a safety laminate.
Decorated glass produced by surface methods does not carry that. In practice this frequently settles the specification before colour range or cost enter the discussion.
What a printed laminate specification needs
- Artwork at final size with bleed, in vector or high-resolution raster.
- The exact glass build-up the print will be laminated into — it changes how colour reads.
- Opacity intent: translucent for light transmission, opaque where the panel must block sight lines.
- A laminated proof of the actual build-up, approved before production.
- Panel layout and orientation where artwork runs across multiple panels.
- Edge treatment, since printed artwork meeting a polished edge shows any registration error.
Frequently asked questions
Can printed interlayer be used externally?
Yes — the print is sealed inside the laminate and protected from weather and UV by the outer glass ply. For fully exposed edge conditions, confirm edge sealing details, since edge moisture ingress affects printed laminates the same way it affects clear ones.
How does printed interlayer compare on cost to ceramic frit?
For simple repeating patterns in one or two colours, frit is usually cheaper. For photographic imagery, gradients or multi-colour artwork, printed interlayer is generally more economical — and it does not require a separate firing step in the glass line.
Is there a minimum order for printed interlayer?
Yes, and it varies with artwork complexity and panel size. Because each project is effectively a bespoke print run, minimum quantities are higher than for clear or standard coloured film.
