This video demonstrates SJH UV mirror silver ink: a high-gloss mirror silver finish after UV curing with excellent adhesion - for packaging, labels and decorative printing.
The video shows the surface of UV mirror silver ink after curing, with a high-reflectance mirror quality close to electroplating and metal foil. The key lies in the flatness of the ink surface and pigment alignment: the flatter the surface, the stronger the specular reflection and the closer it reads to metal, so control of printing pressure, ink volume and curing conditions matters a great deal.
Observed from different angles, the mirror silver shows a pronounced angle-dependent reflection. This high reflectance is why mirror silver can partly replace hot stamping and metallised transfer: with the same metallic look, the ink route has a shorter process chain, can print local patterns and overprints easily with conventional inks, offering clear design flexibility.
The video shows the adhesion of the film. Mirror silver is a high-pigment system, and adhesion to non-absorbent substrates (PET, metallised paper, laminated surfaces) is the property that most needs validation - insufficient adhesion causes flaking during die cutting, folding and abrasion. Before volume production, proof on the actual substrate and through the actual downstream process.
| Effect | High-reflectance mirror finish after UV curing, close to plating and metal foil |
|---|---|
| Replacement value | Can partly replace hot stamping and metallising: shorter process, local printing, overprintable |
| Key specs | Surface flatness (defines the mirror) and adhesion to non-absorbent substrates |
| Typical use | Packaging, labels, decorative printing, premium gift boxes, cosmetics packaging |
The core competitiveness of UV mirror silver is replacing hot stamping with printing - bringing a metallic effect into the normal printing flow, ideal where local metallic areas are wanted without the cost and constraints of a separate stamping step. Two things must be confirmed when specifying: substrate type (non-absorbent stocks need a dedicated formula) and downstream process (die cutting and folding test adhesion). Verify both by proofing on the actual substrate.
