Special finish comparison
Foil Stamping vs Spot UV
Foil adds an opaque coloured, metallic or holographic material to selected artwork. Spot UV adds a clear gloss coating that reveals the print beneath it through sheen and tactile contrast. Choose foil when the added colour or metallic effect is essential; choose Spot UV when a clear highlight over printed artwork creates the intended contrast.
Compare how each finish creates emphasis
Both finishes use separate artwork layers and registration, but they produce different visual information.
| Decision factor | Foil stamping | Spot UV |
|---|---|---|
| Appearance | Opaque foil colour, metallic reflection or specialist effect. | Clear gloss that changes reflection over the base artwork. |
| Base colour | Can remain visible on dark or coloured stocks, subject to testing. | Depends on the printed colour beneath the clear coating. |
| Artwork | Solid vector shapes on a named foil separation. | Solid vector mask on a named varnish separation. |
| Detail and registration | Fine gaps and alignment need production tolerances. | Very fine detail and tight alignment also require practical tolerance. |
| Proofing | Screen proof cannot show foil colour or reflection. | Screen proof cannot show gloss level or tactile contrast. |
Select the effect before preparing the layer
Use foil for a logo, border or short detail that needs to remain opaque or materially distinct from process print. Use Spot UV to reveal a pattern, logo or selected printed area through reflected light. If the design needs a new metallic colour, clear varnish cannot replace foil; if it needs only surface contrast, foil may add unnecessary colour and tooling.
Simplify artwork for reliable production
Avoid gradients, transparency and photographic texture on the special-finish mask unless a specific production method has been agreed. Keep fine lines, gaps and type within confirmed limits. Allow sensible clearance from trim, holes, folds and perforations, and do not assume the finish can register perfectly to hairline printed detail.
Approve a physical reference when appearance matters
Foil shades change with material, lighting and viewing angle. Spot UV visibility depends on the background colour and sheen. A PDF proof confirms position, not the material effect. Compare a representative sample when the finish is central to brand colour or tactile presentation and record the selected foil or varnish direction in the job specification.
Prepare the chosen finish
- Intended visual effect
- Separate named vector layer
- Minimum line and gap checks
- Registration allowance
- Base surface compatibility
- Representative physical sample
