UV Printing on Wood, Metal and Stone: How Flatbed UV Changed Editioning

A UV flatbed printer cures ink with ultraviolet light the instant it hits the substrate. Nothing soaks in, nothing migrates, and there is no decal or transfer film between the artwork and the surface. For artists used to giclée on paper, the change is dramatic: the substrate is now part of the work.

Substrates we print on

Anything flat (or near-flat) up to roughly 100 mm thick fits the bed. We routinely print on:

  • Hardwood and ply — grain telegraphs through the ink, intentionally
  • Aluminium, brass and stainless — with adhesion primer for outdoor work
  • Glass and mirror — with white ink layers for opacity control
  • Acrylic, Dibond, MDF, Valchromat
  • Slate, marble offcuts, terrazzo, concrete tiles

White ink is the trick

Almost every interesting UV job uses the white channel. White as a base layer makes colours pop on dark wood. White as a top layer (printed in reverse onto the back of glass) gives second-surface luminance. White spot-printed under selected areas creates day/night effects on transparent media.

We profile each substrate so the white density is matched to the colour pass — too thin and the colour goes muddy, too thick and the texture of the substrate is lost.

Why editioning artists love it

There is no negative, no plate, no screen. An edition of 25 panels is 25 prints — identical to within machine repeatability — and the artist signs the substrate, not a margin of paper. That changes how a piece sells and how it ages.
