UV Printing by Substrate Material

Substrate Reference

Eight substrate categories, different setup profiles

Figures and notes below are general substrate behavior references, not a guarantee for every ink formulation — confirmed against your specific substrate during RFQ.

Acrylic (PMMA)

The most common rigid substrate for UV flatbed work — smooth, non-porous, good ink adhesion without pre-treatment in most cases.

Clear and cast acrylic generally hold adhesion better than extruded sheet
White ink underprint needed for color accuracy on clear or tinted acrylic
Static buildup can attract dust during printing — ionizing bars are a common factory mitigation

PVC Foam Board (Sintra/Foamex-type)

Lightweight rigid board widely used for signage — porous surface takes ink well but is heat-sensitive.

Low melting point limits LED-UV lamp power/pass speed to avoid substrate warping
Good ink adhesion without primer in most cases
Common thicknesses run 3mm-10mm depending on application

Glass

Non-porous and chemically resistant — the hardest common substrate for long-term adhesion without surface prep.

Primer or surface treatment is typically required for scratch/dishwasher-resistant results
White ink underprint standard for opacity on clear glass
Curved or tempered glass may need rotary attachment or custom jig

Wood & MDF

Porous and often textured — grain pattern and sealing level change how sharp the print comes out.

Raw wood should be sealed before printing to prevent ink bleed into grain
Varnish layer commonly applied for scratch resistance and gloss/matte finish control
Natural grain variation means color consistency is checked per batch, not assumed uniform

Coated Metal & Aluminum Composite

Pre-coated or anodized metal panels — adhesion depends heavily on the coating, not the base metal.

Powder-coated or anodized surfaces generally print well without primer
Raw/untreated metal typically needs a bonding primer
Common in signage, nameplates and control panel overlays

Leather & Fabric

Flexible, often textured substrates — requires lower curing power and careful vacuum table hold-down.

Flexible substrates need secure flat-bed hold-down (vacuum or tape) to avoid print misregistration
Softer curing profile reduces the risk of a brittle, cracking ink layer on flex points
Common for promotional items, labels and personalized goods

Ceramic & Tile

Dense, non-porous, heat-stable — good dimensional stability but needs adhesion-focused ink/primer matching.

Glazed ceramic behaves similarly to glass for adhesion purposes
Unglazed/porous ceramic takes ink more readily but with less gloss control
Common for decorative tile, coasters and architectural panels

Rubber & Soft-Touch Substrates (Mousepads)

Soft, flexible, low-energy surfaces — among the more demanding substrates for long-term adhesion.

Surface energy is often too low for standard UV ink without a bonding layer
Flex and abrasion resistance should be specified and tested, not assumed from a datasheet
Common for mousepads, phone grips and soft promotional items
