Digital Masking for Metal Finishing
Print precise masks directly on aluminium.
Grind, brush, or blast - then remove cleanly.
See how it works →SIGNRACER Digital Masking is a production-ready masking process that prints high-resolution patterns with UV-curable masking fluid. It replaces manual tape, cut stencils, and time-intensive masking steps with a repeatable digital workflow so you can create crisp logos, fine lines, and selective protected zones on metal parts with confidence.
Used by Leading Industries
Why Manufacturers Switch to Digital Masking
Faster Throughput, Less Manual Work
- Reduce time spent cutting, applying, aligning, and removing tape or film
- Fewer touchpoints = fewer mistakes and less rework
- Consistent results from part to part and job to job
Sharper Detail and Cleaner Edges
- High-definition masking for logos, patterns, micro text, and complex geometry
- Repeatable edge definition - especially valuable on visible, decorative surfaces
Designed for Finishing Workflows
- Mask stays stable during mechanical surface treatment (grinding, brushing, sandblasting)
- After processing, it removes in a controlled wash step - no scraping, no residue chase
Flexible: Decorative + Functional
- Decorative effects on brushed metal
- Functional masking for grounding points, contact areas, and protected zones
What You Can Produce
Glossy Graphics on Brushed Metal
Create glossy patterns or logos that stand out on brushed aluminium - ideal for:
- Premium panels
- Nameplates
- Enclosures
- Architectural components
Selective Masking Zones
Mask off precise zones for surface treatment:
- Grounding/contact points
- Fit surfaces
- Assembly interfaces
- "Do-not-treat" areas
Digital Stencils for Blasting
Print fine details for sandblasting work with crisp boundaries and consistent repetition.
Optional Color Printing
Add color where needed - while keeping surrounding surfaces protected for subsequent finishing steps.
How the Process Works
Digital Pattern Printing
Your design is printed directly as a masking layer using UV-curable masking fluid.
LED-UV Curing
The mask cures instantly for stable handling and predictable performance.
Surface Treatment
Proceed with your operation: grinding, brushing, sandblasting, or other surface finishing.
Mask Removal
Remove the mask in an alkaline water bath (or agreed wash method), revealing sharp, clean protected areas.
Result: a high-quality finish with precise masked geometry - without the manual masking bottleneck. See results in our gallery.
The Process in Pictures
Where It Fits Best
This is a strong match if you have:
- Frequent design changes, variants, or short runs
- High labour cost tied up in masking steps
- Quality issues from manual alignment or tape edges
- A need for finer detail than cut film can deliver
- Premium surfaces where edges and cleanliness matter
Quality and Repeatability You Can Rely On
Digital masking is built around process control:
- Consistent print geometry from approved artwork
- Predictable curing and handling
- Repeatable results across operators, shifts, and production lots
- Fast changeovers without new cutting files or weeding
If you're tired of "it depends on who masked it," this is the step-change. Talk to us.

FAQ
It's commonly used on aluminium and other suitable metal substrates depending on surface condition and process steps.
The mask is designed for mechanical surface treatments such as brushing, grinding, and sandblasting, within validated process limits.
Typically via an alkaline water bath (or defined wash process), leaving protected areas clean and sharply defined. See the full process.
When processed and removed correctly, the goal is clean removal with minimal cleanup - validated during pilot testing on your parts.
Yes. We support workflow definition, artwork preparation rules, and process parameters so results remain consistent. See our recommended equipment.
