Recommended resin
Epoxy Resin or Polyurethane Resin (Matched for clarity & durability)
What Are Domed Decals?
Domed decals are printed graphics coated with a clear layer of resin, creating a raised, 3D effect. The dome enhances appearance, protects the print, and increases durability. They are widely used for branding, product labeling, and promotional items.
Clear 3D resin layer creates depth without hiding artwork details
Epoxy or PU resin should be matched to indoor, outdoor and flexible use
Machine choice depends on layout repeatability, small gaps and placement risk
Why Use Resin Doming for Decals?
Use resin doming when decals need a raised glossy finish, protected print surface and stable edge control across real use conditions.
Raised Gloss for Logos
Clear resin adds depth to printed logos while keeping colors, text and small artwork details visible.
Print & Edge Protection
A controlled dome helps protect ink, laminate and decal edges from scratches, light chemicals and moisture.
Repeat Sheet Production
Stable decal sheets can move from manual samples to repeatable 3-axis dispensing when orders become predictable.
Outdoor / Flexible Options
PU resin can be tested for decals exposed to sunlight, bending, moisture or frequent handling.
Production Requirements for Domed Decals
Key parameters to consider before starting your domed decal production.
| Requirement | Options / Range | Notes |
|---|---|---|
|
Decal Material
|
PVC, Polycarbonate (PC), PET, Aluminum, ABS | Surface should be clean, flat, and free from dust or oil. |
|
Product Shape
|
Flat decals, slightly curved parts, irregular outlines, or mixed sheet layouts | Confirm the outline, smallest gap, edge distance and whether each sheet can be located repeatably before choosing the fixture and path setup. |
|
Production Volume
|
Low, medium, or high-volume production | Confirm batch size, repeat-order pattern and changeover frequency; these affect fixture, path setup and loading plan. |
|
Resin Type
|
Epoxy resin or polyurethane resin | Select the resin according to indoor, outdoor, UV resistance, and flexibility requirements. |
|
Dome Height
|
0.5 mm – 6 mm | Typical dome height is adjustable based on decal size, edge design, and resin viscosity. |
|
Use Environment
|
Indoor or outdoor use | For outdoor decals, test a suitable resin formulation and the complete printed substrate under the expected UV, moisture and temperature exposure. |
Production Challenges and Setup Risks
Check these points with final printed decal sheets before choosing the resin, fixture and dispensing path. Include the smallest gap, material stack, layout repeatability and use environment.
Bubbles Under Clear Domes
Transparent decal surfaces make trapped air obvious, especially on larger logos, clear films or higher domes.
Solution:
Use stable mixing, vacuum degassing and controlled needle height before dispensing.
Edge Overflow and Printed Stack Compatibility
Too much resin, narrow gaps or insufficient edge distance can cause overflow or connected domes. Separately, incompatible ink, laminate or adhesive layers can cause peeling or cloudy edges and affect resin edge behaviour.
Solution:
Test final printed sheets; adjust resin volume, viscosity, path offset and sheet spacing before mass production.
Uneven Dome Height
Different decal sizes, sheet flatness or Z-height variation can create visible dome differences.
Solution:
Calibrate Z-height, resin volume and fixture flatness with real decal samples.
Resin and Use Environment
Indoor, flexible and outdoor decals do not have the same hardness, UV or handling requirements; an unsuitable resin can crack, curl, discolor or feel wrong in service.
Solution:
Match resin to UV exposure, flexibility, substrate and expected use environment, then confirm it with aging and adhesion tests.
Positioning Method and Changeovers
Different outlines, small gaps, print shift and frequent changeovers can affect how each sheet is located and how much path setup work is needed.
Solution:
Test the actual sheet, fixture and path setup before production; check for off-centre domes or rework during a representative changeover.
How to Choose the Right Domed Decal Machine & Resin Setup
No single machine fits every domed decal workflow. Match the machine to your decal layout, repeatability, volume, precision requirements, resin type, and budget.
Repeatable sheet layouts
3-Axis Automatic Doming Machine
Saved paths for repeatable loading, including repeatable irregular outlines.
Positioning / Changeovers
CCD Vision-Guided Doming Machine
Camera correction for demonstrated placement variation; on-screen path editing supports irregular-design changeovers.
Recommended Resin Setup
Soft Epoxy Doming Resin
- Clear, glossy dome finish
- Match resin to the decal substrate, required feel and use conditions.
- Better for indoor decals and rigid glossy surfaces
- 308AB-3S1 reference: initial cure in about 10–12 hours and final cure in about 18 hours at room temperature.
Polyurethane Resin
- Good flexibility and impact resistance
- Better for curved or flexible surfaces
- A candidate for outdoor decals after material and aging tests
- 618AB-18 reference: about 24 hours at 25°C, or about 2–4 hours with 60–80°C heat curing.
Resin selection depends on product use, required hardness, flexibility, UV resistance, and expected working environment.
Domed Decal Machine + Resin Selection Table
Use this table as a starting point. Final machine and resin selection should be confirmed with sample testing.
| Decal Production Situation | First Decision Trigger | Recommended Setup | Resin Starting Point | Why It Fits |
|---|---|---|---|---|
| Samples / Changing Designs | Low volume, frequent artwork changes | PJ180 Semi-Auto | Epoxy or PU after sample testing | Flexible start with lower equipment cost |
| Stable Repeatable Sheets | Repeat positions and stable spacing; complex outlines can use a saved path | Desktop 3-Axis or DJ771 by sheet size, space and output target | Epoxy or PU by material and use | Repeatable loading and path reuse |
| Variable Placement / Frequent Irregular Changeovers | Measured print shift, free placement or mixed positions; or frequent irregular-design path changes | SJ4060 CCD Vision-Guided | Epoxy or PU by material and use | Camera correction addresses measured variation; on-screen path tools can simplify irregular-design changeovers |

FAQ About Domed Decal Production
Which resin is better for my domed decals: epoxy or polyurethane?
It depends on the decal material, use environment and required surface feel. Epoxy is a practical starting point for many indoor decals; clarity, hardness and scratch resistance depend on the formulation. Test a suitable polyurethane formulation when flexibility, impact or outdoor exposure matters. Curvature alone does not decide the resin. We offer free sample testing to check the complete printed decal, including adhesion, edge control and cure, before confirming the resin.
How can I avoid bubbles in my resin domed decals?
Air bubbles are common in domed decal production. Check the A/B ratio and mixing method, trapped air, moisture exposure, dispensing settings and the condition of the printed surface. Keep the substrate clean, dry and level. Evaluate vacuum degassing only with a resin-approved procedure and sample results showing that it addresses the bubble source; polyurethane or outdoor use alone does not establish the need for it.
Can domed decals be used outdoors?
Yes, but outdoor suitability depends on the complete decal system: substrate, ink, laminate or adhesive, resin, edge design and actual UV, moisture and temperature exposure. Test the final printed construction and compare a suitable PU formulation before approving production.
Which doming machine should I choose for my production?
Use the selection table above as the starting point. For decals, send a final printed sheet with the actual laminate or adhesive stack, smallest gap and changeover pattern so edge behaviour and setup work can be checked before production.
