Domed Decals Production Guide & Resin Doming Machine Solutions
Choose the doming setup by decal layout first: simple flat samples can start semi-auto, repeat sheets fit 3-axis, while mixed outlines, small gaps or outdoor decals may need CCD vision and PU testing.

Custom logo decals, product branding decals, outdoor decals, promotional decals, and sheet-based resin decals.
Machine selection
Semi-auto, DJ771 or CCD vision system matched by layout, volume & positioning accuracy
Recommended resin

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 | Irregular outlines, mixed layouts, or curved/premium parts may require CCD vision positioning or custom fixtures. |
Production Volume | Low, medium, or high-volume production | Production volume affects the recommended machine configuration and automation level. |
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 | Outdoor decals normally require UV-resistant polyurethane resin and suitable printed substrates. |
Common Production Challenges
Understanding these challenges helps you decide whether a semi-auto, 3-axis automatic, or CCD vision-guided setup is more suitable.
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 / Connected Domes
Small decals, narrow gaps or too much resin can cause overflow or connected domes.
Solution:
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.
Outdoor Resin Mismatch
Indoor epoxy may look clear at first, but outdoor or flexible decals may need PU resin and aging checks.
Solution:
Match resin to UV, flexibility, substrate and expected use environment.
Mixed Layout Positioning
Different outlines, small gaps or variable decal placement can make fixed-path programs unreliable.
Solution:
Use CCD vision when decal positions vary, or use 3-axis only for stable repeat sheets.
Purchase Risk Check
What Can Go Wrong If You Choose the Wrong Domed Decals Setup?
Decal doming looks simple, but the wrong setup can create scrap after the artwork has already been printed. Machine choice should follow decal shape, sheet repeatability, resin flexibility and the real use environment.
Risk 01
Wrong machine for mixed layouts
Risk A regular 3-axis program works best with repeatable sheets. If decal positions vary, camera positioning may be needed.
Result Misaligned resin, edge overflow and higher rework on irregular decals.
Risk 02
Wrong resin hardness
Risk Hard epoxy can look clear on flat indoor decals, but flexible or outdoor decals may need polyurethane.
Result Cracking, curling, yellowing or poor long-term durability.
Risk 03
No bubble control
Risk Resin mixing, viscosity and degassing need to match the decal size and dome height.
Result Visible air bubbles under the dome and rejected finished decals.
Risk 04
Poor edge control
Risk Small decals and narrow gaps need stable resin volume and a tested dispensing path.
Result Overflow, connected domes and inconsistent glossy edges.
Risk 05
Skipping sample testing
Risk Printed ink, laminate and adhesive layers can all affect resin adhesion and appearance.
Result Defects only appear after mass production starts.
Best next step: Send real decal samples or printed sheets before final machine selection, especially if the layout contains mixed sizes, small gaps or outdoor-use materials.
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.
Regular Layout Production
3-Axis Automatic Doming Machine
Best for: Regular sheet layouts, repeat orders, stable decal sizes, and medium-to-high volume production.
- High efficiency
- Stable repeat dispensing
- No vision system required
Mixed / High Positioning Risk
CCD Vision-Guided Doming Machine
Best for: mixed outlines, variable placement, small gaps, curved or premium decals, and high-precision positioning.
- Camera positioning
- Fewer alignment defects
- Better for mixed layouts
Recommended Resin Setup
Epoxy Resin
- Excellent clarity and hardness
- Hard surface with high scratch resistance
- Better for indoor decals and rigid glossy surfaces
- Typical curing: 12–24 hours at 25°C
Polyurethane Resin
- Good flexibility and impact resistance
- Better for curved or flexible surfaces
- Better UV resistance for outdoor decals
- Typical curing: 8–12 hours at 25°C
Resin selection depends on product use, required hardness, flexibility, UV resistance, and expected working environment.

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 resin offers excellent clarity, hardness, and scratch resistance, making it suitable for indoor rigid decals with a glossy finish. Polyurethane resin provides better flexibility, impact resistance, and UV resistance, making it a better choice for outdoor use, curved parts, or products that need more flexibility. We offer free sample testing to help you determine the best resin for your specific decals.
How can I avoid bubbles in my resin domed decals?
Air bubbles are one of the most common issues in domed decal production. To reduce them: (1) Use a vacuum degassing system to remove trapped air from the resin before dispensing, (2) follow the correct mixing ratio and mixing method, (3) adjust dispensing speed and needle height, and (4) keep the substrate clean, dry, and level. For polyurethane resin or demanding outdoor decals, an optional vacuum degassing setup is strongly recommended.
Can domed decals be used outdoors?
Yes, domed decals can be used outdoors when produced with the right materials. For outdoor applications, we recommend using polyurethane resin due to its superior UV resistance and weather durability. Additionally, you should use UV-resistant substrates and consider the operating temperature range. Our sample testing service can verify outdoor durability for your specific application.
Which doming machine should I choose for my production?
The right machine depends on the decal layout, production volume, repeatability, required positioning accuracy, and budget. For samples or low-volume simple flat decals, the Semi-Auto Doming Machine is a flexible starting point. For regular sheet layouts with repeat orders, the DJ771 3-Axis Automatic Doming Machine usually offers the best balance of speed, stability, and cost. For irregular outlines, mixed layouts, curved/premium decals, or high-precision positioning, the SJ4060 CCD Vision-Guided Doming Machine is the safer choice. The best way to confirm the setup is to test your actual decal samples before purchase.
