How UV Print Medals Are Made: 5-Step Factory Process Explained

UV print medals are made through a controlled factory process, not by simply placing an image on metal. The final result depends on artwork quality, print area planning, metal blank preparation, surface cleaning, UV flatbed printing, curing, epoxy protection and final QC. UV printing is suitable for full-color artwork, gradients, photos, detailed sponsor logos and complex medal designs that are difficult to separate into enamel colors. This guide explains the 5-step UV print medal process from a manufacturer’s perspective, helping brands and procurement managers understand what to check before sample approval and bulk production.

UV printed medals are useful when a medal design needs full-color artwork, gradients, small logos or photo-style details. But stable production depends on file quality, surface preparation, print positioning, curing, epoxy control and QC. Buyers should review these points before approving bulk production.

Key Takeaways:

• UV print medals are suitable for full-color artwork, gradients, photos, detailed logos and sponsor-heavy medal designs.
• The UV print medal process starts with artwork checking because print clarity depends heavily on file quality, resolution and print area planning.
• Metal blank preparation is critical. Dust, oil, polishing wax or uneven surfaces can affect ink adhesion and print quality.
• UV printing uses UV-cured ink and fast curing, and epoxy dome protection is often added to improve surface protection.
• QC should check color deviation, print alignment, detail sharpness, scratches, epoxy bubbles and consistency across the bulk order.

Why UV Printing Is Used for Custom Medals

UV printing is used when a medal design needs color detail that traditional enamel cannot easily reproduce. It is especially useful for gradients, photos, route maps, city illustrations, sponsor logo walls and artwork with many small color areas.

For buyers, UV printing should be selected based on artwork needs. If the design has clean color blocks and raised metal lines, soft enamel may be more suitable. If the design has full-color graphics, shaded artwork or many sponsor logos, UV printing can be the more practical production method.

UV printing can also be combined with soft enamel, 3D relief, plating and epoxy protection. For example, the medal front may use soft enamel and metal lines, while the back side uses UV print for sponsor logos or event details.

Step 1 — Artwork Check and Print Area Planning

UV print production starts before the medal reaches the printer. The first step is checking whether the artwork is suitable for printing on a metal medal surface. File quality, resolution, color planning and print area shape all affect the final result.

For UV printed medals, we check the artwork before sample production so that the print is not blurred, misaligned or too small to read. This is especially important for sponsor logos, small text, gradients and photo-style designs.

A practical UV print output reference is 1440dpi for detailed artwork. This does not mean every artwork will automatically look sharp. If the file itself is low resolution, increasing print settings cannot recover missing image detail.

For dark metal bases such as black nickel or dark antique finishes, the production team may need a white ink layer under the printed color. Without a white base, bright colors can look weaker because the metal background affects the visual result.

The print area should also be reviewed early. UV printing works best on flat or mostly flat areas. If the medal surface has deep relief, strong curves or uneven areas, the print area may need to be adjusted to avoid distortion or loss of detail.

Step 2 — Medal Blank Preparation and Surface Cleaning

The second step is preparing the medal blank. A UV printed medal may start as a zinc alloy die-cast medal, stamped metal medal or another custom medal base. Before printing, the metal blank must be inspected, cleaned and positioned correctly.

Surface condition matters because UV ink needs a clean and stable surface. Dust, polishing wax, oil, fingerprints, water marks or plating defects can affect adhesion and print quality.

In factory production, the printing area must be cleaned before UV printing. If polishing wax remains on the surface, the printed layer may not bond well. If dust is left on the medal, it may appear as spots under the printed or epoxy-protected area.

For batch production, positioning is just as important as cleaning. A fixture or jig helps each medal sit in the same location on the UV flatbed printer. Without stable positioning, the print may shift slightly from piece to piece, especially on irregular-shaped medals.

UV printing is only one part of the medal production chain. If you want to review the full process before the printing stage, see our guide on how race medals are made .

Step 3 — UV Flatbed Printing and Color Control

After artwork approval and blank preparation, the medals are placed on the UV flatbed printer. The printer applies UV-curable ink according to the artwork file, and the image is printed directly onto the medal surface.

For custom medal orders, the key control points are alignment, color visibility, print clarity and batch consistency. UV printing is not only about whether the image can be printed. It is about whether the image stays readable, centered and consistent across the bulk order.

When printing on dark plating, a white ink base can improve color saturation. Without it, red, yellow, blue or other bright colors may look dull because the metal base shows through visually.

Small sponsor logos and fine text should be checked with close-up photos. A logo that looks readable on a screen may be too small once printed on a medal, especially if the print area is small or the artwork has many logos.

Color should be confirmed through a sample because metal base color, ink, lighting and epoxy protection can all affect appearance. We do not recommend approving a UV printed medal only from a digital mockup when color accuracy matters.

Step 4 — UV Curing, Epoxy Protection and Surface Finish

After printing, the UV ink is cured by UV light. This allows the printed image to set quickly and move into the next production stage. For many custom medals, a transparent epoxy dome is added over the UV printed area to improve surface protection and gloss.

Epoxy is not required for every UV printed medal, but it is common when the printed area is on the front side or may be touched frequently. Epoxy can protect the printed layer from scratches and create a smooth glossy surface.

A common epoxy dome thickness reference is around 0.5–1mm, depending on the medal shape, print area and finish requirement. The epoxy area must be controlled carefully. If the dome is too thick, it may look uneven or affect the edge. If the epoxy flows beyond the intended area, it can cover metal lines or create a messy boundary.

Before epoxy is applied, the printed surface should be clean. Dust, small fibers or particles can become trapped under the epoxy layer. For large printed areas, flow control matters. For small logo areas, edge control is more difficult and should be reviewed during the sample stage.

If the buyer wants a matte surface, epoxy may not create the intended look. In that case, the protection method should be discussed before production.

Step 5 — Final QC, Packaging and Pre-Shipment Check

The final step is inspection, assembly, packing and pre-shipment confirmation. UV printed medals need QC checks that focus on both print quality and medal finishing. A medal may pass basic shape inspection but still fail if the print is blurry, misaligned or scratched.

Before shipment, buyers should review the finished medal under normal light, angled light and close-up views, especially when the design includes small logos, gradients, photo images or epoxy protection.

Badge Artisans uses a 3-stage QC approach for custom medal orders: blank inspection, semi-finished inspection and final inspection. For UV printed medals, final QC should include print clarity, print position, epoxy surface, ribbon assembly and packaging condition.

For international orders, sample and pre-shipment confirmation are often handled through photos and videos. Physical samples can be shipped when strict approval is required, but this adds sample shipping and approval time.

Common UV Print Medal Problems and How We Prevent Them

UV printing can reproduce complex artwork, but it also has its own production risks. Most problems can be reduced by checking the artwork, preparing the blank properly, using stable positioning and reviewing samples before bulk production.

The table below shows common UV print medal issues and the factory controls used to prevent them.

In our factory workflow, UV print risk is controlled before printing begins. We review whether the artwork is suitable, whether the surface is printable, whether a white ink base is needed and whether the print area should be protected by epoxy.

For bulk production, we also check consistency between the approved sample and finished goods. This is important because the buyer is not only approving one sample; the buyer is approving the standard that the entire batch should follow.

When UV Printing Should Be Combined with Other Medal Techniques

UV printing does not need to cover the entire medal. In many projects, the best result comes from combining UV print with other medal techniques. This allows the medal to keep metal texture, enamel color blocks or 3D relief while using UV print only where full-color detail is needed.

Hybrid medal production is useful when one process alone cannot satisfy both the visual design and the manufacturing requirement.

A common race medal solution is soft enamel on the front and UV print on the back for sponsor logos. Another option is a 3D medal with a flat central area reserved for UV printing. This can help preserve the medal’s metal structure while still allowing detailed graphic artwork.

UV printing itself does not create glow-in-the-dark effects. If a glow effect is required, it must be created with glow pigment, glow powder or glow paint. For glitter and glow planning, see our guide on special finish options for race medals .

Decision Checklist for Buyers Before Ordering UV Print Medals

Before placing a UV print medal order, buyers should confirm the artwork, print area, surface condition, sample method, epoxy protection and timeline. These details reduce revision risk and make the quotation more accurate.

Use this checklist before sample production.

A practical decision path works like this:

1. First, check if the artwork needs full-color reproduction. Gradients, photos and detailed sponsor logos usually point to UV printing.
2. Second, check if the print area is flat enough. If the surface is highly raised, recessed or curved, adjust the artwork or reserve a flatter print zone.
3. Third, check the metal base color. Dark finishes may need white ink under the printed colors.
4. Fourth, decide whether epoxy protection is needed. Front-side graphics and high-contact areas usually benefit from epoxy dome protection.
5. Fifth, confirm sample approval method. Photo and video approval is efficient for international orders, while physical samples add time but help when hand feel or internal approval is required.
