Preparing artwork for a custom challenge coin is more than creating an attractive logo or illustration. The artwork must also be suitable for metal tooling, relief, enamel, plating and finishing.
A design that looks excellent on a computer screen may still require adjustments before it can become a physical coin. Thin lines, tiny text, complicated gradients and overlapping details can create manufacturing challenges if they are not addressed during the artwork stage.
This guide explains how to prepare artwork that is easier to manufacture and how to communicate your design requirements clearly to a custom challenge coin manufacturer.
1. Start With a Clear Concept
Before preparing the production file, determine what the coin is supposed to communicate.
Ask:
- What organization is the coin for?
- What is the main symbol?
- Is it for recognition, commemoration or an event?
- Will it be used by a military unit, police department, fire department, K9 team, school, company or association?
- Should the style be traditional, modern or highly detailed?
A strong concept usually has one clear focal point.
For example:
K9 Recognition Coin
Main element → Dog profile
Secondary element → K9 text
Supporting element → Unit name and date
This is easier to manufacture than trying to place ten different major elements on one small coin.
2. Use Vector Artwork Whenever Possible
For professional challenge coin production, vector artwork is generally preferred.
Common vector formats include:
- AI
- EPS
- SVG
- Vector PDF
Vector files allow individual shapes and paths to be edited more easily.
They are useful for:
- Logos
- Text
- Borders
- Icons
- Symbols
- Geometric patterns
A high-resolution PNG or JPG can still be useful as a visual reference, but it is not the same as editable vector artwork.
3. Keep the Original Design File
If possible, keep the original editable file.
For example:
Original AI file
Production PDF
PNG preview
This combination gives the manufacturer both an editable source and an easy-to-review reference.
Don’t overwrite the original artwork after converting fonts or making production changes. Keep a master copy for future revisions.
4. Define the Coin Size
Artwork should be prepared with the final product dimensions in mind.
Common specifications include:
Diameter
Overall thickness
For a custom-shaped coin, specify:
Width × Height
For example:
45 mm diameter × 3 mm thickness
The manufacturer can then evaluate whether the artwork contains enough space for its details.
5. Design for the Actual Coin Size
A logo that looks clear at 300 mm may become difficult to read at 40–50 mm.
Always evaluate the artwork at approximately its intended physical size.
Check:
- Text
- Thin lines
- Small symbols
- Enamel sections
- Borders
- Facial features
- Numbers
This is one of the simplest ways to identify potential manufacturing problems before tooling.
6. Avoid Extremely Thin Lines
Thin lines are one of the most common issues in custom metal artwork.
A line may look perfect digitally but become difficult to reproduce in metal if it is too narrow.
This can affect:
- Borders
- Text
- Feathers
- Hair
- Decorative patterns
- Small logos
Instead of adding more tiny lines, simplify the design and emphasize the most important details.
The practical minimum depends on the coin size, thickness, material, tooling method and overall design, so the final dimensions should be confirmed by the manufacturer.
7. Make Small Text Larger
Small text can become difficult to manufacture and read.
Avoid putting long sentences around a very narrow border.
Instead of:
DEPARTMENT OF SPECIAL OPERATIONS UNIT RECOGNITION
consider using a shorter phrase such as:
SPECIAL OPERATIONS
Shorter text generally provides more room for readable lettering.
8. Convert Fonts to Outlines
When preparing vector artwork, converting fonts to outlines can help preserve the exact appearance of the text.
Without outlining, the manufacturer may not have the same font installed.
The result could be:
Original font
→ different font
→ different letter proportions
→ different finished coin
Outlined text becomes vector shapes, helping maintain the approved appearance.
Keep a separate editable version of the artwork before converting the production copy to outlines.
9. Separate Metal and Enamel Areas
The manufacturer needs to understand which parts of the artwork should be metal and which should contain enamel.
A useful artwork structure can distinguish:
Metal
Raised or recessed metal areas.
Soft Enamel
Color-filled recessed areas.
Hard Enamel
Smooth filled color areas.
Background
The primary metal surface behind the design.
This separation makes production interpretation easier.
10. Keep Enamel Areas Large Enough
Enamel needs sufficient space to be filled cleanly.
Very small color sections can be difficult to reproduce consistently.
Instead of:
Many tiny color islands
consider:
Fewer larger color areas
For example, a firefighter coin may look stronger with:
Red enamel + black metal + raised Maltese cross
rather than dozens of tiny color sections.
11. Be Careful With Gradients
Digital artwork often uses:
- Shadows
- Gradients
- Transparency
- Glow effects
- Blending
- Photographic textures
These effects do not automatically translate into metal and enamel.
A manufacturer may need to reinterpret them as:
Raised metal
Recessed metal
Enamel
Antique finish
or another physical surface treatment.
If you want a gradient-like appearance, discuss the effect with the manufacturer before production.
12. Prepare Artwork for 2D Challenge Coins
2D challenge coins generally use simpler raised and recessed areas.
They work well for:
- Logos
- Text
- Symbols
- Emblems
- Simple illustrations
A clean 2D design should emphasize:
Strong outlines + clear shapes + readable text
rather than excessive micro-detail.
13. Prepare Artwork for 3D Challenge Coins
3D challenge coins require additional planning.
A flat image doesn’t automatically show how every feature should be raised or recessed.
For a 3D design, provide:
- Main reference artwork
- Photos if applicable
- Important depth information
- Front and reverse views
- Examples of preferred visual style
For a 3D eagle, for example, identify the:
- Head
- Wings
- Body
- Feathers
- Background
The manufacturer can then develop a suitable relief structure.
14. Design Cutout Areas Clearly
If your coin contains cutouts, identify them clearly in the artwork.
For example:
Black = metal
White = open cutout
The exact notation can vary, but the important thing is that the manufacturer can immediately identify which areas are supposed to be open.
Also check the metal bridges between cutouts.
Extremely thin connecting sections may require redesign.
15. Prepare the Outer Border
The outer border often contains:
- Organization name
- Motto
- Date
- Unit number
- Anniversary information
Don’t make the border unnecessarily narrow.
A good border should provide enough space for:
Text + metal separation + visual breathing room
16. Plan the Edge Design Early
The edge should not be treated as an afterthought.
Possible options include:
- Flat edge
- Rope edge
- Reeded edge
- Oblique edge
- Custom edge
If you want a rope edge, for example, make sure the front artwork doesn’t visually compete with the edge decoration.
17. Prepare Front and Reverse Separately
For double-sided challenge coins, clearly label:
FRONT
and:
REVERSE
This prevents orientation mistakes.
Also check how the two sides should align.
For example, determine whether the reverse should appear:
Coin orientation
or:
Medal orientation
This matters for directional artwork and text.
18. Check Text Carefully
Before sending the artwork, verify:
- Spelling
- Dates
- Numbers
- Organization name
- Unit designation
- Acronyms
- Motto
- Website or contact information
A spelling mistake discovered after tooling can be much more expensive to correct than one found during artwork approval.
19. Specify Colors Clearly
For important brand colors, provide a reference.
Useful information can include:
- Pantone
- Brand color code
- Existing product sample
- Approved digital color reference
Don’t rely entirely on the appearance of colors on different monitors.
This is especially important for:
- Corporate logos
- University colors
- Police departments
- Military organizations
- Sports teams
20. Consider the Plating Finish
Artwork and plating should be designed together.
Common finishes include:
- Antique gold
- Antique silver
- Bright gold
- Bright silver
- Copper
- Black nickel
For highly detailed designs, antique finishes can create additional contrast between raised and recessed areas.
Bright finishes can produce a cleaner, more reflective appearance.
21. Design With the Final Material in Mind
Common materials include:
- Brass
- Copper
- Zinc alloy
Material selection can influence:
- Weight
- Surface appearance
- Relief structure
- Tooling approach
- Finishing options
The manufacturer can recommend the most suitable material based on the artwork and specifications.
22. Avoid Overloading the Coin
One of the biggest artwork mistakes is trying to include everything.
A small challenge coin has limited space.
If you add:
- Large logo
- Long text
- Multiple dates
- Multiple symbols
- Detailed portrait
- Several color areas
- Complex borders
the result can become visually crowded.
A better approach is:
One primary subject
Two or three supporting elements
Short, readable text
23. Use Negative Space
Negative space is the empty area around design elements.
It can make the coin easier to read.
For example:
Instead of filling the entire background with decorative lines, leave enough metal space around the central logo.
Negative space is particularly useful for:
- Corporate coins
- Modern challenge coins
- Aviation designs
- Custom-shaped coins
- Cutout coins
24. Consider the Coin’s Viewing Distance
A challenge coin is normally viewed close-up, but it still needs to communicate its main design immediately.
Ask:
Can I identify the main symbol in one or two seconds?
If not, the artwork may contain too many competing details.
25. Prepare a Production Specification Sheet
Along with the artwork, provide a short specification sheet.
For example:
Product: Custom 3D Challenge Coin
Size: 45 mm
Thickness: 3 mm
Material: Zinc alloy
Front: 3D eagle
Reverse: Unit emblem
Finish: Antique silver
Enamel: Blue soft enamel
Edge: Rope edge
Quantity: 500 pcs
Packaging: Individual polybags
This can significantly reduce communication problems.
26. Provide Reference Photos for Complex Designs
Photos are especially useful for:
- Portraits
- Animals
- Aircraft
- Vehicles
- Buildings
- Historical objects
If the artwork is intended to reproduce a specific object, send a clear reference image.
For example, for an aviation challenge coin:
Vector logo + aircraft reference photo
is more useful than a low-resolution screenshot alone.
27. Review the Digital Proof Before Tooling
This is one of the most important steps.
Before the mold is made, review:
- Overall shape
- Size
- Text
- Logo
- Front
- Reverse
- Relief
- Enamel
- Border
- Edge
- Plating
- Cutouts
Do not approve tooling until the production proof matches your requirements.
28. Common Artwork Problems to Avoid
Low-Resolution Images
Difficult to convert accurately.
Tiny Text
May become unreadable.
Extremely Thin Lines
May not reproduce correctly.
Unclear Colors
Can create finishing misunderstandings.
Unoutlined Fonts
May cause font substitution.
Excessive Detail
Can make a small coin visually crowded.
Unclear Cutouts
Can cause incorrect interpretation.
Missing Dimensions
Makes engineering more difficult.
No Front/Reverse Labels
Can create orientation problems.

Frequently Asked Questions
What file format should I use for a custom challenge coin?
AI, EPS and SVG are useful vector formats. A vector PDF is also helpful as an approved visual reference.
Can I send a JPG?
Yes. A JPG can be used as a reference, but vector artwork is generally easier to prepare for tooling.
Do I need to convert fonts to outlines?
For production artwork, outlining fonts helps preserve the exact letter shapes.
How detailed can a challenge coin design be?
The practical level of detail depends on the coin’s size, thickness, material and manufacturing process. More detail is not always better.
Can I use gradients?
You can include them as visual references, but gradients may need to be translated into physical metal, enamel or finishing effects.
Should I provide artwork for both sides?
Yes. For double-sided coins, clearly identify the front and reverse artwork.
Do I need to specify the coin thickness?
Yes. Thickness is an important manufacturing specification and should be confirmed before tooling.
Can a manufacturer help modify my artwork?
In many cases, the artwork can be reviewed and adjusted for manufacturing feasibility. Complex 3D designs may require additional modeling or engineering.
When should I approve the final artwork?
Approve the final production proof before tooling begins. Carefully check text, dimensions, colors, relief, front/reverse orientation and other specifications.
Final Thoughts
Preparing artwork for custom challenge coin manufacturing is about more than sending a beautiful graphic.
The best production artwork is:
Clear
Scalable
Well-structured
Manufacturing-friendly
Accurately specified
Start with vector artwork whenever possible, simplify unnecessary details, make text readable, identify enamel and metal areas, specify the coin dimensions and clearly communicate the desired finish.
For 3D, cutout or highly detailed designs, provide reference images and allow the manufacturer to review the engineering before tooling.
A strong workflow is:
Artwork → Production Review → Digital Proof → Tooling → Metal Forming → Finishing → Quality Inspection
Taking the time to prepare the artwork correctly at the beginning can help reduce revisions and make the final custom challenge coin much closer to the design you originally envisioned.
