Creating a custom challenge coin starts with good artwork. Before a manufacturer can prepare tooling, the design needs to be converted into a format that clearly communicates shapes, text, colors, borders, relief areas and other production details.
Customers often ask whether they should send an AI, EPS, SVG or PDF file. The answer depends on how the artwork was created and whether the file contains editable vector information.
For custom challenge coins, vector artwork is generally preferred because it allows the manufacturer to inspect and modify individual design elements more accurately before tooling.
This guide explains the most common artwork formats and what buyers should prepare before sending a design to a challenge coin manufacturer.
Why Artwork Format Matters for Custom Challenge Coins
A challenge coin is not produced directly from a normal image file.
The manufacturer may need to convert the artwork into production information for:
- Tooling
- 2D relief
- 3D modeling
- Metal borders
- Enamel areas
- Text
- Plating
- Custom edges
- Cutouts
- Serial numbers
If the artwork is difficult to edit, the manufacturer may need additional artwork preparation before production.
A good production file helps reduce:
- Design misunderstandings
- Text errors
- Incorrect proportions
- Missing details
- Color confusion
- Unnecessary artwork revisions
What Is Vector Artwork?
Vector artwork is created using mathematical paths rather than fixed pixels.
This means the artwork can usually be enlarged or reduced without losing the sharpness of the shapes.
Common vector formats include:
- AI
- EPS
- SVG
- Some PDF files
For challenge coin manufacturing, vector artwork is particularly useful for:
- Logos
- Text
- Geometric shapes
- Borders
- Icons
- Simple illustrations
AI Files for Challenge Coin Manufacturing
AI stands for Adobe Illustrator Artwork.
It is the native file format associated with Adobe Illustrator.
For professional custom metal manufacturing, an AI file can be extremely useful because it may contain editable:
- Vector paths
- Text
- Shapes
- Layers
- Colors
- Design elements
Why Manufacturers Like AI Files
An editable AI file can make it easier to:
- Separate colors
- Adjust borders
- Modify text
- Simplify details
- Prepare tooling
- Identify individual design elements
If your designer created the challenge coin artwork in Adobe Illustrator, sending the original AI file can be a good option.
EPS Files for Challenge Coin Artwork
EPS stands for Encapsulated PostScript.
EPS is another widely used vector format.
It has historically been popular for:
- Logos
- Corporate artwork
- Printing
- Signage
- Manufacturing graphics
An EPS file can contain scalable vector paths that are useful for preparing challenge coin artwork.
When EPS Is Useful
EPS works particularly well when the artwork contains:
- Company logos
- Organization emblems
- Text
- Simple illustrations
- Geometric borders
However, the quality of an EPS file depends on how it was originally created.
An EPS containing a low-resolution raster image is not equivalent to a true vector EPS.
SVG Files for Challenge Coins
SVG means Scalable Vector Graphics.
SVG is widely used for web and digital design but can also be useful for manufacturing artwork when it contains genuine vector paths.
Advantages include:
- Scalable graphics
- Clear paths
- Editable shapes
- Small file size
- Easy digital transfer
SVG can work particularly well for:
- Logos
- Icons
- Simple symbols
- Typography
- Geometric designs
However, some SVG files may contain unsupported effects, fonts or embedded images.
For manufacturing, the file should be reviewed rather than assuming every SVG is production-ready.
PDF Files for Challenge Coin Artwork
PDF is one of the most commonly exchanged design formats.
A PDF can contain:
- Vector paths
- Text
- Images
- Shapes
- Color information
However, not every PDF is a vector file.
For example:
Vector PDF
Contains editable vector paths.
Image-Based PDF
Contains a JPG or PNG placed inside a PDF.
These two files may look identical on screen but provide very different manufacturing possibilities.
Which File Format Is Best?
There is no single format that is always best.
For professional challenge coin production, a practical preference is:
AI / EPS / SVG → Editable Vector PDF → High-Resolution PNG/JPG
The first choice should be an editable vector file whenever available.
| Format | Vector Capable | Easy to Edit | Recommended |
|---|---|---|---|
| AI | Yes | Excellent | ⭐⭐⭐⭐⭐ |
| EPS | Yes | Good | ⭐⭐⭐⭐⭐ |
| SVG | Yes | Good | ⭐⭐⭐⭐ |
| Sometimes | Depends | ⭐⭐⭐⭐ | |
| PNG | No | Limited | ⭐⭐⭐ |
| JPG | No | Limited | ⭐⭐ |
The table is a practical manufacturing guideline rather than a strict industry standard.
AI vs EPS vs SVG vs PDF
AI
Best for: Professional Illustrator artwork
Strength: Editable design structure
Consideration: Requires compatible design software.
EPS
Best for: Logos and traditional vector artwork
Strength: Widely supported
Consideration: File structure can vary depending on how it was exported.
SVG
Best for: Modern vector graphics and logos
Strength: Scalable and lightweight
Consideration: Some effects or fonts may not transfer perfectly between software.
Best for: Sharing approved artwork
Strength: Easy to view and distribute
Consideration: The PDF may contain either vector artwork or only a raster image.
What About PNG and JPG?
PNG and JPG files are raster images.
They are made from pixels rather than scalable vector paths.
They can still be useful for:
- Design references
- Product concepts
- Photographs
- Artwork previews
- Simple logos
But they are generally less convenient for directly preparing production tooling.
Example
A customer sends:
2000 × 2000 px PNG
The image may look sharp on a monitor but become difficult to work with when the manufacturer needs to isolate tiny shapes and convert them into metal relief.
What Resolution Should Artwork Have?
For vector artwork, resolution is not normally the main concern because vector paths are scalable.
For raster reference images, higher resolution is better.
A low-resolution image can make it difficult to determine:
- Small text
- Thin lines
- Logo details
- Facial features
- Border shapes
If only a raster image is available, send the highest-quality original version you have.
Should Text Be Converted to Outlines?
Yes, when preparing vector artwork for production, converting text to outlines can help avoid font substitution problems.
For example, a design using:
Arial
could display differently if the manufacturer’s computer does not have the same font installed.
Converting the letters into vector outlines turns the text into shapes.
This helps preserve:
- Letter shape
- Font appearance
- Spacing
- Proportions
However, keeping an editable version of the original text separately can also be useful for future revisions.
What Are Outlined Fonts?
Outlined fonts are no longer treated as editable text.
Instead, each character becomes a vector shape.
For example:
CHALLENGE COIN
becomes a series of vector paths.
This can be useful during manufacturing because the exact letter shapes are preserved.
Should Colors Be Specified?
Yes.
Do not rely only on how a color looks on your monitor.
For branded products, provide color references whenever possible.
For example:
- Pantone reference
- Brand color specification
- Manufacturer-approved sample
This is particularly important for:
- Corporate logos
- University colors
- Police department colors
- Military unit colors
- Event branding
Artwork Should Separate Different Production Areas
A good challenge coin design should make it relatively clear which areas are:
Metal
Enamel
Raised relief
Recessed relief
Background
Cutout
For example:
Front
Raised eagle
Background
Recessed metal
Color
Blue soft enamel
This information helps the manufacturer understand how the artwork should be translated into a physical product.
Artwork for Soft Enamel Challenge Coins
Soft enamel coins require clear recessed color areas.
The artwork should show:
- Metal borders
- Color sections
- Text
- Background
- Raised areas
Avoid extremely tiny color sections that may be difficult to fill consistently.
Artwork for Hard Enamel Challenge Coins
Hard enamel artwork should also clearly identify the intended color areas.
Because hard enamel creates a smooth finished surface, the manufacturer needs to know exactly where the enamel will be applied.
Artwork for 3D Challenge Coins
3D artwork requires more than simply sending a flat logo.
The manufacturer may need to interpret:
- Height
- Depth
- Contours
- Sculptural features
- Surface transitions
A reference image can be extremely helpful.
For example, if you’re creating a 3D K9 coin, provide a clear reference photo showing the dog’s facial structure.
Artwork for Custom-Shaped Challenge Coins
Custom-shaped coins require a clearly defined outer contour.
The file should identify:
Final coin outline
rather than simply placing a logo inside a standard circle.
Examples include:
- Aircraft
- Shields
- Animals
- State outlines
- Tools
- Buildings
- Vehicles
Artwork for Cutout Challenge Coins
If your design includes an opening, the cutout should be clearly identified.
For example:
Metal
→
Open Area
→
Metal Bridge
This allows the manufacturer to evaluate whether the remaining metal sections are sufficiently strong.
Artwork for Double-Sided Challenge Coins
Double-sided coins should clearly separate:
Front
Primary artwork
Reverse
Secondary artwork
Also specify the desired orientation between the two sides.
This is especially important when the design contains:
- Text
- Flags
- Directional symbols
- Aircraft
- Portraits
- Logos
Artwork for Numbered Challenge Coins
If the coins require sequential numbering, provide a clear numbering specification.
Example:
001–500
or:
No. 001 / 500
For personalized projects, provide the information in a verified spreadsheet when appropriate.
Common Artwork Problems
1. Low-Resolution Logo
A small JPG may not contain enough detail for production.
Solution
Request the original vector logo from the designer.
2. Fonts Are Not Outlined
The manufacturer may not have the same font.
Solution
Convert production text to outlines.
3. Too Much Tiny Detail
Small details may not reproduce clearly.
Solution
Simplify the artwork before tooling.
4. Colors Are Not Clearly Defined
Different people may interpret colors differently.
Solution
Provide color references.
5. Artwork Contains Too Many Effects
Gradients, shadows and transparency may not translate directly into metal.
Solution
Convert visual effects into practical metal and enamel structures.
6. Front and Reverse Are Not Clearly Identified
This can cause orientation problems.
Solution
Label each side clearly.
7. No Final Dimensions
The manufacturer does not know how large the coin should be.
Solution
Specify:
Diameter + Thickness
or provide the exact custom dimensions.

What Should You Send to a Challenge Coin Manufacturer?
If you have the original design package, the ideal submission can include:
1. Vector Artwork
AI, EPS or SVG.
2. Reference PDF
A PDF showing the approved appearance.
3. High-Resolution Preview
PNG or JPG for quick reference.
4. Production Specifications
Include:
- Size
- Thickness
- Material
- Finish
- Enamel
- Edge

5. Reference Images
Useful for complex 3D designs or custom shapes.
Providing multiple file types can actually reduce communication problems because the manufacturer has both editable artwork and an easy-to-view visual reference.
Example Artwork Specification
A customer might provide:
Product: Custom 3D Challenge Coin
Diameter: 45 mm
Thickness: 3 mm
Material: Zinc alloy
Front: 3D eagle
Reverse: Organization logo
Enamel: Blue soft enamel
Finish: Antique silver
Edge: Rope edge
Quantity: 500 pcs
Artwork: AI + PDF + PNG
This gives the manufacturer much more useful information than simply sending a single image.
How Artwork Quality Affects the Final Coin
The relationship can be summarized as:
Better Artwork
↓
Better Engineering Interpretation
↓
Better Tooling
↓
More Accurate Metal Details
↓
Better Finished Challenge Coin
This is why artwork preparation should be treated as part of manufacturing rather than just a graphic-design task.

Frequently Asked Questions
Is AI the best file format for challenge coin manufacturing?
AI is an excellent option when the artwork was created in Adobe Illustrator and contains editable vector paths. EPS and SVG can also be useful.
Can I send a PDF instead?
Yes. A PDF can be useful, especially as an approved visual reference. However, confirm that the PDF contains vector artwork rather than only a raster image.
Can I send a PNG or JPG?
Yes, especially if that is the only artwork available. However, vector artwork is generally easier for production preparation.
Should fonts be outlined?
For production artwork, outlining fonts helps preserve the exact letter shapes and avoids font-substitution problems.
Do I need to provide Pantone colors?
Not always, but color references are useful when accurate branding is important.
Can a manufacturer create a 3D coin from a 2D logo?
Often yes. A 2D logo can serve as the starting point, but additional modeling may be required to turn it into a suitable 3D relief design.
What if I only have a low-resolution image?
Send the highest-quality image you have. The manufacturer can assess whether it is sufficient or whether additional artwork reconstruction is needed.
What artwork should I send for a custom-shaped coin?
Provide a clearly defined outer contour together with the internal artwork.
Should I approve the artwork before the mold is made?
Yes. Review the final digital proof carefully before tooling begins, particularly the text, dimensions, colors, front/reverse orientation and relief structure.
Final Thoughts
The best challenge coin artwork is not simply the artwork that looks good on a computer screen. It is artwork that can be accurately translated into metal, enamel, relief and finishing processes.
For most custom challenge coin projects, start with:
AI / EPS / SVG
and provide a PDF or high-resolution PNG preview when useful.
Then clearly communicate the:
Size + Thickness + Material + Finish + Enamel + Edge + Relief + Quantity
For complex 3D, cutout or personalized designs, additional production notes and reference images can make the engineering process much easier.
The most important step is to review and approve the final production proof before tooling. This is the best opportunity to catch design problems before they become manufacturing problems.
