Blue vs. White Backing Decal Paper: What Modelers Need to Know
Perfecting your model kits starts with the right decals. Here’s how to choose between blue and white backing decal paper for the best results.
What Is Decal Paper Backing?
If you’re into model kits—tanks, cars, aircraft, or trains—you know how crucial decals are to getting that realistic, final touch. Decal paper comes in a few varieties, and one of the first things you’ll notice is the color of the backing: blue or white. It may seem like a minor detail, but choosing the right one makes a huge difference in how your decals look and how easy they are to work with.
Blue Backing Decal Paper (Clear Film)
Best for: Light-colored surfaces and white-ink printers
- Used with clear decal film where the background needs to be invisible.
- The blue backing helps you see the decal edges during trimming and placement—especially helpful with small, intricate decals.
- If you’re using a printer that can print white (like the ALPS), the blue backing allows you to see white ink designs clearly.
- Ideal for logos, insignias, or numbering on white or light-colored models.
White Backing Decal Paper (White Film)
Best for: Dark-colored models and printers that don’t print white
- Comes with an opaque white film behind your printed design, ensuring colors stay vivid—even on dark surfaces.
- Perfect when your decal design includes white elements and your printer can’t print white.
- Great for license plates, logos, or unit markings on tanks, planes, or cars with darker paint schemes.
Modeling Examples
| Model Type | Recommended Backing |
|---|---|
| WWII Sherman Tank (olive drab) | White backing for stars & unit markings |
| NASCAR stock car (white body) | Blue backing for clear sponsor logos |
| F-16 Fighter Jet (light gray) | Blue backing for low-vis insignia |
| 1950s Hot Rod (black body) | White backing for bold pinstripes or whitewalls |
| HO Scale Boxcar (rust red) | White backing for bright company logos |
Final Tips for Modelers
- If your design includes white areas and you’re using a standard printer (which doesn’t print white), go with white backing decal paper.
- For that “painted-on” look over light surfaces, clear film with blue backing is ideal.
- Always seal your printed decals with a clear coat (like MicroScale Liquid Decal Film) before cutting and applying.
