Choosing the Right Rigid Board Material: Foam, Coroplast, ACM, Ultraboard, Aluminum & More

Choosing the Right Rigid Board Material: Foam, Coroplast, ACM, Ultraboard, Aluminum & More

Why Material Choice Matters

When it comes to signage and displays, your design is only as good as the surface it’s printed on. Whether it’s an event backdrop, real estate sign, or retail display, the right rigid board ensures your graphics stay vibrant, durable, and professional-looking.

According to Grand View Research, the global signage materials market is expected to exceed $50 billion by 2030, driven by demand for durable, weather-resistant, and cost-effective print substrates. With so many options—foam board, coroplast, aluminum composite, Ultraboard, and more—choosing the right one can be overwhelming.

At CEPrints.com, we print on a wide variety of rigid materials, each designed for different environments and budgets. Here’s your complete guide to understanding which one best fits your next project.

1. Foam Board: Lightweight and Budget-Friendly

Best for: Indoor signs, presentations, photo displays, and temporary graphics

What it is:
Foam board (also called Foamcore) is made of a lightweight polystyrene foam center with smooth paper faces on both sides. It’s ideal for short-term use where portability and cost matter most.

Key Benefits:

• Extremely lightweight — easy to mount or hang

• Smooth, bright surface for crisp printing

• Perfect for presentations or point-of-purchase (POP) displays

• Cost-effective for large runs

Use Cases:

• Office presentations and trade show displays

• Mounted photography or artwork

• Indoor menu boards or event signage

Pro Tip: Avoid moisture exposure—foam board is not weatherproof. For outdoor or long-term use, consider ACM or Coroplast instead.
