Why Do Sign Shops Use Digital ACM?
In today’s signage and graphics industry, digital ACM (aluminum composite material) has become one of the most dependable and versatile substrates for wide-format printing. Its smooth, print-ready surface and lightweight construction make it an ideal choice for sign fabricators and shop owners who need consistent, professional-quality results. Unlike temporary materials that warp, fade, or lack durability, digital aluminum composite panels deliver the perfect balance of strength, print quality, and value.
At Piedmont Plastics, we supply industry-leading solutions like Piedmont Sign Grade, AluPOLY® Digital ACM, designed specifically for direct-to-substrate digital printing. Whether you’re producing retail signage, displays, or architectural graphics, digital ACM ensures your projects stand out with sharp, long-lasting results.

What Is Digital Aluminum Composite Material?
Digital aluminum composite material is a specialized version of traditional ACM engineered for digital printing applications. Like standard ACM, it consists of two thin aluminum sheets bonded to a solid polyethylene core. This construction provides excellent rigidity while remaining lightweight and easy to handle.
What sets digital ACM apart is its factory-applied, specially coated surface designed for UV printing and direct-to-substrate printing. The coating ensures superior ink adhesion, vibrant color reproduction, and a smooth, flawless finish without the need for additional preparation.
Key characteristics of digital ACM include:
Print-ready surface for consistent results
Lightweight yet strong construction
Weather-resistant and durable
Cost-effective compared to other rigid sign substrates
The Difference Between Standard and Digital ACM
At first glance, standard ACM and digital ACM may appear identical, but their surfaces are designed for different purposes. For businesses like sign shops, this difference translates into faster turnaround times, reduced labor, and more reliable results for printing applications.
-
Standard ACM
Often used for structural applications, cladding, or fabricated signage. The surface typically requires surface preparation or additional treatments before printing.
-
Digital ACM
Manufactured with a pre-coated, digital print-ready surface, allowing inks to bond directly for high-quality graphics without priming or sanding.

Pros and Cons of Digital ACM vs. Other Print Substrates
When compared with foam boards, PVC sheets, and corrugated plastics, digital ACM offers unique advantages.
Pros of Digital ACM:
Durability: Outlasts foam board or corrugated plastic, especially outdoors
Print Quality: Provides a flawless, smooth surface for vibrant graphics
Rigidity: Won’t warp or bend easily, unlike thinner plastics
Professional Finish: Looks polished, making it ideal for permanent signage
Cons of Digital ACM:
Cost: Slightly higher upfront investment than foam or corrugated substrates
Weight: Heavier than lightweight temporary materials, though still manageable
Not Flexible: Cannot bend or fold like corrugated or thin PVC sheets
