Sublimation coated aluminum sheets are the perfect medium for vibrant and lasting photo prints, decorative displays, and custom gifts.
With options in different alloys, finishes, and thicknesses, they provide a balance of aesthetic quality and mechanical strength.
Whether you need A4 size for gift production or large-format panels for wall décor, sublimation aluminum is a smart, durable, and professional solution for all heat transfer printing needs.
What is Sublimation Coated Aluminum?
Sublimation coated aluminum is a special aluminum sheet with a polymer coating that allows images, graphics, and text to be transferred onto its surface using heat and pressure.
This process creates bright, durable, and scratch-resistant prints, making it ideal for photo panels, signage, nameplates, and decorative displays.
It is popular among printing companies, photo studios, and sign manufacturers due to its lightweight, corrosion resistance, and excellent color performance.
