Learn the differences between surface printing and subsurface printing on aluminum. Compare durability, print quality, lead times, and costs to choose the best printing technique for your application.
A custom design can be applied to an aluminium product using one of two printing techniques: surface printing or subsurface printing. In this article, we explain the differences between these methods, so you know which fits your needs best.
With surface printing, the design is printed directly onto the aluminium. The ink remains on top of the surface, meaning you can feel the print when you run your finger across it. One of the biggest advantages of surface printing is that all colours, including white, can be printed.
This is not possible with subsurface printing. However, the design cannot extend completely to the edge of the product. A narrow aluminium border will always remain visible around the artwork.
With subsurface printing, also known as hydro-anodizing, the design is first applied to untreated aluminium. The aluminium then undergoes a chemical anodizing process that seals the artwork beneath the anodized layer. As a result, the print is infused into the aluminum.
This makes the print highly resistant to wear, scratches, water, and weather, making it an excellent choice for products that are used intensively every day. Another advantage is that subsurface printing allows for full-bleed printing, meaning the design can extend all the way to the edges.
The right printing method depends on how the product will be used.

For applications such as industrial nameplates, asset tags, key tags, machine labels, table signs, and identification plates, subsurface printing is generally the preferred choice due to its outstanding durability. Surface printing is an excellent alternative for prototypes, promotional items, and smaller production runs where speed and flexibility are more important.
