Anodized aluminum is a popular printing substrate for a variety of reasons. It is strong and lightweight, making it ideal for signs and other applications where durability is a must. Anodized aluminum also has a very smooth surface, which is perfect for printing high-quality graphics. Additionally, anodized aluminum is resistant to corrosion and fading, making it a good choice for outdoor applications.
Anodized aluminum is created by an electrolytic process in which the aluminum is placed in an acidic bath and an electric current is run through it. This process creates a very thin oxide layer on the surface of the aluminum. The thickness of this layer can be controlled, and it is this control that allows for the creation of different types of anodized aluminum.
There are two types of anodized aluminum that are commonly used in printing: clear anodized aluminum and color anodized aluminum. Clear anodized aluminum has no color added to it, and the aluminum itself has a slightly yellowish tint. Color anodized aluminum, on the other hand, has a dye added to the oxide layer, which gives it a wide range of color options.
Anodized aluminum is a popular choice for printing because it is strong, lightweight, and has a smooth surface. It is also resistant to corrosion and fading, making it a good choice for outdoor applications.
Anodized aluminum plates are used for a variety of printing applications because they provide an excellent surface for printing and allow for a wide range of colors and effects to be achieved. When anodized, the aluminum plate‘s surface becomes harder and more resistant to corrosion and abrasion, making it ideal for high–use applications. Anodized aluminum plates can also be printed on both sides, allowing for more design flexibility.
