What are plates commonly made from in printmaking?

In printmaking, plates are commonly made from aluminum due to several advantageous properties. Aluminum is lightweight, making it easier for artists to handle during the printmaking process. It has a smooth surface that allows for fine detail, which is essential for producing high-quality prints. Additionally, aluminum plates are resistant to rust and corrosion, making them durable for repeated use in various printmaking techniques, including lithography and etching.

Aluminum plates can also hold etching inks well, enabling consistent ink transfer to paper. The use of aluminum has grown in popularity partly because it is a more environmentally friendly option compared to some other materials, as it can be easily recycled.

While other materials such as wood and steel are also used in printmaking, they do not offer the same combination of weight, durability, and ink retention as aluminum, which makes it the preferred choice in many contemporary printmaking practices. Plastic plates might not provide the same quality or feel, depending on the technique being used.
