Aluminum litho, also known as lithographic aluminum or litho aluminum, is a type of aluminum sheet specifically used in the printing industry, primarily for offset lithography. It is designed to have a smooth, grained surface that is receptive to ink and other printing substances.

In the lithographic printing process, aluminum litho sheets are utilized as the printing plates. Ink is applied to the litho plate, transferred to a rubber blanket, and then onto the final printing surface, such as paper or cardboard. The smooth and ink-receptive surface of aluminum litho ensures precise ink transfer, resulting in high-quality prints with sharp details and vibrant colors.

When it comes to scrap, aluminum litho scrap refers to discarded or recycled lithographic aluminum sheets. These can be collected from printing facilities or other sources involved in lithographic printing processes. The recycling of aluminum litho scrap is beneficial for resource conservation, as aluminum is highly recyclable and retains its properties during the recycling process.

Recycling aluminum litho scrap involves sorting, cleaning, and processing the material to extract the aluminum content. The recycled aluminum can then be used to produce new aluminum sheets or other aluminum products, reducing the need for extracting and refining raw materials.

In summary, aluminum litho refers to aluminum sheets specifically designed for lithographic printing. They possess a smooth, ink-receptive surface that facilitates high-quality printing. Recycling aluminum litho scrap contributes to resource conservation and promotes the sustainable production of new aluminum materials.
