What is a substrate in printing?

A substrate is a material that is used as the surface or base for printing. In the printing industry, the term substrate refers to the material that is being printed on, such as paper, cardboard, film, or fabric. Substrates are chosen based on the desired characteristics of the final printed product, such as weight, thickness, finish, and texture.

Different types of substrates are suitable for different printing processes and applications. For example, paper is a common substrate for printing documents, brochures, and other printed materials, while film is often used for printing labels and packaging materials. Fabric is a popular substrate for printing garments and other textiles, while plastic or metal may be used for printing signs and other durable products.

In addition to the material, the surface finish of the substrate can also be important. Some substrates, such as paper, come in a variety of finishes, including gloss, matte, and satin, which can affect the appearance of the final printed product. Choosing the right substrate is an important part of the printing process, and can have a significant impact on the quality and appearance of the final printed product.
