What are photos and ink paintings?

Portrait and inkjet are two different advertising techniques, which are also commonly used in the advertising industry.

Portrait is a high-definition photo made by copying, printing or photographing technology, which can be used in product advertisements, people photography and other fields, and can also be displayed in the form of picture books and exhibition boards.

Ink-jet printing is a basic traditional expression technology in advertising industry. Inkjet is to spray patterns and characters directly on the surface of materials with a professional printer to form colorful and realistic patterns. Generally, it refers to the output of outdoor advertising pictures, and the output of a large picture, such as many billboard pictures next to the expressway, is the result of the output of the inkjet printer.
