Final answer:
The act of installing artwork into a frame is called framing, which may also involve matting and glazing for extra protection and presentation.
Step-by-step explanation:
The act of installing artwork into a frame is referred to as framing. This process typically involves not only placing the artwork into a frame but also may include matting, which is adding a border around the image, and glazing, which is adding a protective glass or acrylic layer over the artwork.
Mounting is another process that can be involved, which refers to adhering the artwork securely to a rigid backing before it is framed to ensure it stays flat and protected.
