What is meant by a graphic constraint?

A graphic constraint refers to limitations or specifications that guide the design process, such as size, format, or other specific parameters. Locking a graphic to a certain size is a clear example of a graphic constraint because it establishes boundaries within which the design must operate. This ensures that the graphic will fit appropriately within a given space, maintains the visual integrity of the design, and adheres to any logistical requirements related to printing or display.

The other options involve decisions in the design process but do not inherently establish strict limitations. Setting a design deadline is more about time management than a constraint on the graphic itself. Choosing a color palette involves selecting colors, which influences the aesthetic but does not restrict physical aspects of the design. Changing the layout of a design might affect the overall presentation, but it does not impose a fixed condition that must be adhered to, unlike predefined size constraints.
