Final answer:
Centering text in design is contingent on the design's goals and the material used, and should be decided with an understanding of its visual impact.
Step-by-step explanation:
The question of whether text should be centered is dependent on the context of the design and is usually addressed within the principles of graphic design. In graphic design, centering text can be effective or ineffective, depending on the overall design goals and the material being used. The readability, the importance of the text within the design, and the type of material or pattern in the background all affect whether centering is the best choice.
One must consider how the material use impacts the design, and how a particular pattern in textiles may interact with centered text. Centered text can provide a balanced, formal look in some instances, but could also lead to a less dynamic or engaging design in others. Ultimately, centering text should be a decision made with a full understanding of the design's purpose and the visual impact it will have.
