Regionality of design. Each institutional enterprise has a different regionality, which may be reflected in the historical background of the institution, the cultural roots behind the products or services, and the scope and target of the market. The logo can have obvious regional characteristics; but relatively speaking, it can also have a strong international image. This is often the most difficult place for designers of design companies to grasp; the applicability of logo design. The logo design must be suitable for the visual communication medium used by the institution. Each medium has different characteristics or has its own limitations, and the application of trademarks must be adapted to the conditions of each medium. Consider the shape, size, color and texture. Therefore, the design works have better applicability.
