Store signage design can achieve a highly generalized and strongly attractive "door painting", which plays a vital role in expanding product sales and enhancing customers' intimacy with the store. Facade signs often consist of logos, symbols, fonts and decorative patterns. For customers looking for purchasing targets or visiting shopping malls, the first thing that catches their attention in a bustling commercial center is often the various store signs, large and small. It plays the role of instructions and reminders in the facade, allowing people to understand and recognize the store through the signboard. A store or store has its own specific trademark mark, which is a kind of credibility in commodity exchange and a symbol for identifying the store. Many stores rely on specific logos, colors, special fonts, etc. to let customers recognize and understand their store and leave a deep impression on them. Under normal circumstances, in addition to logos, signboards also have text, which is readable and well communicated. If a signboard is separated from the logo and text, it will leave its fundamental content and lose the possibility of recognition and the meaning of visual communication. Therefore, the expressive nature of words makes signboards only indicative. To a certain extent, the design of the signboard represents the image of the store. When designing, attention should be paid to beautiful and eye-catching shapes, fine and meticulous workmanship, correct and easy-to-read fonts, and intuitive and clear information. With the development of production technology, the production of modern store signs is becoming increasingly diversified, artistic and stunning.
