As publicity materials, no matter which industry, the focus is nothing more than: audience, selling point, function. Namely: to whom, what to emphasize and what to achieve. Therefore, to make a poster for a stage play, the design point is nothing more than: 1. Conduct audience research, what is your target group, what characteristics this group has, and what kind of content, style and copy will attract this group at the first time. 2. Explain the product (the stage play you want to sell), what is the selling point and how to stand out in the poster. 3. Considering the function of the poster, whether it is used for network communication, subway, newspaper, theater entrance, pre-publicity, or guiding the box office before the performance, the information emphasized will be different. The above is a general law that is universally applicable. Then compared with movie posters, stage posters have several characteristics: 1. Selling points are more concentrated. For stage plays, there are not as many selling points as movies, such as technology, genre and artistic style. Generally, movie posters will be considered, and stage plays are rarely considered. As far as the selling points of stage plays are concerned, the difference from heavy to light is: star actors & masterpieces > famous directors > troupe > performance venues > other selling points. So when sorting out the selling points, according to this contempt chain (Yi ...), see which selling points of the works rank high and stick them on the posters. 2. The audience is narrower. Fewer people like watching stage plays than watching movies. This requires a higher audience analysis. A movie poster can't catch one audience, maybe it can catch another audience, a stage play, and an audience. This is completely blind. 3. Ticket purchasing information is very important for movie posters. No matter what you do, you just need to highlight the selling point of the film itself. The audience knows that they can go to any regular cinema to buy tickets in a relaxed time, but the stage play is different. The general performance is an activity in a specific theater in a short time, so the location, time and ticket purchasing method of the performance need to be further emphasized.
