Paperless animation is relative to transmission animation. In fact, it is the whole process of making animation by computer-the creator transmits the original character design, original painting, animation, background design, color distribution and special effects to the computer to complete. It has many advantages such as "low cost, easy learning, high quality and simple output". Because of low investment and low risk, emerging animation companies have generally accepted and adopted paperless animation process.

In foreign countries, traditional animation is also being eliminated at a high speed. Walter Disney officially closed its traditional animation studio in early 2004. Disney Company is not only the founder of paper animation technology, but also the most brilliant paper animation company in the past 60 years. The company not only entered the field of paperless animation a few years ago, but also spent $4 billion last year to acquire Pixar, a famous digital animation studio. Nowadays, the former king of paper animation has completely entered a new era of paperless animation.

At present, many cutting-edge animation companies in China have launched some brand-new animation works with relaxed life or fantasy themes. These animations are novel and unique, and all of them are made by paperless animation technology. Due to the content limitation of mainstream media such as TV and the high publishing cost, most of the cutting-edge animations are spread by online publishing.
