Arts and crafts design is a comprehensive discipline covering art, literature, history, philosophy and other fields. In modern society, it is more and more closely related to people’s life, such as clothing design, environmental decoration, etc. The major of arts and crafts design is presented to people in the form of art, which brings people more visual enjoyment. The major of arts and crafts design requires people to cultivate solid basic skills of painting, and better grasp the knowledge and skills of combining traditional art and modern technology, so that they can engage in the creation of traditional art and handicraft production in arts and crafts enterprises and related units. In process design, image processing plays a key role. All process information is presented in the form of graphics. However, the current process system platform only provides the image part, which cannot meet the simultaneous processing of graphics and images by users. This paper selected the key links of ceramic industry in process design as the investigation background. The characteristics and new requirements of its process design were deeply researched and developed, and a graphics and image processing system based on process technology was realized, which realized the collaborative work of graphics and images. In the experiment and analysis of image processing, the results showed that the number 1 and number 3 had the highest and lowest accuracy difference, and their values were 0.543 and 0.448. Therefore, it is very necessary to use multimedia and 5G (5th-Generation Mobile Communication Technology) network security repair technology to conduct image processing research on arts and crafts design.
