This method of using leather to make items has continued to this day. The existing traditional animal Although the leather leather is decorated with patterns, it is quite monotonous in terms of aesthetics in a single color, and it reduces the attractiveness of modern purchases in terms of colorful fashion.

With the advancement of technology today, artificial leather is produced. Because artificial leather is easy to make and cheap, the use of artificial leather has increased greatly. In addition to the traditional way of making items, it is also used for baseball, ball games, football, volleyball, leather bags and belts. In terms of products, these leathers can be pre-selected in material, type, color, printing, branding, ironing, text, image relief, trademark and leather grain, this kind of appearance is opaque material, and it is a single color or just a variety of single colors There is nothing special about the leather, so color or branding is often added to the leather surface, and the image is printed on the leather directly by screen printing or transfer printing, and then high-frequency or bronzing is used as needed Machine branding processing method, the pattern is pressed into relief.

The above are all methods of placing color images on the leather surface, but have the following disadvantages:

1. As the item is used, the color image will wear, degrade, and disappear.

2. The printing method is traditional screen printing, the image resolution and color printing are very limited, the image quality is rough, not refined enough, the color is not bright enough, and it is impossible to print natural full-color images with a resolution of more than 1 million pixels.

3. The background color of the leather limits the vivid quality of the color image.

4. Multi-color screen printing is more expensive and the production speed is slower.

5. Although full-color photo images can be obtained through thermal transfer printing, the production process is complicated and the cost of plate making is expensive. In addition, the images are set on the surface, which causes the images and colors to be easily worn, degraded and lost due to contact.

Based on the above discussion, the current use of leather to set the color image is missing, which is insufficient to meet the needs of today's consumers, and further improvement is urgently needed.
