UV ink is a specialized ink utilized by UV flatbed printers, but the pliability and hardness of this ink are indeed contingent upon the specific material being printed. For instance, hard materials such as metal, glass, wood, and ceramics necessitate the utilization of tough UV inks when printed with a UV flatbed printer. Conversely, soft materials like mobile phone cases, leather non-woven bags, etc. necessitate the employment of soft ink as these materials are inherently delicate. When printing with hard ink, cracks or even large pieces of the pattern may appear when the product is folded, stretched, or bent. Implementing specialized soft UV ink eliminates such concerns. Soft UV ink is also adept at printing on rigid products. Unfortunately, the cost of soft ink is greater than that of hard ink, which can increase production costs. As a result, it is recommended when purchasing UV ink, one must opt for the appropriate and suitable ink based on their necessities.

The advantages and characteristics of soft ink and rigid ink are as follows: Soft ink possesses a broad range of applications and appreciable advantages such as high color saturation and excellent color reproduction. It displays exceptional water resistance, robust weather resistance, and the outputted images can be preserved for extended periods. Additionally, the printed pattern will not crack when the material is forcefully twisted. Rigid ink, on the other hand, attaches better to comparatively hard materials. The result of inkjet products is glossy, highly saturated, and boasts intense three-dimensional images.

The common scope of use for soft ink includes mobile phone leather cases, leather, advertising cloth, soft PVC, soft rubber cases, etc. Meanwhile, the typical application range for rigid ink is on hard materials like metal, glass, hard plastic, ceramic tiles, plexiglass, acrylic, advertising signs, or it can be used as a composite microcrystalline process.
