The printing process of electrode patches is a critical step in the manufacturing process, as it determines the quality and performance of the electrodes. Currently, common printing processes include screen print process, flexographic print process, thermal transfer, and digital printing, each with its own characteristics and advantages.
Flexographic printing is a printing method that uses flexible plates, known for its high printing speed, vivid colors, strong sense of layers, high-speed production, and low cost. In the manufacturing of self adhesive electrode pads, flexographic printing can achieve large-area pattern printing and is suitable for various materials such as paper, plastic, and foam, making it ideal for mass production. The product customized by TOP-RANK for Omron using ODM is produced using flexographic.
Silkscreen printing involves transferring ink through the holes of a mesh to a substrate (such as paper or ceramics) under certain pressure to form images or text. In the production of stimulation pads, screen printing is suitable for special pigments and inks, such as silver chloride printing. However, it is not suitable for large areas and high-resolution printing.
Heat transfer printing is a method of transferring patterns to materials through heat pressing, offering rich patterns, vivid colors, and wear resistance. In the production of electrode patches, heat transfer printing can achieve complex pattern printing, meeting diverse and personalized needs. However, heat transfer printing is more costly and has higher material requirements.
Digital printing is a method that directly outputs from computer files to printing equipment. In the production of TENS unit pads sticky, digital printing allows for rapid and flexible production, suitable for rapid iteration and small batch production needs, such as the cooling electrode patch from TOP-RANK mentioned below. However, digital printing has relatively lower color saturation and wear resistance.
In summary, different printing processes have their strengths and are suitable for different production needs. When choosing a printing process, it is necessary to consider the specific requirements of the product and the production conditions comprehensively.
