Identification ribbon

To identify the level of quality ribbon mainly from tape-based, joint welds and ink three.
With base

star printer ribbontape substrate is woven nylon fiber as raw material, its quality directly affects the poor adhesion of the ink ribbon life and penetration. On the use of market-based band is divided into nylon 6 and nylon 66, the difference lies in the different chemical composition of nylon. Nylon 66 is better than nylon 6 elastic, durable resistance to fight. Nylon 66 is divided into a low density, the higher the density, high-density and high-density four twisting, density, warp and weave a few more elastic as possible. Preferred ribbon is generally used in high-density nylon 66 woven, warp and weft density of more than 130 lines per centimeter, fiber state no winding, lint-free, non-deformable high density tape substrate.
Ink

Good ink small particles will not clog pinholes, good liquidity, PH value even when inking strong adsorption moisture is good, durable color transition play and print slowly. The quality of the ink ribbon is through a degreasing treatment, hand to touch when the process will not leave the ink obvious traces of ink this ink is very uniform on the finger, and after the printing effect is not obvious difference.
Interface

Good flat ribbon interfaces were thin, the error is relatively small, the degree of hardening is very light, when the printing is not linked to needle; greater seam strength, tensile strength is also strong. Ribbon quality welds are welded using ultrasonic waves, it is possible to effectively guarantee the quality of the joint, and using a simple hot pressing method or a hot-melt seam welding are varying degrees of damage of the fiber properties with the group, resulting in welding was protruding joints will show a double header, and the interface is very smooth, which is often used print ribbon pin can not be returned, so badly worn, damaged or broken print needle, so the purchase should be carefully observed ribbon case the joint weld
