Ribbon is a kind of printing consumables that we are more familiar with. From the earliest mechanical impact printers to later computer dot matrix printers, all used ribbons. The composition of the ribbon is very simple. It is made of a base woven with nylon filaments after soaking and dyeing with ink. The working principle of the ribbon is to use the dot matrix striker in the head of the needle printer or the letter striker in the English typewriter to hit the print ribbon to produce a printing effect on the printing paper.
The composition of the ribbon is very simple. It is made of a base woven with nylon filaments after soaking and dyeing with ink. A good ribbon, the base should be durable, elastic, long-term printing without lint, uninterrupted thread, and no edge. Its performance is mainly that the surface of the belt base is flat, without protruding fiber knots, the warp and weft density is uniform and tight, the cutting edge is straight and uniform, and there is no burnt phenomenon. Touch by hand: The tape base is soft and delicate, with a smooth feeling. It has good elasticity and good resilience when pulled. Bad ribbon bases are severely broken and threaded, feel hard when touched, uneven cutting edges, severely burnt at the edges, low elasticity when pulled, poor recovery, often entrained in printing, easy to get ruffled edges, and cause needle plugging , Tape and other phenomena.
