What are the attributes ribbon?

The composition of the ribbon is very simple, that is, the ribbon base woven with nylon yarn as the raw material is made after soaking and dyeing with ink. For high-quality ribbons, the base of the ribbon should be durable, elastic, long-lasting printing without lint, uninterrupted lines, and no edge of leaves. Its performance is mainly that the surface of the belt base is flat, without obvious protruding fiber knots, the latitude and longitude organization is uniform and dense, and the edges are straight and uniform, and there is no scorching phenomenon. Touch by hand: A good base can feel soft and delicate, with a very slippery feel. Even if it is pulled, the elasticity is very good, and the restoration is fast. Inferior ribbon bases are severely broken and threaded, feel hard when touched, uneven cutting edges, severe burnt edges, small elasticity when opened, and poor recovery after being stuck, often entrained in printing, and easy to get ruffled edges , Resulting in plugging of needles, tape and other phenomena.

In addition to the tape base, ink is also an important factor affecting the quality of the ribbon. Good ink particles are small, will not clog pinholes, have good fluidity, have a uniform PH value, have strong absorption when applying ink, have good moisture retention, durable printing, and slow color transition during printing. Good ink is organic, non-toxic, will not corrode, has no peculiar smell, does not stick to the dyeing tape, and is easy to dry. The bad ink particles are obviously large, sticky, and not easy to dry. The produced tapes stick to each other, which can easily block the pinholes during printing, and the needles cannot be stretched flexibly, thus breaking the needles. Its judgment method is that when the ribbon with high-quality ink is touched by hand, there will be no obvious ink marks on the fingers. There is no difference between before and after. Inferior inks will feel greasy when touched by hand, and there will be traces of ink on your fingers. It seems that the ink is sufficient, but the color will appear heavy when printing, which means that the hand touches the paper and it will be blurred. . Inferior ink will not only cause poor printing results, but the ink will also enter the print head needle seams along with the print needle guide hole to solidify, which will block the print needle and make the printer unable to print normally. In severe cases, it will also cause the print head needle resistance The printer pin is enlarged and broken, the parallel slot of the printer pin is crushed, the driver chip of the print head or the ribbon motor is damaged.

Inferior ribbons can cause damage to the printer's needles, which is a heavy loss, so don't be greedy for cheap when choosing ribbons.
