The structure and factors outside of the ribbon

Outdoor ribbon composition is very simple, is to nylon yarn as raw material woven tape substrate through the ink soaked, stained steel. Good ribbons, playing with groups should be durable, elastic, long-time printing lint, continuous line, can not afford lotus leaf edges. Its performance is mainly with the base surface smooth, without protruding fiber knot, warp and weft density homogeneous tight, cutting edge straight and uniform, no Jiaohu phenomenon. Touch: a good soft and delicate with a group, there is a smooth feel. Pull the elastic good, good resilience. Bad break ribbon group snag powerful, feel stiff when touched, the cutting edge uneven, badly scorched band edge, pull the elastic small, recovery is poor, often print entrainment, easy to play flounced produce blocking needle , cassette and so on.

In addition to the tape substrate, the ink ribbon is also an important factor in quality. Good ink particles small enough to not clog pinholes, good liquidity, PH value is very uniform, strong adsorption when inking, moisture is good, the color transition slow play and durable printing. Good organic non-toxic ink does not corrode, does not smell, after transfection with no sticky, easy to dry. Bad ink particles large, sticky sticky, after transfection with dry quit, sticky badly produced between the tape, easy to plug pinholes when printing, so that the needle can not be flexible extension, which will break the needle. Its judgment is to use a high-quality ink ribbon hand to touch the time, will not leave obvious traces of ink on your fingers. There is no obvious difference before and after printing. The poor quality ink, if a hand to touch when feeling greasy fingers full of traces of the ink, the ink appears very adequate, but the color will appear when printed heavy phenomenon, that is touching on paper It will blur. Poor quality ink will not only cause poor print quality, but it can also be printed along the guide pin hole into the scalp sutural print and cured, plug the print needles, causing the printer can not print properly, serious cases can cause print head needle resistance increases broken needle print, printing pin parallel grooves is crushed, the print head or the ribbon motor driver chips were burned and other serious faults.
