what is ribbon
2022-05-26
Ribbon is a kind of printing consumables that we are more familiar with. From the earliest mechanical impact type English printers to later computer dot matrix printers, ribbons are used. The working principle of the ribbon is to use the dot matrix striker in the head of the dot matrix printer or the letter striker in the English typewriter to strike the printing ribbon to produce a printing effect on the printing paper.
Ribbon Structure
The composition of the ribbon is very simple. For a good ribbon, the base should be durable and elastic, and it should not be lint, continuous, or edged for long-term printing. Its performance is mainly that the surface of the belt base is smooth, there is no protruding fiber knot, the warp and weft density is uniform and tight, the cutting edge is straight and uniform, and there is no scorching phenomenon. Touch by hand: The base is soft and delicate, with a smooth feeling. Good elasticity and good recovery when pulled. The bad ribbon base is broken and the thread is severe, the hand feels hard when touched, the cutting edge is uneven, the belt edge is severely scorched, the elasticity is small when pulling, and the recovery is poor. , cassettes, etc.
ink ribbon
In addition to the base, the ink is also an important factor in the quality of the ribbon. Good ink particles are small, will not block pinholes, have good fluidity, uniform PH value, strong adsorption when ink is applied, good moisture retention, durable printing and slow color transition during printing. Good ink is organic, non-toxic, non-corrosive, has no peculiar smell, is not sticky after dyeing, and is easy to dry. The bad ink particles are large, sticky and sticky, and the tapes will not dry after dyeing. 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 obvious difference between the front and back printing results. For inferior ink, if you touch it with your hand, it will feel greasy and your fingers are full of ink marks. It seems that the ink is very sufficient, but the color will appear heavy when printing, which means that you can touch the printing paper with your hand. It will be blurry. Inferior ink will not only cause poor printing effect, but it can also enter the needle seam of the print head along the guide hole of the printing needle and solidify, blocking the printing needle, causing the printer to not print normally, and may also cause the needle out resistance of the print head in severe cases. Serious faults, such as enlarged and broken printing needles, the parallel grooves of the printing needles being crushed, the printing head driving chip or the ribbon motor being burned out.
