The important role of ribbon
It is easy to see from the physical structure of printer
that needle style printers are using the dot matrix
needle on the printer head to knock the ribbon and leave
the ink on the paper. Obviously, the ribbon acts important
role in printing. So the quality of ribbon will directly
cause different printing performance and printer head
life. Let's use the following formula to express the
relation ship between the ribbon and needle printer.
Good ribbon=excellent printing performance=long life
of printer.
Emphasis again, the most importance factor affect the
printing performance and printer life is the quality
of ribbon. It is easy to neglect by user. It is often
to see rugate ribbon is kept to work by lots of user
with cost saving excuse, it seems they forget disorderly
using rugate ribbon will damage the printer head and
will cost their more later. Normally high quality ribbon
can print more than 3 million characters. But the bad
one can just print 100k-200k characters. So it is very
important for user learn how to distinguish the ribbon
quality to ensure long printing life.
How to select ribbon
Generally the main element affect the ribbon quality
is ribbon radicle, welding quality and printing ink.
Hereinafter will show you how they work.
Ribbon radicle----generally it is made up of nylon
and their quality will affect the ink adherence and
penetration. Currently sales on the market is nylon
6 and nylon 66, the main difference of two materials
is different percentage of chemical ingredient. Usually
nylon66 has a high elasticity and long using life, there
are four types—low density, middle density, high density
and high density with twiddle. High density plays high
performance. High-density ribbon has a smooth surface;
good elasticity and high recover ability. For ensure
long using life and good printing performance you do
better chose the ribbon made of nylon 66 and with high
density.
Printing ink
Good printing ink has a smaller granule and good fluidity,
equality PH data, strong adherence and high humidity
keeping ability. Bad printing ink will jam the nozzle
with big granule and difficult to dry after dye. It
is easy to distinguish the ink quality by touching the
surface of ribbon. Bad ink feels a little wet and easy
to leave dirty on your hand.
Welding jointer
Good ribbon has a smooth and slim welding jointer,
low tolerance and light indurations. This kind of ribbon
has a strong strength and high force resistance ability
and act high performance.
Good welding jointer should have more than 30 degree
welding anger, smooth surface and use the ultra wave
welding. So pay your attention to the welding jointer
will ensure you buy high quality ribbon.
