Is there any trouble with original
ink when I use inkrang¢ā ink? |
|
| |
No not at all, you can use without any run-up operation or
tedious cleaning. |

What kind of quality control
do REDGIANT inkjet products have to undergo? |
|
| |
REDGIANT's quality control begins long before the products
come on to the market. Special storage tests under extreme climatic
conditions guarantee a long shelf life. Quality control take
place at every stage in the production process. The final conrol
involves exeming the colour consistency and physical properties
of the inks. |

 |
How lightfast are inkrang¢ā inkjet
inks? |
|
| |
Here, we must differentiate between indoor (dye-stuff) and
outdoor (pigment) inks. We guarantee 6 months light fastness
for indoor inks and 12 months for outdoor inks. However, these
tests are carried out under extreme climatic conditions. In
a normal environment, the light fastness is twice as high. When
using a laminate with UV portection for outdoor use,the ink
remains lightfast for significantly longer. |

Are REDGIANT inkjet products
manufactured exclusively in Korea? |
|
| |
Yes! This is primarily for practical reasons. Based at the
REDGIANT head office, the inkjet division can take advantage
of the entire infrastructure of the company. This puts us in
a position to offer high-quality products at competitive prices. |

|
|
|
|
|
|
|
 |
I sometimes get the feeling
that the right and left sides do a print-out differ in quality.
Can that be possible? |
|
| |
Yes, when three factors come together:
a printer with print heads mounted in a row
a bi-directional printer mode
a highly absorbent paper
In such a case, the ink coverage differs during the backwards
and fowards movement of the printer carriage and this may cause
this phenomenon. |

Why are original brand cartridges
so expensive? |
|
| |
The inkjet printer marketing has become a "lost leader"
industry. In case of desktop printers,the price of many new
inkjet printers is only slightly higher than the cost of the
ink cartridges in them. People are shocked to find that replacing
a color cartridge and black cartridge can cost upwards of the
price of printer. In purchasing only two sets of original brand
cartridges, you have to pay as your printer. |
|
|
|
|
|
|
|
|
|
 |
Could I believe your inks are
as good as the original ink? |
|
| |
We produce superior inks that have formulated from good ingredients
by our laboratory, almost the same/similar chemicals and physical
properties as the original inks. Using micron technology, which
reduces the phenomena of clogging or precipitation of colorants.
They are with same characters as the original inks. |
|
|
|
|
|
|
|
|
|
 |
Why are your ink cartridges
so much lower in price than those offered by the printer manufacturer? |
|
| |
We can't speak for the pricing policy of others. All of our
ink cartridges are priced as low as possible while still maintaining
our high quality standards and all are warranted. Anyway our
ink cartridges can offer significant savings when compared to
using new original brand cartridges. At the same time, all of
our inks are sufficiently tested before introducing. |
|
|
|
|
|
|
|
|
|
 |
Aren't all inks the same? |
|
| |
(1) All inks are not created equal. From the base of the chemical
composition to colorants and additives, there are many varying
combinations used when ink formulas are composed. Of the three
chemical bases used to formulate inks, water, petrochemical
solvents and oil are used. Water-based inks are common in desktop
inkjet printers, in recent years, found in wide-format commercial
printers.
(2) The colorant, or the substance used to give color to the
ink, is either dye or pigment. Dye, consisting of small molecules,
is soluble and blends with the water-based solution. A water-dye
based ink tints or stains the paper on a molecular level. Because
the dye is composed of single molecules it lays flatter on the
paper surface reflecting light more evenly and appearing more
vivid. However, the smaller molecular structure of the dye-based
ink also allows it to be damaged by UV light more rapidly that
pigmented inks. Pigmented colorant is insoluble. The pigment
consists of much larger molecules than that of the dye, therefore
the reflection of light received from a pigmented print does
not appear as vibrant due to the scattering of the reflected
light. The larger molecules do allow a pigment ink's print to
last substantially longer than a dye-based ink's print.
(3) In recent years hybrid ink consisting of both dyes and pigments
has been introduced to the market. These inks are being used
in the latest line of Epson printers. The hybrid dye/pigment
ink is also referred to as archival inks. The company claims
that their archival inks will last twice as long as pigmented
ink, close to 200 years.
(4) In addition to the chemical base and colorant, inks also
contain additives. Additives may include buffering agents for
control of the inks pH levels, resin for resilience, and humectants
for the prevention of evaporation. Other ingredients added to
many types of ink may include fungicides, surfactants, and biocides.
Each ink formula has a unique formulation of each additive,
again causing dramatic differences in the final outcome. |

 |
Why are some cartridges sold
as "new" and others as "remanufactured"? |
|
| |
Wherever possible, we offer "new" cartridges. However,
for printers where the printhead is incorporated into the body
of the ink cartridge, new cartridges are not possible. That
would violate patents held on the printheads. |
|
|
|
|
|
|
|
|
|
 |
Why are there so many different
cartridges? |
|
| |
(1) The size, shape and number of ink colors of each cartridge
are determined by the printer manufacturer at the time that
the printer is designed.
(2) All of our inks are formulated for each specific printer
to insure that you of the highest quality print results. |
|
|
|
|
|
|
|
|
|
 |
If the colors of my printout
are incorrect like red looks brown, what are possible reasons
for this? |
|
| |
(1) Software configurations are wrong.
(2) The nozzles of the printhead are failing.
(3) Colors have mixed internally in the tank of ink cartridge.
(4) One or more colors going empty. |
|
|
|
|
|
|
|
|
|
 |
Are the colors the same as the
original? |
|
| |
It's OK for practical uses. We cannot say as 'the colors are
same to the Original', but can say as 'the colors are similar'
only. If there are slight variations in color, they can be adjusted
by the softwares or color management system. |

What are OEM ink cartridges?
and compatible ink cartridges? |
|
| |
OEM ink cartridges are manufacturered by the original printer
manufacturer.
Compatible ink cartridges manufacturered by third parties other
than the printer manufacturer which can be used in place of
the OEM ink cartridge. These cartridges work as good as original
cartridges but have lower cost. |
|
|
|
|
|
|
|
|
|
 |
Will a compatible cartridge
damage the printer? |
|
| |
No. All our compatible cartridges have been tested to ensure
no printer damage will occur. Basically, cartridges including
chips are only consumables. If it they do not work well, they
can be easily changed. |
|
|
|
|
|
|
|
|
|
 |
The printer cannot identify
new cartridge installed, how can I do? |
|
| |
You'd better do, following guides.
(1) Take out the cartridge and reinstall again
(2) Use dry cloth or tissue to clean the chip and reinstall
the cartridge
(3) Exchange the chips on the cartridges. |
|
|
|
|
|
|
|
|
|
 |
What does the printerutility
feature "Unknown" mean when using compatible cartridge
with chip? |
|
| |
You can continue, generally it's no impact or influence to
printer performance. |

Solvent based ink is largely
different from water based ink? |
|
| |
(1) Main solvent is volatile organic material, so it can
be easily printed on non-coated media. Acryl or PVC is sufficient
for solvent ink.
(2) But it may harmful for worker who use the ink, because it
has strong smell and includes some carcinogens in solvent, past
time
(3) These days, the solvent is being changed with less-toxic
and less harmful materials.
(4) It only has pigment as colorant. |
|
|
|
|
|
|
|
|
|
 |
What is advantage of Redgiant's
Eco-Solvent ink? |
|
| |
(1) No carcinogens in it, without strong smell.
(2) The pigment colorant is well-dispersed, without sedimentation
for long time-storage.
(3) very rare printhead problems.
(4) complete compatibility for common Eco-Solvent printers with
EPSON printhead series ; Roland/Mutoh/Mimiki, etc. |
|
|
|
|
|
|
|
|
|
 |
Is there Redgiant's another
Solvent ink? |
|
| |
Yes, we have some Solvent inks for Xaar and Spectra printhead
series,
(1) Low toxic solvent in it
(2) The pigment colorant is well-dispersed, without sedimentation
for long time-storage.
(3) very high density in color, in comparison with TOYO ink
in JAPAN. So it can specially fit for Backlit display.
(4) very rare printhead problems. |
