No not at all, you can use without any run-up operation or tedious cleaning.

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.

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.

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.

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.

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.

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

• 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.
• 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.
• 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.
• 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.

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.

• 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.
• All of our inks are formulated for each specific printer to insure that you of the highest quality print results.

• Software configurations are wrong.
• The nozzles of the printhead are failing.
• Colors have mixed internally in the tank of ink cartridge.
• One or more colors going empty.

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

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.

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.

• Take out the cartridge and reinstall again
• Use dry cloth or tissue to clean the chip and reinstall the cartridge
• Exchange the chips on the cartridges.

You can continue, generally it’s no impact or influence to printer performance.

• Main solvent is volatile organic material, so it can be easily printed on non-coated media.
  Acryl or PVC is sufficient for solvent ink.
• But it may harmful for worker who use the ink, because it has strong smell and includes some carcinogens in solvent, past time
• These days, the solvent is being changed with less-toxic and less harmful materials.
• It only has pigment as colorant.

• No carcinogens in it, without strong smell.
• The pigment colorant is well-dispersed, without sedimentation for long time-storage.
• very rare printhead problems.
• complete compatibility for common Eco-Solvent printers with EPSON printhead series ; Roland/Mutoh/Mimiki, etc.

• Low toxic solvent in it
• The pigment colorant is well-dispersed, without sedimentation for long time-storage.
• very high density in color, in comparison with TOYO ink in JAPAN.
  So it can specially fit for Backlit display.
• very rare printhead problems.
