1,Ink Character：

The better quality bulk inks, the better printing properties(Optical density, edge acuity, bleeding, penetration and so on), the better reliability (Water resistance, Lightfastness, Storage stability, Long last print head durability), optimized to corresponding each of cartridges or printers, they are the first choices of CISS inks and compatible cartridges.

Best stability, excellent print quality, appropriate Viscosity、PH、Surface tension、lower conductivity, in sharpness, penetration rate, shorter dry speed, minor bleeding, good compatibility with print equipment, Health & safety.

2, Ink Properties：

Stability analysis,

1) High-temperature accelerate test, the stability of the aging test.

Under the condition of 70 degrees in the accelerate aging for 7 days.

3, The print performance test,

2), restart property

The ink is stored in the printer for 15days, print, without missing lines, no need cleaning, good flow stability. Better than Korean ink.

3), the print pages test, ok. ISO/TEC FCD24711

4), Good Optical density. Darkness strengthened ink

5), good edge acuity,

6),good bleeding with color ink, better than Korean ink.

DIN 33871:2003,and ISO/IEC15775

4, Other test,

1),good water resistance and lightfastness

2),good dye smear resistance, better than Korean ink

3), good highlighter resistance, better than Korean ink

4), no corrosion to the CISS pipe, even after the aging test for the pipeline. For the CISS, the ink with pipeline , an aging test needs to be done.

5),good chip identification performance of the SMD compatible cartridges.

5, Ink Evaluating：（please to refer to ink QA）

A、Color properties：wide Color gamut, brightness, high color density, good color reduction.

B、Physical Properties：appropriate Viscosity、PH、Surface tension、lower conductivity,

C、Storage stability：good compatibility with OEMs, the best lightfastness, Storage stability, Long last print head durability.
