Darkness strengthened pigment based black ink, suitable for PGI-830,810,815,5,820,220,320…

 

1,Ink Character：

The better quality bulk inks, the better printing properties(Optical density, edge acuity, bleeding, penetration and so on), the best 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 refill 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.

A, the contrast analysis of viscosity, Ph, conductivity and other properties before and after aging.

Analysis, No great changes taking place in the performance indicators before and after the aging, which indicates that they have pass the test form the perspective of chemical properties with good stability.

B, the test and analysis of particle size and big particle amount before and after aging.

show that both the two inks have excellent stability, the average particle size and big particle amount did not change a lot after aging test.

Conclusion, In general, the two inks have passed the stability assessment of the aging test, the stability of all the physical qualities (viscosity, ph, particle size, big particle amount).

Freezing accelerate test,

Test conditions, Freezing(-18, 3 days), tested after resumption of the room temperature..

A, the contrast analysis of viscosity, PH, conductivity and other properties before and after aging.

Analysis, No much changes taking place in the performance indicators before and afer the aging, which indicates that they have pass the test from the perspective of the chemical properties with good stability.

B, the test and analysis of article size and big particle amount before and aging.

show that the two inks have excellent stability, the average particle size and the big particle amount did not change a lot, after the aging test.

3, The print performance test,

1), test of flow property, use remanufacture cartridge and CISS, Canon IP1980, IP4500, IP4760, flow property is good, print about 500~2000ml with one printerhead.

2), restart property

The ink is stored in the printer for 15days, print, do not need cleaning, good flow stability. Better than Korean ink.

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

4), Good Optical density.

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：

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, he best lightfastness, Storage stability, Long last print head durability.

D、Print properties：best printing properties, Color gamut, resolution, halftone, bleeding, penetration and so on, E、Health & safety：Non-toxic, Non-flammable, No odor（please to refer to MSDS）
