Remark:

- Fineness: < 10 microns

- Viscosity: measured by Zahn No.3 Jis

- Acid resistance:

Dipping into solutions of 3% hydrochloric acid and 7% acetic acid; slightly colouring of solution, but no change in shade of ink film after 30 mins.
- Alkali resistance:

Same result as acid test after 30 mins. Dipping into solution of 2% NaOH at room temperature.

- Water resistance:

Same result as acid test after 30 mins. Dipping into water at room temperature.

A : No change
B : Slightly colouring of solution but no change of shade of ink film
C : Slightly fading of shade of ink film and a little colouring of the solution
D : Fading pretty much

- Light fastness:

Tester: Sun Tester 575

Distance from light source to substance: 300 mm

 Full: high concentration (colour ink : white ink = 1: 0)
 Tint: low concentration (colour ink : white ink = 1:10)

The degree of resistance:

AA : No fading after 60 hours
A : Fading after 35 - 60 hours
B : Fading after 15 - 35 hours
C : Slightly fading after 15 hours
D : Fading much within 15 hours




6. Thinner:

Note: MCH: Methyl Cyclohexane; BA: Butyl acetate; EA: Ethyl acetate



7. Attention for Users:

- Stir well before using.
- The fineness of previously used inks should be tested before using because a long-term storage can cause an ink agglomerate. Only mix 10-30 % previously used inks into fresh inks and sieve carefully by filter screen 100 µm or metal screen 120 mesh.
- Using the ink supply system together filter screen equipment and circulating pump to prevent inks from skinning, foreign matters as well as to stabilize colour strength.
- For the printing with less ink consumption and small printing plate, moisture can be easily introduced due to long contact with air, leading to thickening and filling-in. To prevent these phenomena, slow drying solvent should be used in so far as possible, and humidity of working areas should be controlled at 55 – 65%.
- Ensuring a good blocking resistance, it’s necessary to control adequate drying rate.
Especially for printing a background colour and white, drying conditions should be adjusted precisely.

Medium usage:

For printing, medium is added into inks to decrease colour strength, depends on the cell- deepness of cylinders. Generally, 10 – 15% medium should be mixed into fresh inks. In special cases, the medium content used is a higher ratio. We recommend the medium ratio as follows:
 Medium rate ≤ 10 – 15% : using non-additives medium.
 Medium rate > 15% : using medium with additives.



8. Safety and storage information:

- The products contain flammable liquids. Thus, it’s necessary to keep a working area ventilating or install a exhaust system of ventilation. Keep away from heat, spark/flame, and static electricity.
- Storage and handling at 15-25oC.
- Avoid contact with skin and eyes.
- Shelf life: 6 months after date of manufacture (in condition 15-25oC).
