Persiapan produksi
Dye based ink, melarutkan sejumlah dye dalam air, dan diikuti cosolvent, humectant sampai sampai bahan terakhir. Bila perlu temperatur naik maka berikan pemanasan.
Pigment based ink, pigment tidak dapat larut dalam air, dilakukan dengan dispersi dan mixing pigmen dengan high speed dispersing, homogenising dan milling ( ball mill, sand mill, roll mill, agitator mill, henshell mixer, colloid mill) sampai terbentuk dispersi pigmen yang homogen dalam air.

Spesifikasi dan standard
Standar kostumer Standar umum
Standar kostumer1. High ecological standards (safe use) 2. High color strength and good solubility or dispersibility in aqueous inks 3. High brilliancy 4. High surface tension 5. Low viscosity 6. Extremely low content of chloride and sulfate (low corrosion) 7. Ion content in the ppm range for Ca, Mg and Fe (low precipitation) 8. No heavy metals (complying with standard EN71/3 for toys) 9. High temperature stability (for thermal ink jet and bubble jet) 10. High light stability 11. Very good filtering properties (good for stable, long-lasting inks) 12. Registration on all key markets
