When selling printing inks on Alibaba.com, understanding the core attributes that define your product is essential for connecting with the right buyers. Printing ink is not a one-size-fits-all product—different applications require different formulations, and buyers search for specific attribute combinations that match their printing equipment and end-use requirements.
Key Attribute Categories for Printing Inks:
1. Ink Type (Technology Base) - This is the most fundamental attribute that determines compatibility and application. The main categories include offset ink for traditional offset printing presses, digital ink for inkjet and laser digital printers, UV ink that cures instantly under ultraviolet light, water-based ink using water as the primary solvent, solvent-based ink using organic solvents, and eco-solvent ink with lower VOC emissions [3].
2. Viscosity - Measured in centipoise (cP), viscosity determines how the ink flows through printing equipment. For offset inks, typical viscosity ranges from 200-400 cP at 25C. Too high viscosity causes poor transfer and ink starvation; too low leads to dot gain and set-off problems [3].
3. Drying Method and Time - Drying mechanisms include oxidation (offset inks), evaporation (solvent inks), absorption (newsprint inks), UV curing (instant), and heat setting (web offset). Drying time typically ranges from 25-45 seconds for offset inks on coated paper [3].
4. Environmental Certification - Key certifications include ISO 14001 (environmental management), FSC certification (sustainable sourcing), VOC compliance, REACH compliance (EU chemical regulation), and eco-labels like Blue Angel or Green Seal [4].
