- Light fastness: Light fastness rating is assessed on 1 to 8 Blue Wool scale where 1 = ‘Poor’ and 8 = ‘Excellent’.
- Heat Stability : Heat stability values given indicate the maximum temperature at which the pigment can be stoved for 10 min. on the full shade and in reductions without undergoing any significant change in shade.
- Oil absorption: The oil absorption is determined on the basis of EN ISO 787-5 and given in g linseed oil per 100 gm. pigment.
- Solvent bleeding: The bleeding in solvents is tested using the powder grades and the visual rating given on 1 to 5 Grey scale
where 1 = ‘Heavy bleeding’ and 5 = ‘No bleeding”

Frequently Asked Questions — PIGMENT YELLOW 174
What specific process color standard does PIGMENT YELLOW 174 match for offset inks?
PIGMENT YELLOW 174 (CAS 76233-86-4, CI: PY174) matches the CIE 12-66 standard yellow for process color printing in offset inks. Its chemical formula C₃₅H₃₂Cl₂N₆O₄ delivers high tinctorial strength and high ink viscosity, which are critical for precise color reproduction in four-color process printing. The pigment is recommended specifically for offset ink formulations requiring low warping behavior and resistance to common ink solvents.
How does the chemical structure of Pigment Yellow 174 influence its performance in offset inks?
The chemical structure of PIGMENT YELLOW 174 (C₃₅H₃₂Cl₂N₆O₄) provides the balance between high tinctorial strength and high viscosity needed for stable offset ink rheology. This structure supports low warping applications, meaning the printed substrate remains dimensionally stable during drying. The chlorine atoms in the molecule contribute to improved solvent resistance, making it suitable for heat-set and sheet-fed offset inks that demand fast setting and sharp dot reproduction.
What is the main application recommendation for PIGMENT YELLOW 174 in the printing industry?
The main recommended application for PIGMENT YELLOW 174 is offset printing inks, with full compliance to the CIE 12-66 yellow standard. It is formulated to achieve maximum color strength while maintaining the high viscosity that prevents misting and ensures clean print sharpness. This pigment is not designed for water-based systems—its optimized surface treatment and high specific surface (m²/g) are tailored for the solvent- and oil-based vehicle systems used in web and sheet-fed offset processes.
Which technical data points are verified for batch consistency of PIGMENT YELLOW 174?
Every batch of PIGMENT YELLOW 174 is tested for color strength, shade accuracy, dispersibility, and particle size distribution against ISO 9001 standards. Physical properties such as specific density (g/cm³), specific surface area (m²/g), and resistance to acid and alkali are recorded per batch. The pigment achieves heat stability up to specified °C and light fastness ratings as per internal standards, with low warping behavior measured for offset ink applications.
Why is PIGMENT YELLOW 174 preferred for heat-set offset inks over other yellow pigments?
PIGMENT YELLOW 174 (PY174) is preferred because its chemical structure (C₃₅H₃₂Cl₂N₆O₄) and physical properties ensure high viscosity and low warping in heat-set offset processes. The high tinctorial strength allows reduced pigment loading without sacrificing color density, while maintaining ink rheology for high-speed presses. Its resistance to alkali and acid reduces plate corrosion risks, making it a robust choice for commercial and publication printing where process color accuracy (CIE 12-66) is non-negotiable.
