Color Masterbatch FAQ: Color Matching, RAL, Pantone, and Consistency

Color Masterbatch Questions Answered

Color masterbatch brings precise, repeatable color to plastic products. This FAQ covers color matching, RAL and Pantone systems, and batch-to-batch consistency.

What is color masterbatch?

Color masterbatch is a concentrated dispersion of organic or inorganic pigments in a polymer carrier, let down into base resin during processing to produce a specific color.

Can you match any color?

Yes. MHK Color maintains a 30,000+ formulation database and matches RAL, Pantone, and custom colors. Most colors can be matched within 24 hours with a free sample.

What is the difference between RAL and Pantone?

RAL and Pantone are two color standard systems. RAL is common in Europe (especially for industrial products), while Pantone is widely used in design and branding. We match both, plus custom colors.

How is color consistency measured?

Color consistency is measured using spectrophotometry in the CIELAB color space, expressed as Delta E (ΔE). MHK Color maintains ΔE < 1.0 batch-to-batch consistency.

What is Delta E?

Delta E is a numerical measure of color difference. ΔE < 1.0 is barely perceptible and is the standard for masterbatch consistency. ΔE < 0.5 is imperceptible.

Why does my color shift between batches?

Color shift can come from raw material variation, inconsistent dosing, processing temperature changes, or an unstable masterbatch formulation. Working with a supplier that maintains strict batch control and Delta E < 1.0 prevents this.

What pigments are used?

Both organic pigments (bright, saturated colors) and inorganic pigments (durable, opaque colors) are used, often combined to achieve the target shade with the right durability and cost.

How fast can I get a color match?

Free color matching with a physical sample within 24 hours for most standard colors. Complex or custom colors may take 3–7 days.

Do you offer food-grade or medical-grade color masterbatch?

Yes. We offer FDA/EU 10/2011 food-contact grades and USP Class VI medical grades using compliant pigments.

What information do I need to provide for color matching?

Provide your target color (RAL/Pantone code or physical sample), base resin, processing method, and application. This lets us match the color accurately and select compatible pigments.

Conclusion

Color masterbatch delivers precise, consistent color when backed by a large formulation database and rigorous color measurement. MHK Color offers free color matching, 24-hour samples, and ΔE < 1.0 consistency. Send us your target color for a match.
