How Is a Custom Color Created? Inside KCI’s Color Masterbatch Development Process

From color references and resin samples to mass production, discover the expertise behind successful color masterbatch development.

When customers come to KCI Master, they rarely bring only a color.

Sometimes it is a color reference card. Sometimes it is a competitor’s product sample. In other cases, it may simply be an early-stage product concept.

Our job is not just to reproduce a color.

More importantly, we help customers develop products efficiently while reducing the risks that may arise during future production.

This is why, at the beginning of every custom color masterbatch project, we focus on much more than the color itself.


Why Custom Color Masterbatch Development Is About More Than Color

In plastic product development, color performance is influenced by many factors, including material systems, processing methods, product design, application environments, and regulatory requirements.

Even the same target color can appear different when used with different materials or manufacturing processes.

Therefore, successful color matching is not simply about making colors look similar. It is about ensuring color consistency under real production conditions.


Step 1 | Understanding the Product Is More Important Than Understanding the Color

Many customers begin by asking:

“Can you make this color?”

In reality, KCI often starts with a different question:

“What product will this color be used for?”

The same color may face completely different challenges depending on its final application.

Different Applications Require Different Formulations

  • Outdoor furniture requires weather resistance and UV protection
  • Automotive components require heat stability
  • Home appliance housings require long-term color consistency
  • Food packaging must comply with regulatory requirements
  • PCR recycled materials may present challenges due to unstable base colors

By understanding the final product and application environment, KCI can help customers identify potential risks before they become costly production issues.

In many cases, a simple piece of application information can prevent extensive redesign, retesting, and production delays.


Step 2 | Providing Resin Samples Can Significantly Reduce Development Time

In addition to product information, we strongly recommend that customers provide the actual resin or raw material used in production.

The reason is simple: color performance depends not only on the color masterbatch itself, but also on the base material.

Even when using the same formulation, different materials, resin grades, or recycled material systems may produce different visual results.

Base Materials Can Affect:

  • Color difference
  • Gloss level
  • Transparency
  • Surface texture
  • Overall visual appearance

When we test colors using the customer’s actual production material, the results are much closer to future production conditions.

This approach improves color matching accuracy while significantly reducing the time and cost associated with repeated sampling, testing, and validation.

For many projects, providing resin samples is one of the most effective ways to accelerate product development.


Step 3 | Laboratory Color Matching and Sample Development

Once requirements are confirmed, KCI’s technical team begins formulation design and laboratory color matching.

Color development is not simply about matching visual appearance. It also involves evaluating pigment dispersion, processing stability, and final product performance.

Key Evaluation Factors Include:

  • Color difference control
  • Pigment dispersion quality
  • Heat resistance
  • Processing stability
  • Final appearance performance

Every custom color masterbatch project represents a combination of material science, manufacturing experience, and customer requirements.


Step 4 | Production Validation Before Mass Manufacturing

After samples are approved, customers typically conduct actual processing trials.

The purpose of this stage is to verify that laboratory results can be successfully transferred to real production environments.

Validation Priorities Include:

  • Final product color accuracy
  • Processing compatibility
  • Appearance consistency
  • Production stability

This validation process helps reduce risks related to color variation, rework, and production quality issues before full-scale manufacturing begins.


Step 5 | Stable Mass Production and Quality Control

The real challenge begins when mass production starts.

A successful custom color masterbatch solution must maintain consistent performance not only during development but throughout ongoing production.

KCI continuously monitors raw materials, formulations, manufacturing conditions, and quality control standards to ensure product consistency.

Key Quality Control Areas Include:

  • Raw material quality
  • Pigment batch consistency
  • Production condition control
  • Color difference management
  • Quality inspection standards

KCI’s Perspective: Color Is More Than Color

For consumers, color is a visual experience.

For brands, color represents identity.

For manufacturers, color reflects product quality, consistency, and competitiveness.

That is why KCI believes we do more than manufacture color masterbatch.

We help customers shorten development cycles, reduce testing costs, and minimize production risks through material expertise and technical support.

This is the true value behind every successful color.


Frequently Asked Questions (FAQ)

Q1: What information is needed for custom color masterbatch development?

We recommend providing the target color reference, actual production material, product application, processing method, regulatory requirements, and expected production conditions. More complete information generally leads to higher development efficiency and better color accuracy.

Q2: Why are actual resin samples important?

Different materials, resin grades, and recycled material systems can affect final color appearance. Testing with actual production materials helps achieve results that are much closer to real manufacturing conditions.

Q3: Can KCI develop colors for PCR recycled materials?

Yes. However, PCR materials often have greater variability in base color and consistency. Using actual production material for testing is highly recommended.

Q4: How long does custom color development take?

Development time depends on color complexity, material systems, functional requirements, and testing conditions. Providing complete project information at the beginning can help accelerate development.

Q5: Does custom color masterbatch only provide color?

No. In addition to color matching, KCI can integrate UV resistance, anti-static performance, weather resistance, flame retardancy, and other functional requirements into customized formulations.
