At Mine Colours, colour matching is more than a technical procedure. It is a collaborative process built on communication, precision, and a clear understanding of each customer’s production requirements.
Every project begins with the customer’s needs. We first review the target colour sample, Pantone reference, RAL code, or other colour standard provided by the customer. At the same time, we collect key technical details such as the carrier resin, end-use application, processing method, dosage requirements, regulatory needs, and any additional performance expectations.
This early collaboration allows our team to develop a colour solution that is not only visually accurate, but also suitable for the customer’s real production environment.
Step 1: Understanding the Requirement
Before formulation begins, our technical team evaluates the customer’s full requirement. Colour performance can be affected by resin type, wall thickness, processing temperature, opacity, additive package, and final application. That is why we take the time to understand the complete picture before developing a masterbatch solution.
Whether the customer is working with PE, PP, PET, PS, PA, or engineering polymers, our process is designed to match the colour accurately while supporting production consistency.
Step 2: Laboratory Analysis and Colour Matching
Once the target is received, our colour laboratory analyzes the sample using state-of-the-art photospectrometer technology. This allows us to measure the target colour with precision and develop a formulation based on both instrument data and practical processing experience.
Our colour matching team brings more than 100 years of combined experience in plastics and colour development. By combining advanced measurement tools with deep technical know-how, we are able to match colours with sub-1.0 ΔE accuracy.
Step 3: Sample Preparation
After the colour is matched, we move into sample preparation. Our lab-scale extruders allow us to quickly produce trial samples for customer review and approval. These samples are prepared under controlled conditions to closely represent the customer’s production requirements.
This stage gives customers the confidence to evaluate colour performance before moving into full-scale production.
Step 4: Quality Control at Every Stage
Quality is built into every stage of our process. Each colour goes through three separate internal quality control procedures during development and production. These checks help verify colour accuracy, dispersion, processing behaviour, and final product consistency.
By maintaining strict internal controls, we reduce production risk and help customers achieve repeatable results from batch to batch.
Step 5: Customer Approval and Production Standardization
Once the customer approves the colour, the formulation is assigned its own barcode and becomes a standard formulation in our system. This allows us to reproduce the same colour accurately for future orders while maintaining full traceability.
Every approved formulation is documented, controlled, and connected to our internal production standards.
Step 6: Sample Archiving for Long-Term Consistency
To support long-term colour consistency, Mine Colours archives approved samples for up to five years. This allows our team to reference historical samples when needed and helps customers maintain continuity across repeat orders, product lines, and production cycles.
A Process Built Around Precision and Partnership
At Mine Colours, our process is designed to give customers confidence from the first colour sample to full-scale production. Through technical communication, advanced laboratory analysis, experienced colour matching, strict quality control, and long-term sample archiving, we deliver colour solutions that manufacturers can depend on.
Our goal is simple: to make colour development faster, more accurate, and more reliable for every customer we serve.
