Image Quality Testing Solutions


As a global leader in image quality testing, we leverage our expertise in image quality testing, equipment, and knowledge to help companies across industries worldwide improve their imaging devices.

Standard camera testing typically covers multiple image quality metrics such as resolution, texture detail retention, noise, dynamic range, color accuracy, distortion, shading non-uniformity, and chromatic aberration. Camera systems often require comprehensive multi-dimensional evaluation.

Through the efforts of our R&D department and the introduction of high-precision production equipment, Threenh has gained the capability to customize various types of test charts. We can produce all kinds of transmission-type test charts (e.g., film charts) and reflection-type test charts according to clients’ specified drawings. Commonly used camera testing charts such as resolution charts, color bar charts, distortion test charts, grayscale charts, and dynamic range test charts can all be customized, significantly reducing costs for high-tech enterprises globally.

FAQs About  Test Charts

A colorimeter is sufficient for basic, routine color checks, while a spectrophotometer is needed for precise, comprehensive color analysis—here’s the clear breakdown:

When a Colorimeter is Sufficient

  1. Simple color matching needs: Ideal for checking if a sample matches a predefined standard (e.g., basic paint batches, plastic parts with solid colors).

  2. Consistent lighting conditions: Works well when measurements are done under fixed, standard light sources (no need to account for varied light effects).

  3. Cost-sensitive, high-volume tasks: Perfect for production lines requiring fast, low-cost color checks without advanced data analysis.

When to Use a Spectrophotometer

  1. Precise color quantification: Necessary for measuring Lab values (lightness, red-green, yellow-blue axes) or detecting subtle color deviations (critical for automotive coatings, high-end textiles).

  2. Complex color analysis: Required for metallic/pearlescent finishes, transparent materials, or samples with gloss/texture variations.

  3. Compliance and documentation: Essential when precise color data (spectral curves) is needed for quality audits, regulatory compliance, or brand color standardization.


The haze meter test assesses the degree of light scattering that occurs when light traverses a transparent or translucent material, producing a percentage that quantifies example or cloudiness.

Threenh colorimters are used across various industries to measure, analyze, and control color accuracy and consistency:

Food and Beverages: Monitor color quality in food products to meet industry standards.

Plastics and Polymers: Ensure color uniformity in plastic components (e.g., casings, buttons, panels) during manufacturing.

Chemicals and Pharmaceuticals,Cosmetics: Industry-specific accessories to attain the highest safety protocols, Ensure uniform color in pharmaceutical products for quality and brand recognition;Develop and match colors for cosmetics (e.g., lipsticks, creams, powders) and ensure batch consistency.

Textiles and Apparel: Monitor color consistency in fabrics during dyeing, printing, or finishing processes; ensure color consistency in fabrics and garments.

Building materials, Paints, and Coatings: Detect color deviations in coatings on metal, wood, or plastic surfaces (e.g., automotive paints, furniture finishes). Maintain color accuracy in building materials, paints, and coatings.

Printing and Packaging: Validate color accuracy in printed materials (e.g., brochures, labels, packaging) against design proofs, maintain consistency across different printing technologies.

By addressing color-related quality control challenges, 3NH colorimeters help industries maintain brand consistency, meet regulatory standards, and enhance customer satisfaction.


The CCC is much like the CAC yet it frequently has advanced programmable lighting, sophisticated electronic control systems that allow for light source switching, and advanced visual testing.


Common sources like D65, TL84, and CWF mimic daylight, store, home, and fluorescent lighting, and are used to provide conditions for dependable color comparison.


Light booths and color matching are essential for the textiles, printing, automotive, plastics, cosmetics, and coatings industries. These fields rely on tight color alignment to protect brand value and meet global quality demands for color.
