FAQs About TS4020 Benchtop Spectrophotometers

The main instruments used to detect color are spectrophotometers and colorimeters (including photoelectric integrating colorimeters). 

Spectrophotometer: High-precision option. It analyzes the full visible light spectrum to measure color accurately. Suitable for complex scenarios like textured surfaces, special effect colors, or batch consistency checks in industries such as paint and coatings. 

Colorimeter (Photoelectric Integrating Colorimeter): Cost-effective and portable. It uses RGB filters to measure tristimulus values directly. Ideal for quick color difference detection in simple applications. Key Selection Tip Choose based on accuracy needs: use a spectrophotometer for high-precision color measurement, and a colorimeter for fast, basic color difference checks.


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.


Colorimeters or spectrophotometers are used to measure liquid color. They measure light coming through or reflecting off the liquid. Readings can be reported as Lab*, RGB, or absorbance units. So that objective color analysis can be used to control quality, or to measure chemical concentration.

For premier ink quality control (CMYK, spot colors, printing density, formulation & press-side QC), these 3nh spectrophotometers / spectrodensitometers stand above the rest:


1. YD5050 / YD5010 (Best for Printing & Ink Press QC)

  • 45/0 ring illumination, ISO 5-4 / ISO 13655 (M0/M1/M2/M3)

  • Measures density (Status T/E/A/I), dot gain, trap, print contrast

  • ΔE*ab ≤ 0.03, density ≤ 0.01D

  • Small apertures (Φ2/4/8mm) for fine print & ink dots

  • Ideal: packaging, label, gravure, flexo, CMYK/spot color control

    YD5050


2. TS8560 Benchtop (Lab Formulation & Highest Accuracy)

  • d/8° sphere, SCI/SCE, UV control

  • ΔE*ab ≤ 0.01 (repeatability), IIA ≤ 0.1

  • Multi-apertures (Φ3/8/15/25mm)

  • Best for: R&D, ink formulation, batch consistency, fluorescent inks

    TS8560_Benchtop_colorimeter


3. TS7700 Portable (Production & Field Matching)

  • d/8° (SCI/SCE), ΔE*ab ≤ 0.02

  • Fast, handheld, large Φ20mm aperture

  • Best for: press-side checks, warehouse incoming ink, on-site matching

4. YS6060 Benchtop (High-End Lab & Transmissive Inks)

  • 360–780nm, UV adjustable, dual CMOS

  • Reflection & transmission modes

  • Multi-aperture (Φ4/8/15/25.4mm)

  • Best for: high-precision lab R&D, transparent/fluorescent inks

    YS6060_Benchtop_colorimeter


Short Recommendation

  • Best press-side / print QC: YD5050

  • Top lab formulation: TS8560

  • Best portable production: TS7700

  • High-end lab R&D: YS6060

All ensure ultra-precise color, density & consistency for offset, flexo, gravure, screen-printing & packaging inks.


Many people might answer "with the human eye", but this is actually not comprehensive. The human eye cannot accurately distinguish the colors of similar objects. Furthermore, everyone's perception of color varies. Therefore, people have developed color measurement tools based on the CIE color system. 

Currently, there are two main types of commonly used colorimeters, as follows: 

Colorimeter - It is an ideal choice for quality control (QC) on production lines, used to detect color differences. 

Spectrophotometer - It is suitable for the development of color characteristics and color analysis in laboratories.
