Application of TS7600 Spectrophotometer in Color Detection in Printing and Packaging

Color difference refers to the difference between the color of a product and a standard sample. As the industry continues to evolve, color difference has become a focus of customer attention, a barrier to market competition, and a key branding issue for packaging and printing companies. However, this increasing customer demand for color difference is a double-edged sword for companies.

If the color difference is well controlled, it can be used to beat the competition. If it is not well controlled, it will also be subject to customer complaints, returns, and even be ruthlessly eliminated by the market.

Below we will describe the steps in detail:

Step 1: Prepare the sample to be tested;

Step 2: Turn on the TS7600 spectrophotometer and perform black and white calibration;

Step 3: After the black and white calibration is completed, press the “Print” button, first locate the measurement area with the image, align the standard sample to be measured with the test hole, be careful not to leak light to avoid affecting the test results, then press the “Test” button. After the “beep” sound, the measurement is completed and the test results can be viewed;

Step 4: After completing and saving the standard sample measurement, press the “Menu” key to enter the “Sample Measurement” interface for that standard sample. Align the sample with the test hole according to the standard sample measurement method and press the “Test” key to measure. After a “beep” sound, the color difference measurement is complete and the measurement result is obtained. Compare it with the standard sample result to see if it is qualified.

Based on the measurement results, customers can control color differences during the packaging and printing production process, greatly reducing time and labor costs.

TS7600 Spectrophotometer features

The TS7600 Spectrophotometer is a professional color measurement device designed for industrial quality control, with core features focusing on high accuracy, multi-scenario adaptability, and user-friendly operation.

1. Core Measurement Performance

• High-Precision Optical System: Adopts a double-beam optical structure and high-sensitivity CCD sensor, covering a wavelength range of 400–700 nm (visible light spectrum). This ensures accurate capture of subtle color differences, with a color difference repeatability (ΔE*) ≤ 0.02 (for standard white tiles under D65 light source), meeting strict industrial standards (e.g., plastics, coatings, textiles).
• Flexible Measurement Geometry: Supports both d/8° (diffuse illumination, 8° viewing angle) and 45°/0° (45° illumination, 0° viewing angle). The former is suitable for non-metallic materials (e.g., paints, plastics), while the latter is ideal for metallic or glossy surfaces (e.g., metal coatings, printed films), adapting to diverse material types.

2. Practical Functionality

• Multi-Light Source Simulation: Built-in standard light sources including D65 (daylight), D50 (printing standard), A (incandescent lamp), and F2/F7/F11 (fluorescent lamps). This allows users to simulate color performance under different real-world lighting conditions, avoiding color mismatch caused by lighting differences.
• On-Site & Off-Site Compatibility: Features a portable, lightweight design (typically ≤ 1.5 kg) with a rechargeable lithium battery (supporting 8+ hours of continuous use). It also supports offline data storage (up to 10,000 sets) and subsequent PC synchronization via USB/Bluetooth, enabling flexible use in factories or fieldwork.
• Intuitive Operation: Equipped with a 3.5-inch color touchscreen and simplified menu interface. It provides one-key measurement, automatic color difference calculation (ΔE/ΔL/Δa/Δb), and visual color comparison graphs, reducing the learning curve for operators.

3. Industry-Specific Adaptability

• Durable & Environmental Resistance: The outer shell uses wear-resistant ABS material, and the measuring port is equipped with a scratch-proof quartz glass window. It has an IP54 dustproof and waterproof rating, suitable for harsh industrial environments (e.g., workshops with dust or slight moisture).
• Broad Material Compatibility: Comes with interchangeable measuring apertures (e.g., 2 mm/4 mm/8 mm) to match small samples (e.g., electronic components) or large-area materials (e.g., textile fabrics). It also supports optional accessories like a powder sample holder or liquid sample cell, expanding use cases to powders and liquids.
