The YE111 flesh tone test chart is designed for evaluating the flesh tone rendition of electronic cameras. The picture shows the portraits of three women with ideal and critical flesh tones.

The picture areas marked with circles

The picture areas marked with circles have the following color coordinates in the CIE-L*a*b*-system:

  L* a* b*
woman left 75.27 19.45 27.46
woman middle 78.04 12.50 16.65
woman right 83.26 10.18 13.49
 

Utilization

The test transparency is designed for matching several color cameras to an approximately uniform color rendition of human flesh tones.

FAQs About  Other Charts

Spectrophotometers can only measure haze if it has haze measuring capabilities, as many measure color and transmittance.


Measurement Accuracy (dE/ΔE): The smaller the value, the higher the match between the color measured by the colorimeter instrument and human visual perception. Generally, dE < 1.0 is regarded as the industrial passing line, while dE < 0.5 falls into the high-precision level. 

Measurement Structure: D/8 (integrating sphere structure) is the universal standard, which includes two modes: SCI (Specular Component Included, with specular reflection light) and SCE (Specular Component Excluded, excluding specular reflection light). 45/0 (ring illumination) simulates the human eye's viewing angle and is more suitable for judging reflective materials. 

Repeatability: It refers to the difference in color results when measuring the same point multiple times. The equipment can achieve ΔE < 0.08, ensuring highly reliable measurement results. 

Illumination Source and Viewing Angle: It is recommended to choose the combination of CIE standard light source D65 (simulating daylight) and a 10° viewing angle. 

Application Scenario Requirements: It is necessary to clarify the purchase purpose (quality inspection? R&D? material evaluation?) and the usage environment (laboratory, workshop or field work?).


Pantone light boxes are mainly used for standardized color viewing and color consistency verification across multiple industries to ensure accurate color evaluation under uniform light conditions. Core Application Industries like Textile & Garment Industry, Printing & Packaging Industry, Paint, Ink & Coating Industry, Plastic & Electronic Product Industry, Cosmetics & Food Industry


A service is made up of tub replacement, light source recalibration, internal cleaning, verification of service and color certification retention so that all compliance color standards are retained. 


The LAB color space defines colors in a three-dimensional model: Lightness (L), red–green axis (a), and blue–yellow axis (b). It's a globally recognized standard supported by most modern color measuring devices. CIELAB is a standardized, device-independent system designed to map all visible colors that the human eye can perceive.

The LAB color space uses three values to define any color, each representing a specific dimension:


L (Lightness): Ranges from 0 to 100. It measures the brightness of the color, where 0 is pure black and 100 is pure white.
A (Red-Green Axis): Ranges from approximately -128 to +127. Positive values represent red tones, while negative values represent green tones.
B (Yellow-Blue Axis): Ranges from approximately -128 to +127. Positive values represent yellow tones, while negative values represent blue tones.


Keep light booths clean, maintain the light source lamps, readjust the calibrated light source, and ensure that dust and fingerprints do not settle on the viewing area.
