The YE084 is designed for the evaluation of the halftone reproduction of an electronic camera. Two 11-graduated counter current gray scales are arranged on a gray background (D≈0.65), the gray scales being graduated linear. Related to the densities of the gray scales: gamma = 1. The contrast range of the gray scales is 40:1.

Format selectable
Aspect ratio 4:3

The values of the 11-graduated gray scales are the follows:

 
Step Density Reflectance in %
1 0.05 89
2 0.10 80
3 0.14 72
4 0.20 63
5 0.26 54
6 0.34 45
7 0.43 37
8 0.55 28
9 0.71 19
10 0.96 11
11 1.65 2

The density of the white filed between the gray scales is D = 0.05 (reflectance = 89%).

FAQs About  Grayscale Charts

Gloss level is the extent of reflectance of light on a surface. It measures the shininess or dullness of a finish, from flat or matte to high gloss. It is important in aesthetic, functional, and quality control applications.


Light should be projected through the sample to measure haze, then assess the scattered light with an integrating sphere and sensors.  The haze percentage is ascertained by the scattering light to the total transmitted light.

For pharmaceutical tablet color accuracy & compliance (USP/EP/ICH/FDA), these 3nh spectrophotometers deliver superior precision:

1. TS8560 Benchtop (Lab/R&D – Highest Precision)

  • d/8° integrating sphere, SCI/SCE dual mode

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

  • Small apertures (Φ3mm/Φ8mm) ideal for tablets

  • Auto positioning, temp/humidity compensation

  • 21 CFR Part 11 software for audit trails

  • Best for: R&D, formulation, strict QC, coated tablets3nh TS8560 

2. TS8503 Benchtop (Mid-High Accuracy)

  • d/8°, dual CMOS sensor

  • ΔE*ab ≤ 0.018, IIA ≤ 0.24

  • Multi-aperture, camera view locating

  • Stable for batch-to-batch tablet consistency

3. ST70 Portable (Production/Field)

  • d/8° (SCI/SCE), ΔE*ab ≤ 0.02

  • Handheld, fast, non-destructive

  • Best for: line checks, incoming materials, small labs

4. NS800 (Cost-Effective QC)

  • 45/0 geometry, ΔE*ab ≤ 0.04

  • Rugged, touchscreen, easy QC

  • Suitable for uniform, uncoated tablets

Short Recommendation

  • Top lab accuracy: TS8560

  • Best value benchtop: TS8503

  • Portable production: ST70

  • Economical QC: NS800

All meet pharmaceutical standards for tablet color uniformity, coating consistency, and stability testing.


Depending on the scale of the manufacturer, its matte, low-sheen finish can be called gloss level 3. Overall, gloss levels in certain standards go between 1 (flat) to 7 (high gloss). Level 3 is considered low-gloss or satin-like.


Gloss is the general reflectivity of a surface, which encompasses a variety of degrees. One particular type of finish is high gloss, which has the maximum shine and reflectance. It increases the richness but emphasizes flaws as compared to satin or matte.


A spectrophotometer and colorimeter are certain instruments used by scientists to measure color by quantifying reflected or transmitted light. The results are presented in color spaces, such as L*a*b*, RGB, or XYZ. This enables the accuracy of comparison and tracking of the changes in color in chemical or material research.
