The YE0117 is designed for the quick (mainly visual) appraisal of HDTV camera´s transmission characteristics. It consists of a gray background on which circles, gray scales, horizontal and vertical lines are positioned.

In the center of the test chart on a gray background (D=0.75; reflectance = 18%) a white circle with gray scales and resolution wedges is located. On both sides of this central circle four circles with resolution wedges are arranged.

The 16:9 format is marked by four arrows located on the horizontal and vertical central lines. In addition, four arrows located close to the circles on the upper and the bottom edge of the picture mark the 4:3 format. Thus the test chart can also be used for testing 4:3 cameras.

The white central circles shows four gray scales each of 11 steps. They increase in equal linear steps from D=0.15 to D=1.65 and are used for checking halftone rendition of HDTV cameras. Due to the white surrounding area the results may, however, be qualified.

All frequency values in the test chart are indicated in cph (cycles per height). In the central circle three resolution wedges with different frequencies are arranged vertically and horizontally. They reach from 100 to 250, from 200 to 500 and from 400 to 1000 cph. In addition, two resolution wedges angled in 45° generate frequencies of 200 to 500 cph.

In the middle of the test chart and on the left and right sides there are four squares with line rasters that are inclined at angles of 0, 45, 90 and 135°. They generate a frequency of 200 cph. Those line rasters which are inclined at angles of 45° and 135° generate a different frequency (141.4 cph) in horizontal and vertical direction (due to their inclination). The eight outer circles are arranged in such a way that they can be used both for 16:9 and 4:3 format. The larger ones show cross-shaped resolution wedges. The circular rings, which can also be used for checking geometry, are designed for marking the resolution in vertical and horizontal direction. Resolution is shown at 200, 500, 660, 725 and 800 cph.

The outer circles in the four corners have longer resolution wedges. They cross at 500 cph and have markings from 200 to 800 cph.

In the center of the test chart both in the gray and white area bar elements are arranged with a length of 1 (=half the picture-height), 2, 4, 8, 16, 32 and 64 cph. Left to right vertical gray scale there are five additional short bars with 100, 300, 500, 700 and 900 cph.

FAQs About  Other Charts

A powder coated surface is most commonly measured for thickness post curing using a digital coating thickness gauge. This method is non-destructive, helps verify coverage uniformity and meets quality control standards. A powder comb gauge is used to estimate thickness for a pre-cured coating.

3nh Spectrophotometers for Paint Formulation 

For paint formulation accuracy, the 3NH top spectrophotometers prioritize high spectral resolution, excellent repeatability, superior inter-instrument agreement (IIA), d/8° integrating sphere design, and compatibility with advanced formulation software. Below are the leading models

  1. 3nh TS8560 Premium Benchtop Spectrophotometer  (Lab & R&D – Highest Accuracy)

    High precision with d/8° integrating sphere, excellent repeatability and inter-instrument agreement.

Pairs seamlessly with Pecolor software for precise recipe calculation.

  2. Best for: High-end industrial coatings, R&D, and demanding formulation labs, High-volume paint labs, global color standardization

  3. 3nh TS7700 Portable Spectrophotometer

    Compact and easy to operate, supports SCI/SCE measurement. Perfect for on-site color matching, production line inspection and daily paint tinting control. Seamlessly connects to PeColor for on-the-go formulation, rugged, easy-to-use, designed for high-throughput retail environments.

  4. Best for: Retail paint stores, fast, accurate counter matching, On-site tinting, production line checks

  5. 3nh MS3008 Multi-angle Spectrophotometer

    Professional for metallic, pearlescent and special-effect paints. Captures angular color variation to meet high-end automotive and coating formulation requirements. Captures complex light behavior for perfect effect-paint matches.

  6. Best for: Automotive, specialty coatings


All these instruments deliver superior performance by measuring precise spectral data, which is the foundation for accurate, repeatable, and cost-saving paint formulation.

A colorimeter is a quick and inexpensive method to measure color and to control color in a material or solution. It is used to maintain color consistency during production and to check the chemical concentration. It also assists with the quality control of labs, food, textiles, and pharmaceuticals.


Compared to an analog model, digital gauges not only provide more accuracy, but also allow for greater repeatability and are easier to work with. Advanced digital gauges allow for features such as data storage and automatic calibration and statistical analysis. For these reasons, digital gauges are the preferred choice for professional applications.


In industrial production and quality control, color consistency is one of the core elements determining product quality. Whether it is the metallic paint for automobile coating, the dyeing effect of textile fabrics, or the ink matching in packaging and printing, subtle color deviations may lead to cost waste or damage to brand image.

The LAB color space defines colors with a three-dimensional model:

  1. Lightness (L): It indicates the lightness or darkness of a color, ranging from 0 (pure black) to 100 (pure white).

  2. Hue and Saturation (a and b):

    • The a-axis represents the red-green tendency, with positive values leaning towards red and negative values leaning towards green;

    • The b-axis represents the yellow-blue tendency, with positive values leaning towards yellow and negative values leaning towards blue.

It is a globally recognized standard and supported by most modern color measurement equipment. Color is quantitatively analyzed by measuring Lab values with instruments.
