The YE0175 is designed for measurement of the disturbance caused by the video level in black areas to the right of or below the areas. Horizontal white lines are positioned on a black background.

Definition of streaking measurements

Measurement of the disturbance caused by the video level in black areas to the right of or below the areas.The disturbance is characterized by measuring the duration of the delay before the video level corresponding to the normal video level of the black is restored.

Measuring equipment

Video level meter; B/W monitor, oscilloscope, low-pass filter: 500 KHz

Measurement conditions

The chart illumination must be adjusted so that the white bars give a signal of 100% with average iris setting.

Gain: 0dB

Gamma corrector: OFF

Contour corrector: OFF

Knee corrector: OFF

Pedestal = 5% of nominal video level (= 35 mV)

FAQs About  Other Charts

Because color perception depends on the following factors: 

Light source - For example, incandescent lamps emit orange light, while fluorescent lamps emit cool white light. Therefore, placing an object near different light sources will result in different perceived colors. 

Observed object - Different types of objects affect color perception differently. Examples include opaque objects, translucent objects, and transparent objects. 

Observer's position - Each observer will describe colors differently based on the position of their eyes. 

Different backgrounds - An object's color will appear duller against a light-colored background than against a dark-colored background. Different directions of light reflection from the object - Light reflected from different directions creates different color perceptions. This is particularly noticeable with metallic objects.

Different directions of light reflection from the object - Light reflected from different directions creates different color perceptions. This is particularly noticeable with metallic objects.

Gloss level is not given out in percentage but in gloss units (GU). In practice, however, 100 GU is considered 100 percent reflective. To contrast visually, the 20-40 GU is a low-gloss surface, and 85 or more is almost 100 percent mirror-like reflection.


Testing metamerism helps to identify color matches that look the same but are different in different lighting. This helps in ensuring that materials are of the same quality in all light settings.


A spectrophotometer measures the full visible color spectrum (typically 400–700 nm). It offers significantly higher precision and enables detailed evaluations – including spectral curves, ΔE values, and color distance measurements. It is the preferred choice for demanding applications in labs or color development environments. learn more..

The core difference between a colorimeter and a spectrophotometer lies in their light measurement methods. A colorimeter measures color values based on the tristimulus method (e.g. LAB or RGB) and compares the sample to a reference. It's ideal for quick, repeatable measurements under consistent conditions – such as in production or incoming goods control.

Flickering lamps, color shifts, and uneven lighting are common faults, which can be corrected by changing the tubes, cleaning the interiors, and re calibrating the light system.

 A gloss meter measures the amount of light reflected from a surface at a specific angle. It's commonly used to assess surface finishes such as paint, coatings, plastics, and paper for consistency, quality control, and visual appearance evaluation.
