NJ-10-100A is designed for operational adjustment and control of TV cameras. It consists of circles permitting rough visual appraisal of scan linearity, grid lines serving the purpose of adjusting registration and wedges serving the purpose of resolution appraisal.

A grid structure consisting of 23 horizontal and 35 vertical lines is arranged on a white background. 3 grid lines each divide the outer 3 grid rows in the middle. The width of the grid lines is 0.15% of the picture width. The large circular line has a diameter of 83 1/3% of the picture height, the 5 small circular lines have a diameter of 25% of the picture height.

4 resolution wedges are arranged in the large circle at angles of 0°, 45°, 90°, and 135° corresponding to signal frequencies of 2-10 MHz. (The marking ends at 8 MHz and 600 lines).

UTILIZATION

  • The test chart is designed for operational adjustment and control of TV cameras.

FAQs About  Geometric Test Charts

Ambient light may affect the test results and must therefore be kept to a low level for accurate haze meter results. 


Inconsistent results from a haze meter can stem from issues like calibration, dusty haze meter optics, inadequate power supply, and improper measurement technique. If you have any questions, you can contact our Haze measurement experts


For premier ink quality control (CMYK, spot colors, printing density, formulation & press-side QC), these 3nh spectrophotometers / spectrodensitometers stand above the rest:


1. YD5050 / YD5010 (Best for Printing & Ink Press QC)

  • 45/0 ring illumination, ISO 5-4 / ISO 13655 (M0/M1/M2/M3)

  • Measures density (Status T/E/A/I), dot gain, trap, print contrast

  • ΔE*ab ≤ 0.03, density ≤ 0.01D

  • Small apertures (Φ2/4/8mm) for fine print & ink dots

  • Ideal: packaging, label, gravure, flexo, CMYK/spot color control

    YD5050


2. TS8560 Benchtop (Lab Formulation & Highest Accuracy)

  • d/8° sphere, SCI/SCE, UV control

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

  • Multi-apertures (Φ3/8/15/25mm)

  • Best for: R&D, ink formulation, batch consistency, fluorescent inks

    TS8560_Benchtop_colorimeter


3. TS7700 Portable (Production & Field Matching)

  • d/8° (SCI/SCE), ΔE*ab ≤ 0.02

  • Fast, handheld, large Φ20mm aperture

  • Best for: press-side checks, warehouse incoming ink, on-site matching

4. YS6060 Benchtop (High-End Lab & Transmissive Inks)

  • 360–780nm, UV adjustable, dual CMOS

  • Reflection & transmission modes

  • Multi-aperture (Φ4/8/15/25.4mm)

  • Best for: high-precision lab R&D, transparent/fluorescent inks

    YS6060_Benchtop_colorimeter


Short Recommendation

  • Best press-side / print QC: YD5050

  • Top lab formulation: TS8560

  • Best portable production: TS7700

  • High-end lab R&D: YS6060

All ensure ultra-precise color, density & consistency for offset, flexo, gravure, screen-printing & packaging inks.


Make sure the light sources are calibrated, keep extraneous light sources away, have the correct viewing angles, and handle the samples in a clean and uniform manner.


An inappropriate viewing angle may lead to reflections or color shifts in the light. The correct angle of 45 or 0 will provide the real color of the assessment without the distraction of glare.

Because of its unmatched precision, ease of use, adherence to global standards, and consistent long-term reliability.
