The  Spilled Coins chart (a variant of the Dead Leaves chart) for measuring texture sharpness has several advantages over older Dead Leaves charts. Key features:

  • The Scattered Coins pattern in the central region is almost perfectly scale-invariant (unlike conventional dead leaves charts), enhancing the accuracy and robustness of MTF measurements so they correlate well with other methods (such as the slanted-edge) for RAW images (which have no nonuniform or nonlinear processing).
  • Maximum contrast range is 3:1, as called for in the CPIQ Phase 3 draft Texture Blur Metric draft specification.
  • It is more uniform, i.e., is more shift-invariant than other Dead Leaves charts.
  • It contains slanted edges (2:1 and 4:1 contrast) for convenient comparisons with the dead leaves pattern.
  • The gray area to the left and right of the dead leaves pattern has the same mean density as the dead leaves pattern, allowing it to be used for effective noise PSD removal using the McElvain et. al. technique.
  • Registration marks and 16 grayscale patches are included. The linear levels used to create the grayscale patches are 0 through 255 in steps of 17 (same as the Siemens Star chart in the draft of the upcoming ISO 12233 standard).
  • Imatest Spilled Coins equivalent of the Image Engineering TE-265 referenced in the Skype spec is the Large, Matte ISC0024

FAQs About  Texture Test Charts

A coating thickness gauge measures coating thickness. It measures coating thickness using three different principles: magnetic induction, eddy current, or ultrasonic. Depending on the coating type and the coating's substrate material, the appropriate principle is selected. For industrial and laboratory use, most of these units deliver accurate, non-invasive readings.


In a Pantone light box, the tubes last around 2000 to 3000 hours, after which the brightness and color should be assessed for replacement.

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.

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


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

    3nh TS7700 

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.


D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries.
