Details

This 15-patch grayscale step chart has 12 of the patches in a somewhat elliptical arrangement on the periphery and three in an inside row. Nominal patch densities are 0.1, 0.19, 0.3, 0.41, 0.53, 0.66, 0.81, 0.97, 1.17, 1.39, 1.66, and 2.0 for the 12 peripheral patches and 0.77, 0.90, 1.05 for the three central patches. The relatively large patches are especially good for measuring noise. Supported by the Imatest Stepchart, Multicharts, and ColorTest modules. 

The standard size has an active area of 11.4x17.1 inches (290x434 mm),printed on 12x18 inch (305x457 mm) luster (semigloss) inkjet media.

FAQs About  ISO Test 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.

Now our testing machines have been sold to more than 80 countries, like USA, Canada, Russia,UK, Italy, Germany, European , India, Pakistan, Philippine, Singapore, Malaysia,Thailand , Vietnam, Korea,Saudi Arabia,Brazil...and so on. We sell to the global market.

With centers in 20 countries, including India, Japan, USA, Germany, Singapore, China, South Korea, and Taiwan, Threenh Technology’ s service network aims to provide customers with convenient access to service globally. With over 1 million measuring instruments sold, our expertise is our greatest asset, enabling us to work with our customers on solutions to complex measurement challenges.

Smooth and uniform surfaces with a large amount of reflected light directly result in high gloss. Some of the factors are the smoothness of the surface, the type of paint that is being used, the thickness of the coating, and curing. The lesser the surface irregularities, the greater the gloss.


Calibrating a colorimeter before testing is critical for accurate, reliable color data—counteracting instrument drift, environmental interference, and component wear to ensure measurements reflect true sample colors. It guarantees compliance with industry standards, eliminates costly rework from flawed data, maintains brand consistency across batches/locations, and ensures data comparability with clients or regulators.

Calibrating a colorimeter before use is primarily to ensure the accuracy of measurement data and compensate for errors caused by the aging of internal components (such as light sources and phototubes) or environmental changes.

Below are the specific reasons: 

  1. Compensation for Component Aging and Environmental Influences

  2. Compensation for Environmental Factors

  3. Standardization of Measurement Baselines

  4. Operational Specification Requirements

3nh colorimeters are designed for immediate measurement upon startup. However, calibration (via black-white correction) is mandatory for the first use, sudden environmental changes, or abnormal data to restore measurement accuracy.

At most of time, we have Spectrophotometer stock in the factory. Generally it is 1-3 working days after the payment confirmed. After shipped, we will email you the tracking number. You can check the shipping status of your order on the website. If you are in urgent need, we can consider making special arrangement for you.

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.
