New CM-36dG Series Benchtop Spectrophotometers for High-accuracy Color Management, Including Two Models that Offer Simultaneous Measurement of Color and Gloss
Contributing to DX of supply chain globalization
Ramsey (January 13, 2021) – Konica Minolta Sensing Americas, Inc. (Konica Minolta) today announced that the company will launch the new CM-36dG series of benchtop spectrophotometers, including the CM-36dG horizontal-format and CM-36dGV vertical-format models, both of which offer simultaneous measurement of color and gloss, and the CM-36d entry-level model for reflectance color measurements in February 2021.
The CM-36dG, CM-36dGV, and CM-36d are the successor models to the CM-3600A and CM-3610A benchtop spectrophotometers that have been widely used by material suppliers in the automotive and IT equipment fields. These instruments are targeted mainly at color-matching and quality control applications for paint, plastic, textile, etc. material suppliers, where simultaneous measurement of color and gloss*1 will increase the efficiency of inspection processes and high measurement accuracy enables outstanding quality control. In addition, they are equipped with a function that compensates for slight shifts in measured values due to ambient temperature changes, etc. to offer high stability and reliability. Measurement operation usability has also been greatly improved over the previous models which will lead to increased operator productivity.
With the Covid-19 making it difficult for people to travel and the continuing globalization of supply chains, digitalization and IT usage in production areas are now accelerating. By converting color and gloss information into digital data with high accuracy, these new instruments contribute to the digital transformation (DX) of manufacturing by realizing quality control without relying on target samples or the eyes of skilled workers.

Value provided by CM-36dG Series
- Simultaneous measurement of color and gloss for improved inspection processes
The CM-36dG and CM-36dGV are two-in-one instruments that measure color and gloss simultaneously. For paint color matching, measuring both color (spectral reflectance) and gloss increases the parameters for color-matching calculations, contributing to improved quality. For quality control of plastics, measuring both color (material color) and gloss (surface conditions) realizes high-level quality evaluation and improved work efficiency.
- High measurement accuracy for outstanding quality control
With the CM-36dG and CM-36dGV, differences in measurement values between instruments are exceedingly small (inter-instrument agreement is exceedingly high), so when these instruments are used consistently from suppliers through finished product maker, higher inspection process efficiency can be expected. Colorimetric inter-instrument agreement is within ΔE*ab 0.12 (average for 12 BCRA tiles), a 20% improvement compared to previous models, and gloss inter-instrument agreement is also the same or better than the performance of gloss-only instruments. This enables more efficient work in the supply chain when using multiple instruments or instruments in several locations.
In addition, since measured value differences with previous models are also kept exceedingly small, previous data can continue to be used as is, minimizing the work involved when switching models (for SCI data only*2).
*2 SCI: Specular Component Included. An illumination/viewing method in which the sample is diffusely illuminated and the measured light includes specularly reflected light.
- Optional Wavelength compensation function for high stability
CM-36dG Series instruments can be equipped with a WAA (Wavelength Analysis & Adjustment) function*3 which compensates for slight shifts in measurement values due to external factors such as ambient temperature changes, etc. Together with annual calibration and maintenance, it can help minimize problems for stable operation.
*3 WAA license required
【Concept of how accuracy is maintained by WAA】
- High usability for improved operator productivity
CM-36dG Series have several features to help improve worker productivity.
The sample viewing function*4 uses an integrated camera to provide a view of the sample from inside the integrating sphere for accurate positioning of measurement subjects. Plus, a status panel shows the measurement status and condition settings to reduce operator error, and a measuring button lets the operator take measurements without having to switch back to the computer for improved work efficiency. Plus, the transmittance chamber opens widely to enable measurements of even large sheets or panels without having to cut off a sample. And 4 measurement areas (3 on CM-36d) are provided for flexibility in choosing the appropriate area for the measurement subject.
*4 Software such as Konica Minolta SpectraMagic NX Ver. 3.2 or later required.
Three models are being offered: the horizontal-format full-featured CM-36dG, the CM-36dGV with the same features as the CM-36dG in a vertical format for easier textile or paper measurements, and the CM-36d with basic features for lower introduction cost.
