Press Release: New Konica Minolta Benchtop Spectrophotometer CM-36dG Series

KONICA MINOLTA BENCHTOP SPECTROPHOTOMETER CM-36dG SERIES 

For High-Accuracy Color Management and Digital Transformation Of Global Supply Chain

Singapore, 14th January 2021

Konica Minolta Sensing Singapore Pte Ltd is pleased to announce the launch of the new benchtop spectrophotometer CM-36dG series in February 2021.

The new series includes the horizontal-format Spectrophotometer CM-36dG and vertical-format Spectrophotometer CM-36dGV, both of which offer simultaneous measurement of color and gloss, and the entry-level model Spectrophotometer CM-36d for reflectance color measurements.

Successor to the benchtop Spectrophotometers CM-3600A and CM-3610A that are widely used by material suppliers in the automotive and IT equipment fields, the new Spectrophotometer CM-36dG series is ideal for color-matching and quality control applications for paint, plastic, textile, etc., and material suppliers. The new CM-36dG series offers simultaneous measurement of color and gloss*1 for inspection processes efficiency and high measurement accuracy for outstanding quality control.

The new CM-36dG series offers high stability and reliability with the WAA (Wavelength Analysis & Adjustment) function that compensates for slight shifts in measured values due to external influences like ambient temperature changes. Measurement operation usability has also significantly improved to help increase operator productivity.

With the coronavirus and the globalization of supply chains, digitalization in production areas is accelerating. The new Spectrophotometer CM-36dG series can convert color and gloss information into digital data with high accuracy, enabling the digital transformation (DX) of manufacturing by realizing quality control without relying on target samples or the eyes of skilled workers.

Simultaneous Measurement Of Color And Gloss For Improved Inspection Processes Efficiency

The CM-36dG and CM-36dGV are both two-in-one spectrophotometers that offers simultaneous color and gloss measurement. For color matching of paint, measuring both color (spectral reflectance) and gloss increases the parameters for color-matching calculations and help improve quality. For quality control of plastics, high-level quality evaluation and improved work efficiency can be achieved by measuring both the color (material color) and the gloss (surface conditions).

High Measurement Accuracy For Excellent Quality Control

Both the Spectrophotometer CM-36dG and Spectrophotometer CM-36dGV offers extremely tight inter-instrument agreement. The colorimetric inter-instrument agreement for both instruments are within ΔE*ab 0.12 (average for 12 BCRA tiles), a 20% improvement compared to their predecessor, with their gloss inter-instrument agreement matches or better the performance of gloss-only instruments.

With such tight inter-instrument agreement, exceedingly small differences in measurement data between instruments can be expected. It enables a more consistent measurement result, efficiently, within the supply chain, from suppliers to finished product maker, when using multiple instruments or instruments in several locations.

Additionally, measurement data differences against their predecessor are also kept exceedingly small. Older data from their predecessor can continue to be used as it is, minimizing the work needed when switching models (for SCI data only*2).

High Stability Through Wavelength Compensation Function

The WAA*3 function compensates for slight shifts in measurement data due to external factors (e.g., ambient temperature changes, etc.). Together with annual calibration and maintenance, stable operation, with minimum problems, can be expected.

High Usability For Improved Operator Productivity

The new Spectrophotometer 36dG series comes with the sample viewing function*4. It uses an integrated camera that provides a view of the sample within the integrating sphere, allowing accurate and easy positioning of the measurement sample.

The CM-36dG series features a status panel that displays both the measurement status and condition settings to help minimize operator error. The measuring button is also located at the status panel for improved work efficiency, allowing the operator to take measurements without switching back to the computer.

Also, the 36dG series comes with a large and wide transmittance chamber that allows easy measurements of large sheets or panels without needing to cut them. 4 different measurement areas (3 different measurement areas for Spectrophotometer CM-36d) are available to provide flexibility for different measurement needs.
