Konica Minolta to Release New Portable Spectrophotometer to Improve Productivity, the CM-26dG Capable of Simultaneously Measuring Color and Gloss

Ramsey N.J. (October 15, 2019) – Konica Minolta Sensing Americas, Inc. (Konica Minolta) today announced that the company will launch the new CM-26dG portable spectrophotometers for high-precision color and gloss measurement.

The CM-26dG has already won awards, most notably, the the Good Design Award 2019 by the Japan Institute of Design Promotion (JDP) for its advanced design created to minimize user stress and maximize operability and ease of handling.

The CM-26dG, is an enhancement of the CM-26d introduced last spring, and has already become an intergral part of supply chains for many customers in the automotive, plastic, and ICT industries.

The CM-CT1 Configuration Tool software available as a free download allows users to create/write instrument settings as well as compile it into a file and share it within its supply chain to ensure consistent instrument settings, helping to increase efficiency and reduce manpower in customer operations and enabling digital color data management*1 across increasingly globalized supply chains.



Values offered by CM-26dG Series

  1. Improving the inspection process by quickly measuring color and gloss at the same time

The CM-26dG is a “two-in-one” type of spectrophotometer can simultaneously measure color and gloss, with a compact body weighing just 660g. This helps increase efficiency and reduce manpower when measuring large quantities of samples, significantly improving the existing inspection process of customers.


  1. Achieving outstanding quality control with the industry’s top level of measurement accuracy

The CM-26dG series provides extremely high inter-instrument agreement, with very little variation among units. This enables these instruments to be used for quality control across the supply chain, from component part manufacturers to those of finished products. The inter-instrument agreement of the chromaticity value (average for 12 BCRA color tiles) is within ΔE 0.12 for the CM-26dG, an improvement of about 40% from previous models.

This superb measurement accuracy enables digital color data management, which is color management based solely on colorimetric data without having to use color reference plates (which are troublesome to prepare and require strict control) for each site. These new instruments thus help customers attain exceptional quality control across their supply chains worldwide.

  1. Helping improve operator productivity with high usability

The Job function*2 enables measurement instructions (including photographs) for routine tasks to be registered in the instrument, helping to improve productivity by promoting work uniformity regardless of differences in operator skills.

The CM-26dG can switch between Ø8mm and Ø3mm measurement areas for different area size of samples. And is equipped with a viewfinder for accurate positioning on patterned subjects or small parts, and instrument surfaces which come in contact with the measurement subject are designed to minimize subject damage.

  1. Faster measurements for increased task efficiency and improved durability for reduced downtime

For products produced in bulk such as ICT products, thousands of quality inspections may be conducted per day, requiring short measurement times and measurement intervals together with high instrument durability. The CM-26dG series fulfills both of these requirements. Even when measuring both color and gloss with the CM-26dG, measurement time is only about 1 second and measurements can be taken approximately every two seconds. In addition, durability in terms of measurement cycles has been significantly improved compared to previous models. The improved inspection speed and durability increase work efficiency and reduce downtime.
