Tokyo (February 19, 2019) - Konica Minolta, Inc. (Konica Minolta) today announced that the company will launch the new CM-26dG series of portable spectrophotometers for high-precision color measurement, including the mid-range model CM-26d and cost-effective model CM-25d to be introduced in March 2019 plus the advanced flagship model CM-26dG for simultaneous color and gloss measurements which will be introduced in Autumn 2019.
The CM-26dG, CM-26d, and CM-25d are new models being introduced as successors to the CM-2600d and CM-2500d spectrophotometers used by many customers in the automobile and IT industries. These products are used mainly at production sites that manufacture interior parts for automobiles and exterior parts for smartphones and tablets, 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 (CM-26dG only)
The CM-26dG is a “two-in-one” type of spectrophotometer that can simultaneously measure color and gloss, with a compact body weighing just 660 g. This helps increase efficiency and reduce manpower when measuring large quantities of samples, significantly improving the existing inspection process of customers.
2. 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 and CM-26d, an improvement of about 40% from previous models. (Within ΔE 0.2 for the CM-25d.)
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.
3. 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 and CM-26d can switch between Ø8mm and Ø3mm measurement areas (the CM-25d has a fixed Ø8mm measurement area) for measuring parts of different sizes. All models are also 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.
4. Faster measurements for increased task efficiency and improved durability for reduced downtime
For products produced in bulk such as smartphones, 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.
