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

  1. 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.

  1. 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.

  1. 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】

 

  1. 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.

Introduction of a new assessment of measurement technology TAMS (Total Appearance Measurement System)

Ramsey N.J. (October 15, 2020) Rhopoint Instruments Ltd. announces that Volkswagen AG has introduced a new assessment measurement technique for the surfaces of painted car bodies. The Rhopoint TAMS™ (Total Appearance Measurement System) technology was developed as part of an innovation project and is now about to be introduced into series production.
The Rhopoint TAMS™ technology is the result of a six-year joint development project between Rhopoint Instruments Ltd., Audi AG and Volkswagen AG and offers the car manufacturer improved parameters for controlling the appearance quality of painted car bodies and painted vehicle parts.

As a result of the successful test phase in the production lines, Rhopoint TAMS™ is a newly specified technology of Volkswagen AG and has been included in the technical delivery conditions and quality test specifications.

Rhopoint TAMS™ measures what you see

TAMSWith the current methodology for measuring and controlling the appearance of painted surfaces, the biggest challenge is to correlate the measured results with the visual assessment of the quality inspectors or, in other words, "what you measure is not always what you see". Rhopoint Instruments Ltd. and the specialist departments of Audi AG and Volkswagen AG have jointly developed a new methodology and technology to meet this challenge. The result is the Rhopoint TAMS™, a device that uses the technology of image projection and image analysis to imitate visual perception. Stripe images projected onto a surface are captured with a dual-focus camera, while established optical analysis techniques (e.g. optical transfer functions) are used to calculate indices that describe surface properties in the same way as the human eye.

The result is a much higher agreement with visual perception, which is essential for quality control in production. The Rhopoint TAMS™ "Quality" (Q) value allows pass/fail decisions to be applied based on this final manufacturing criterion, while the "Harmony" (H) value ensures that adjacent body parts can be perceived as optically equivalent or the possible differences can be shown. In this way the subjective perception of each individual observer is excluded and objectified. In the case of a qualitative deviation, the presentation methodology of the results allows quick reaction and intervention.

Control Electro Dip Paint / E-Coat (KTL)

With today's existing methods, quality control of matt e-coats in the production line was only possible through time and cost intensive analyses.

Due to the applied optical concept and methods Rhopoint TAMS™ is able to measure all kinds of surfaces from high gloss to matt. With Rhopoint TAMS™ the user can now also measure the quality of e-coats in the production line. This is all the more important as the e-coat quality has a direct influence on the perceived and measured quality of the clear coat and thus on the final painted appearance.

The overall picture

The painted appearance of the car body surface depends to a large extent on the underlying waviness and roughness of the steel, aluminum or plastic molded parts before painting.

Rhopoint TAMS™ can be used to measure and map surfaces at any intermediate stage of an automobile production.

E-coat, filler, basecoat and topcoat before and after any polishing operations can be characterized to obtain a detailed picture of the entire coating process. This unique data set offers the car manufacturer new possibilities to assess the suitability of raw materials or to optimize individual process elements - this saves costs and improves quality.

Rhopoint TAMS™ is available as a portable handheld device or as an implemented automated system. RoboTAMS has been optimized for rapid automatic evaluation of vehicle paint quality and has already been tested for concept suitability.

In addition, error detection and error characterization are further options that can be displayed with the developed measurement technology.

Rhopoint TAMS™ is distributed worldwide by Konica Minolta Sensing.
