qmtcolor

Measuring perceived color
Measuring the perceived color of a surface
Objectively control the color of components

To meet the needs of luxury markets, qmt developed qmtcolor technology to measure perceived surface color so that color control can be objectively measured.

One of the key features of qmtcolor technology is its ability to perform comparative color measurements on any type and size of surfaces. The instrument's high-speed optical system allows repeatable measurement of up to 8 zones simultaneously. In addition, it is possible to apply pixel pre-filtering to each area in order to select the pixels that you want to keep for characterization.

The strengths of qmtcolor technology
  • Up to 8 simultaneous control zones
  • Measuring area ranging from 0.01 to 20mm
  • Integration of spatial variations with analysis and filtering of pixels retained for measurement
  • Highlighting geometric variations of light with luminance histogram
  • 3D visualization of the measurement batch in a CIE76 L*a*b*C*h° representation
  • Repeatability and reproducibility ΔE ≈ 0.6

Evaluation of perceived color

qmtcolor technologies

The qmtcolor is a device for characterizing the perceived color of manufactured products.

A closed enclosure for reliable measurement

It is composed of a chamber with the optical system which allows reliable acquisition of information without influence from the outside world.

A device suitable for production and the laboratory

The qmtcolor is a polyavelent device which is suitable for use in production or in the laboratory.

Software dedicated to color measurement

The qmtcolor software is dedicated to this application. Interactive visualization of batch measurements in the lab sphere allows advanced evaluation for the operator

Surface measurement

The measurement is carried out on a configurable surface (any geometry) with the possibility of averaging and filtering

Connectivity and data enhancement

Customization for advanced management such as automatic sending of results to databases

Latest generation optics

The qmtcolor incorporates a digital optical system that has been specifically defined to ensure sensitive and repeatable color measurement

Technology
Variability in materials, manufacturing processes, viewing and lighting conditions can all influence the final perception of color, making faithful color reproduction complex and demanding to the human eye.
Sectors such as cosmetics, watchmaking, luxury goods or medicine have growing needs for color control to ensure that manufactured products match specifications and thus maintain quality and customer satisfaction.

Collaboration with Mr. Philippe Spay of newColor
Expertise in color assessment particularly in the luxury industry
For almost 30 years now, newColor has been supporting various manufacturers (automobile, cosmetics, luxury, painting) in their management of color and colored appearance and more specifically in the deployment of color measurement systems as well as the integration of colorimetry. A true specialist in Color, newColor's transversal approach allows us to approach color as much through the object and its characteristics, as through humans and their perception.

Five product lines

Acquisition and processing of signals with software, hardware, acquisition hardware and sensors

Autonomous, they are dedicated to measurement for control by sampling in production and for the laboratory

Completely automatic from the feeding of the parts to the control: any non-compliant part is thus ejected and therefore the quality control is 100% guaranteed
