qmtcolor
Measuring perceived color
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.
- 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

qmtcolor technologies
The qmtcolor is a device for characterizing the perceived color of manufactured products.
It is composed of a chamber with the optical system which allows reliable acquisition of information without influence from the outside world.
The qmtcolor is a polyavelent device which is suitable for use in production or in the laboratory.
The qmtcolor software is dedicated to this application. Interactive visualization of batch measurements in the lab sphere allows advanced evaluation for the operator
The measurement is carried out on a configurable surface (any geometry) with the possibility of averaging and filtering
Customization for advanced management such as automatic sending of results to databases
The qmtcolor incorporates a digital optical system that has been specifically defined to ensure sensitive and repeatable color measurement

All solutions are based on unique software functions
For optical control
To increase production yields
and the quality of the parts
For aesthetic control
For acoustic and vibration control
Measurement and control at the edge of lines and in laboratories
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
