truePIXA Spectral Camera
Until now, the issue of accurate colour reproduction has often taken a bit of a back seat within the context of automated quality control. For example, the colour check in printing technology used to be done manually by the user after printout of the test sheet using a variance comparison. The reason, this procedure could not be automated, was that the spectral resolution of cameras was, until very recently, limited to three sensors (red, green, blue).
With the introduction of sensors in which the spectral sensitivity can be significantly more precisely defined and reproduced, more multi-channel, spectrally selective sensors can be manufactured. These ensure capturing of the original with use of spectral resolution in which minimal colour deviations can be significantly better detected.
truePIXA-6C technology offers the opportunity of multi-channel image capturing within the RGB and infrared area (360-950 nm). It allows the reproduction of an enhanced colour space and allows a more precise colour reproduction in comparison to conventional 3-channel RGB technology. The enhanced versions truePIXA-9C and truePIXA-12C allow measurement applications in the area of spectral reconstructions of the originals.
The image processing concept of Chromasens cameras allows it to be implemented in applications that require colour management, independently of multi-spectral solutions. Furthermore, the cameras support an internal colour management (typical in sRGB or other color spaces).
In printing applications for example, by combination of 12 image channels with a homogenous and wide focused line illumination truePIXA is able to measure colour values simultaneously all over the printed document.
