QTR-Quadtone RIP

Extra equipment needed - a light box

In transmission mode the software asks you  to calibrate the eye-one in two steps.
first on the calibration tile, then it asks you to place your spectro on your light box
and click the "Cal Trans" button.
This sets the light box light as being "spectrally neutral' 

Because the calculations are made from the spectral data it would make sense to use a light box whose light output does not have spectral gaps in it's output.
Such as the from daylight tri-phoshpor fluorescents or something with a reasonably good color-rendering index (CRI).
I've only tried it with the transparency back light from our GTI viewing booth and it works just fine.
Once we get out day-view light boxed fixed, a horizontal surface light box would make it more convent than the vertical surface of the GTI.

You could measure your existing light box with your eye-one on emissive mode and just have a look at the spectra.

If you email Robin Myers you can get a fully functional 30 day trail copy of the software. Or you could at the time I purchased it (Sep 2012).
