But of course, the image is still made with CMY dyes - not RGB.
The Lightjet (or LVT, Lambda, Chromira, Frontier, DLab, Fujix, etc.) is just
a machine used to expose photographic media in place of an enlarger. These
devices all expose photo media with colored RGB (additive) light, but the
resulting processed image is still CMY (subtractive) regardless of how it's
exposed. It's CMY and not CMYK because there's no black "plate".
Now a monitor is a true RGB device, as is a video projector. They're fed RGB
data and they produce their images with RGB light.
