Additive color printing brainstorming

[Nicholas Lindan]

If the thing is computer controlled there is no reason you can't have CMY controls and an RGB light source. It's just a mathematical transform; Photoshop does the reverse on the fly when you open a CMY image and display it on an RGB monitor.

If there isn't enough confusion in your life then you can have a switch that switches the controls between CMY and RGB - you can try printing with both in the same session.

RGB light source would be difficult and expensive to engineer. Using RGB filters would be cheap and work with my existing enlargers. The point about not being able to D&B is well taken.
