1. What is a neutral RGB space? Adobe RGB or sRGB?
AdobeRGB, sRGB, or any Photoshop matrix-based workingspace is, by definition, neutral and linear.
2. What does neutral mean? non-neutral and non-linear space?
Neutral means that even amounts or the channels (R equals G equals B) makes a neutral gray. So the gray axis does not worm around as it does in a printer space, and does not veer to a non-neutral, uncontrollable paper white at one end, and a non-neutral, uncontrollable ink black at the other. Linear means that each of the units between 0 and 255 are evenly spaced, not variable as they are in a real-world device space. No skips, bumps, and gaps. An idealized space, fit for repurposing to any output device, not the warts and pimples of one output device built into your image.
3. Should the image be outputed, device specific (only for the
Frontier) and nothing else, can't this be an exception?
In the case of most devices, the image is never converted to the output space by the user, it happens on the fly, on the way to the printer, from settings chosen at print time. With the Frontier, on the other hand, you will probably manually convert to the printer space in Photoshop, and save to an output folder, though I would recommend making a Photoshop action to automate this process.
