What is the follow up of the imaging phase ? I can understand
that it is great to have a digital image of that quality archived
for later use and I can even imagine that a nice 7 hues loaded
inkjet could make the right print but in between there must be a
very sophisticated image editor, a very wide colour space and
suitable colourmanagement + colourengine. Isn't that the
bottleneck at this moment ?
