I think it's impossible to tell, since intaglio is a broad term that might mean lines that are etched by acid, such as an Aquatint, hard ground, sugar lift, etc. Or it could be lines etched by hand such as a dry point, mezzotint, engraving, etc. Each technique produces etched lines of different thicknesses, and types, or quality. A dry point will produce an etched line w/ raged edges that will hold ink in a very different manner than an etching.
As the plates are wiped clean w/ the palm of the hand for a LONG time before printing, leaving the ink only in the etched lines, it's impossible to know how much ink is in there. The ink is not measured, it's glopped out of the can w/ your hand and pushed into the lines. It doesn't matter how much ink, as w/ all hand made prints the viscosity of the ink, the paper it's printed on, and the style of the printer are all the things which will determine how the final print looks. An inkjet print, regardless of the type, is something made by a machine. Boo!
