Many mechanical problem have been resolved, but there are two limitations that are severe problems for us. The promise that coatings would be available, to allow materials to be coated and run on these presses has not come to fruition. And, it I am concerned that it may not be technically feasible in the long run. Also, certain graphic features cause the heads to wear out in a fraction of the time expected. These two issues may severely limit the useability and economics of this technology, compared to other technologies.
