QTR-Quadtone RIP

When you look at the detail it sure looks like the LK is not aligned with
the K. Each letter has a LK shadow displaced slightly above the K forming
the detail (letter or line). The printout from the maintenance panel (and
any other non-QTR) source might be sharp simply because it may only use the
K ink. The 2200 QTR curve has grey overlap and therefore uses LK and K to
make 100% black used for the lettering and lines.

Another possibility (I think less likely in this case) is that blurring can
be caused by putting too much ink on the paper (i.e. the Curve is not well
formed). From my experience on a 2200 this would result in spatter and more
general blurring than is the case here.
