QTR-Quadtone RIP

John and Josh,

Shaking the carts has made a huge difference and then
printing out some very large prints to clear the lines
of the weak ink.

Things are not perfect yet, I think beause the lines
are not totally cleaned of the weak ink, but I
definately am on the right track now.  It is not
software or hardware or user error but GRAVITY that
has been screwing with me.

thanks everyone for you help and thoughts.  I could
not have done this myself.

Jim
