Digital BW, The Print

Ok, Now I think I have a better idea of where you are. First of all, I
would hold off making any judgments about the output of QTR until you have
the eboni cartridge aboard. This is tough enough without having too many
variables to control. So to start with I would go with matte setting, EEM
paper and your ink set.

  With the ink set you are using go ahead with the 1160-vm-gray and
1160-vm-toned settings.

  Calibration does not require anything but a means to print. Although it
isn't the clearest of documents do go through the information that came with
QTR. It is aimed at the Mac but is close enough to make some sense of. It
goes in two steps, first to set the amount of ink each ink position
contributes and then linearizing the curve. The first part can be eyeballed
but the second really requires reading a 21 step wedge with a densitometer.

  Please send your Quad1160.ppd to the decorrales address. If it has the
proper settings then we can go from there. A quick check you can do is to
make two prints using QPR - one at 100% vm-gray and one at 10% vm gray. If
the system is working properly you should see the 10% version as very cool
compared to the 100%. If they are the same, the system is probably
defaulting to the cups 1160 ppd.


  The problems with microbanding sounds more like an 1160 head problem than
anything to do with the driver. When it happens with my system it has always
been due to a clog. The lack of linearity is probably due to the mismatched
combination of ink, paper and the curves. When the system is optimized that
should go away.

  My guess is you are much closer than seems to be the case. Let me know how
the matte print looks.
