Hi Steve, and Roy,

I meant to write some feedback on the QTR/R800/R1800 solution but got
sidetracked by something else at the moment. Here are some
observations based on the available profiles for EEM and my R1800.

1. Printing at 1440 super mode is prone to banding. This is typically
the case with the R1800. It appears there is not enough interweaving
for the 1.5 pl droplets in the Epson driver or hardware. Toned prints,
sepia and cool, are less vulnerable to banding.

2. The supplied profiles were probably made using 1440 dpi mode so
when printing in 2880 dpi results in heavy ink laydown. Without the
ability to create profiles for the R1800 I tried to tweak the image
itself and got a very nice prints using black-only, sepia, and cool
profiles.

3. Printing at 2880 yields much higher dmax.

4. Printing in 2880 dpi mode is very slow. QTR pegs the CPU at 100%
the whole time. But ideally for this printer the printing dpi should
be something similar to the Epson driver's Photo RPM mode which is
probably 5760 dpi. Hopefully QTR will support this mode some day with
reasonably fast printing.

5. The black-only prints at any dpi on the R1800 is very smooth. The
dots are almost invisible. Toned prints look even smoother and very
pleasing.

Sofar my wishlist for the R1800 is 1) having an R1800 as a printing
model (I'm using R800 for the time being), faster printing speed on
2880 (maybe not printing speed but more optimized algorithm in QTR?),
availability of 5760 dpi mode, and of course profiling capability.

Overall with the help of QTR the R1800 can really be an all-in-one
printer for both color and b/w works and of course glossy and matte.
