QTR-Quadtone RIP

I just completed a custom profiling experiment for the Piezography K7
and K6 inks.

I have been able to make K7 and K6 profiles of perfect linearization
using a remote method in which the printing of the target and the
measuring of the target both take place at the users location, while
the profiler app runs at my location. The data dumps were emailed to
me as text files by the users, although one person extracted and sent
only the L values (which during the initial experiment was very helpful.)

The data was imported into the Piezography K7 profiling system and
converted into QTR Curve, and emailed back to the user (usually within
a half hour.)

This method works really well. I now have process for Eye1, DTP70, and
DTP40. Users read their targets with MeasureTool and Save the data to
text file. I import the text file and produce a linearized output of
seven (or six) 256 point curves that are specific to the printer.

I did not get any volunteers on the ColorVision device. But if someone
can work out the data dump to be useful to L values, there is no
reason why it should not.

I did not have time to evaluate the qualitative differences between
all of these spectral devices. In the case of the x-rites each was
able to do what what expected, which is all that matters in the end.
The AB values were not used.

This method is geared directly to the users printer without regard to
any averaging. It should make for very perfect output on a particular
printer, and would certainly be better than the canned K7 profiles we
provide to QTR or ship with current systems as an installer CD.

I plan to offer this process after I streamline the procedures on my
end a bit. Right now I can K7 profile for Epson 800, 1800, 1900, 2100,
2200, 2400, 2880, 3800, 4000, 7600, 7800, 7880, 9600, 9800, 9880
printers. I can K6 profile for Epson 1270, 1280, 1290, 200, 300, 1400,
7000, 7500, 9000 and 9500 printers.

It is also possible to do remote K6 and K7 glossy profiling of the MPS
inks if the user is willing to spray or create their own GO workflow.
I do not offer any canned MPS profiles for the glossy Piezography inks.
