QTR R800/R1800 Performance And Evaluation
Of course I’d have never sat down to write this piece if the results were
not convincing. As background, I first learned to appreciate a “good”
black and white print using Dupont Velour Black silver paper under the tutelage
of an old European master by the name Boris Dobro. He taught me that the black
in a print should have depth and be neutral in tone—although I tend to
prefer just a slightly warm over a cool black.
I picked a few dozen images to print, each of which was individually converted
from Gray Gamma 2.2.icc to the QTR - Gray Matte Paper.icc profile in Photoshop.
In most instances I did some minor tweaking of the image on screen. After getting
a few image files ready I made a few prints on some Epson Enhanced Matte Paper,
probably my least favorite fiber-based paper, to see what I’d get. I was
surprised to see really good detail in both highlights and shadows, but some
prints were just too light. Although encouraged, I realized my eye needed to
learn more precisely where to set the mid-tone gray center point in Levels.
After some more practice in converting to this new linear image file (work space)
profile, I got it zeroed in, and my resulting prints were looking better and
better, really quite good even for a paper that produces good color results,
but not really dramatic black and white prints. I was reminded of a comment
Roark made in the course of our conversations that black and white prints need
a really exceptional D-max, a deep black density, because unlike the diversity
of color, black and white depends entirely on the range of shades of just one
tone.
As I progressed I tried printing on a greater variety of papers supported with
Curves/Profiles made for QTR by Roark, from the surprisingly effective Epson
PremierArt Scrapbook Paper to Moab Entrada and Hahnemühle Pearl. And, after
a Curve/Profile was made for it, I also printed on my recent discovery of a
very modestly priced watercolor paper by Premier Imaging, also sold as Illuminata
Watercolor by InkJetArt.com. It produced a good D-max and very respectable black
and white prints. I also confirmed what Roark had suggested—that using
MIS Eboni inks you can obtain a distinct range of image tones from very cool
blacks with some “bright white” types with OBAs (Optical Brightening
Agents), to quite warm tones with some of the “natural” designated
fiber matte papers.
My tests did confirm that some of the “new” luster fiber papers,
and especially papers with a microporous coating, do not print to best advantage
with the MIS Eboni pure carbon inks. I found that different kinds of subjects,
such as landscapes, nature, documentary, and portraits, are favored by using
different brands and types of papers. I would imagine this is as much a matter
of individual taste as it is an objective observation on my part. As I was finishing
a sizeable bundle of prints I checked the ink levels of the three MIS Eboni
cartridges I used; they had only been lowered to a little less than half their
full volume. From this I conclude that you get a lot of ink mileage using undiluted
black inks in three channels.
The bottom line is, this new MIS/QTR black and white printing capability added
to an Epson R800/R1800 setup is very worthwhile, especially considering I could
not detect any difference in my color printing with the very same Epson R800,
and that includes printing labels on CD-R discs.
Mac Installation
The file downloaded from QuadToneRIP for an Apple Mac is a standard installation
file, so proceed by following the on-screen dialog instructions and the QTR
driver components will be installed in the system, leaving a folder on your
desktop containing two essential folders and other items not installed. So create
a folder and name it QTRIP2.5 and place it on your HD in the Applications folder.
Then drag the contents in the folder the installation put on your desktop into
the new QTRIP2.5 folder now in Applications.
|
Under your new QTRIP2.5 folder you will find a Profiles folder,
which you should open. Then in Profiles go down to the QuadR800/R1800-3MK
folder and open it. There will be a list of Curve/Profile
3MK files, and at the bottom there should be an InstallR800-3MK.command
file or an InstallR1800-3MK.command file; double-click on the
one that corresponds with the printer you are using. Activating
the Install.command file will place the QuadR800/R1800-3MK printer
into the list of active printer drivers in the Apple Printer Setup
Utility dialog, which you may want to launch after restarting
your system to confirm the driver is present and available.

would suggest going to the source and reading: www.paulroark.com/BW-Info/R1800.pdf.
In addition to a detailed description of why 100 percent carbon black MIS Eboni
ink works to advantage, Paul Roark discusses the workflow and goes into how
a critical user can control the process and “profile” papers themselves,
as well as detailing his own testing of a variety of papers that can be used
with his new black and white printing method. And, while you are at it, you
might want to see what Roark is all about as a photographer by going to his
homepage at www.paulroark.com
where he provides access to a gallery of his images.
