Hi Gene
The Canon 9000 looks interesting at 12 pigmented inks and 60 inches wide.
That's enough for most things I can imagine. Making an image nice and
sharp enough for this size might be hard....and getting enough resolution
might even challenge the H2D-39. Working with such an image would
challenge a computer. Or would it? What is the state of the art? The
Bleeding Edge?
Yes, that promises to be a very good printer, if initial user experiences
come back
positive. I'm guessing Canon's gonna spread the 12-pigm'd-inks thing
throughout the size
range, bringing out a 24" and even a 36" at some point. It'll be fun to
watch Epson and
HP scramble to keep up. Epson's vulnerability is the black ink change
cost, and HP
doesn't have pigm'd inks at 24" (yet ... birds are heard singing that it's
coming soon).
My current large printer is an HP DJ-130. I am able to
make nice 24" x 36" prints from D70 (6MP) images.
Images must be sharp, but that's a lens thing, assuming
photographer skill. I am able to make nicer images from D200
(10MP) images. Pixel-peeping the photos leads me to believe
my lenses have more resolution than the camera's able to eat.
I process the master of each image in Photoshop,
then create a Level 12 (pretty dang pixel perfect [PDPP]) JPG for
printing from QImage. I use Level 12 JPGs because they're the
smallest PDPP form of the image, making QImage and DJ-130
digestion as easy as possible. That's a good thing to do when
making large prints. Hardware and software wants to fail with
large amounts of data, so we'd like to optimize not doing that.
Thinking about a 60"-wide printer:
Making a 60" x 90" print means I'd be covering 6.25 times as
much area as a 24" x 36". It'd be nice to have 100MP to spread
around. But I sniff my 10MP, on a SHARP image, wouldn't look
all that bad from most practical viewing distances.
For a computer to handle such images, you're going to want
CPU power/speed and lotsa memory. Pretty close to top of
the line stuff. A coupla thousand could
cover it for a smart shopper / build-it-yourselfer. Most folks
would spend more. But it'd be doable.
The future approaches at accelerating rates. Fasten your seatbelts,
and be sure to take sharp sharp sharp pix with pinpoint exposures
and minimal noise; bigness reveals flaws as easily as it does excellence.
