Digital BW, The Print

I've been thinking of trying IJC/OPM  from Bowhaus as a less costly  
alternative to StudioPrint. I only need it for B&W printing. I'm currently  using QTR 
and having just bought an Eye One Spectro, my thinking is that control  of 
individual nozzle ink lay down would be more easily done with IJC/OPM and  enable 
pretty much the same control for B&W as StudioPrint.
 
Any thoughts?  Experience?
 
TIA,
 
Richard Massie

Hello Richard. Not trying to be combative but I'm curious as to what
you find QTR to lack in that area for B&W.

Duane

Hi Duane:
 
That's just it.... I'm curious. I am making really nice prints, but I want  
to push the envelope.
From what I've read about IJC, it offers much the same control of  individual 
ink nozzles like StudioPrint at greatly less cost. I've just moved up  to an 
Eye One Spectro and have not yet begun creating my own curves in QTR, and  I'm 
willing to go the modest expense of trying IJC/OPM as well, deciding which  
is best practice for me after seeing for myself what is possible.
My question is to those who might be using IJC and who might recommend it  by 
describing what it is doing for them. 
 
Richard

Richard, Bill and Scott from K2Press know more about using IJC/OPM for monochromatic 
work than anyone I've met, and with a variety of ink sets.
They would be the folks to ask.

Tyler, thanks for the endorsement.

Richard, we've been using IJC/OPM for a couple years now are are very, very happy the 
results.  

At the time we selected IJC/OPM the only other serious option, IMO, was StudioPrint.  We 
are a ColorBurst shop for our color work so adding the expense of another full featured 
RIP was not desirable.  Compared to QTR, IJC/OPM offered more select control over each 
channel via a more intuitive (but not perfect) user interface.  For what it does, the UI is 
actually better than StudioPrint, again IMO.  All that said, the real quicker for me is the 
transfer curves are applied in 16 bit.  

At the time I did the selection, QTR was applying transfer curves in 8 bit.  I haven't looked 
at QTR in a couple of years so that difference may no longer exist.  We do have a license 
for QTR and use the utilities for creating soft-proof profiles of our IJC/OPM curves.

** Also let me say, just in case any person (troll or otherwise) wishes to engage in 
argument about the merits of 16 bit vs. 8 bit curves, I will not participate. **

We will probably purchase a Canon printer in the near future and I look forward to using 
the newest beta of  "True Black and White".  It's the latest iteration of BowHaus work.  If 
you haven't seen it, check it out... http://www.trueblackandwhite.com/

With IJC/OPM we push K7 inks through a 7600.  Have also used it for a 2200.  Neutral, 
Sepia, split... it don't matta'.  What ever you want, with the splits and blends where ever 
you want.  IJC/OPM can do it.

I've used both QTR and IJC, like both, and might be able to give a bit of
detail here.

That originally was why I preferred IJC also.  The IJC graphical interface
for the curves allowed an easy transition from making the Photoshop curves.

While QTR (at least for Windows) does not have the same graphical interface,
I now prefer what it does have.  I now work in coordinate numbers (pairs)
that are simply taken from a Photoshop curve shape that I like.  The QTR
curve creation system has a way to simply list 50 points in full 16 bit
depth.  It uses the 0 - 100 scale, but it allows decimals.  This huge number
of points and the depth of each one makes QTR unique among the systems I've
used in terms of the accuracy one can control each of the jets.

So, I simply use a PS curve to give me the approximate initial points.  From
there on, it's the points list.  I use them like sliders, checking the curve
shape with a preview as I go.

>... the transfer curves are applied in 16 bit. 

I think they both are 16 bit now when it comes to applying the curves.  The
QTR limit is that while the curves are high bit depth, the input and (or?)
output files are 8 bit.

Paul,

I've been setting up my R800 for 3MK printing. Been doing a lot of 
nozzle checks because the printer's been sitting un-used for a while.

Since I'm not going to print "color", do you think it would be alright 
to use distilled water in the other carts?

Or maybe windshield wash fluid...?


Thanks,
Scott

Paul,

The windshield wash fluid is listed, in order, as:

Water, Methyl Alcohol.

I use MIS cleaning fluid.  You can also buy MIS "UC base" and dilute it
50/50 with distilled water.  The water by itself will have lower viscosity
and will not have the other things in it that might help keep the printer
clean.  On the other hand, it probably will not directly hurt the printer.

I would not try this without knowing what is in it.

Some of the inks have used alcohol, but small amounts.  Given all the
variables (including viscosity), however, I'm just not knowledgeable enough
to say whether it would be safe or not.

Paul,

I just visited CompUSA and while there, I compared the yellow carts of 
the R1400 and the R260.

The carts LOOKED identicle.

HOWEVER, I noticed (accidently) that the R1400 cart will fit into the 
R260, but the R260 cart would NOT fit into the R1400.

I took a second, side by side look at the carts, and couldn't see a 
difference.

Just a heads up in case you haven't looked at the R1400 yet.

Scott
