Digital BW, The Print

Reading through Clayton's excellent pages re. BO and general B/W 
printing, my old "art" printing memories came back! :) But since we 
are in the 21st Century, and using this i950 printer, I was wondering 
and need some clarifications on this BO process:
- as I understand BO stands for using ONLY the black ink cartridge 
for printing grayscale images
- if this is true, than what happens with the rest of the inks, you 
simply take the out? I guess that could imply some problems with the 
printer itself.
- or, you can replace the remaining 5 slots with empty carts 
and "force" print in BO only?
- as far as I know, even in grayscale printing normally used for 
text, the "black" ink on paper is not 100% black, but a combination 
of black and other, thus resulting in a color tinted B/W photo print 
straight out of the application.
- since I guess is possible to replace the whole printing head in 
this printer, would it be advisable to have a separate head only for 
the B/W printing? If such, where or how can you find an extra head 
since I don't think Canon is selling these separately?

Any input would be greatly appreciated. I looked into the archives 
for the past year and more, couldn't find any specific info on this 
printer model. I understand people here are more Epson geared, but 
even some general info re. my issues above would be helpful.

Thanks,
Ara Ghemigian

Hello Ara,

I don't know about Canon printers, but with Epson models you must
leave them there.  The printer won't run without them. The printer
periodically does its own cleaning cycles, and a little bit of all the
inks gets injected through the head.  So even though you do only BO
prints, eventually all the inks get used and have to be replaced.

Regards,
Clayton

Hello Ara,

I don't have a Canon i950 but I think all printers have similar 
characteristics; one of them being the choice of using only black 
ink for making a print. I do have a Canon S750 that my son is using 
and it can be put into Black Only mode from within the printer 
driver. On one screen is the choice of Black/Color. On my old 
printer, I needed to tell it that it was printing "text". Maybe some 
of this will lead down an avenue of discovery withing the Printer 
Driver settings.

Your friend in Photography,

Thanks for your reply Johnny. However this i950 doesn't have a
straight "black" only position for printing. All black on white text,
images, are printed using the color inks as well, that's why is
impossible to obtain a b/w print straight out of the printer's
driver.
I guess the original design idea was to build a color photo printer,
with less regard for b/w printing!

I did some tests last night, per Canon's tech support, in order to
eliminate the bluish tint that comes in grayscale mode printing. Even
with extreme settings in the color adjustments + grayscale mode,
nothing happens! Basically, the color manual settings have NO
influence in the grayscale printing! I don't know if this is a design
fault, but it doesn't work. Which means that there's a preinstalled
profile for text, b/w, grayscale printing, that can't be altered by
user.

So, after a bit more reading, I went to Lyson and installed some ICM
for this model. I printed some tests but I can't give a final comment
yet, since it was too late to view the prints in daylight. Sure, the
ICM is meant for some of their ink+paper combination, but I'd like to
see at this point if there is possible to produce a closer b/w print
just by using another profile. Sure, it should be possible to create
a profile in PS for ex., just that I wanted a quick image of what is
possible.

I'm not sure if I asked already this in this forum, meanwhile I've
found a Canon printing group, but would it be possible to replace all
5 color inks with black carts and use only BO printing this way??

PS - ha, I see I asked this in my original message already! :)

Hello again Ara,

The text mode is the choice to make to use only the black ink 
cartridge. You may be able to choose the dotss per inch setting also 
to get a higher resolution print. Coordinate this with the 
information on Clayton Jones; website and you should be up and 
running in no time (?)

Your friend in photography,

Johnny, i950 doesn't have "text mode", only grayscale and color.
Thanks 
Ara
