Digital BW, The Print

I am using a Canon S750 and I have discovered the wonderful world 
of black Only printing of photographs;
or so I thought. I was running out of color cartridges too fast and 
found a
newsgroup called  DigitalBlackandWhiteThePrint@yahoogroups.com and 
have
learned a lot. I read many of the messages and logged on to many 
websites
mentioned in them. As a result, I discovered
http://www.cjcom.net/digiprnarts.htm which dealt with using only 
black ink
for printing the images. It is a learning curve, I admit, but I 
buckled down
and worked with it over the course of a few weeks till I became 
familiar
with the technique. I started print images and noticed almost all of 
them
has some color cast to them, but I chalked it up to the ink and paper
combination. Today I got a screen message from my printer that my 
Cyan and
Magenta inks were running low. I wondered how this could be possible 
because
I was using only black ink; or so I thought. Going back over 
everything
carefully, I reexamined a vital printer setting I thought would not 
be
necessary to set initially. One toggle for color management 
was "Auto" and
"Manual" and I had it toggled as "Auto". Changing this to Manual did 
not
seem to make any difference in the color cast of the prints, and now 
I am
running out of color inks. If I take them out, the printer won't 
print
anything on the paper at all, or if I tape over the ink sensor it 
won't
print at all. Has anyone else had this same problem and solved it? 
If so,
please send me email directly jeades1@... or you can post it 
on this
newsgroup so all can benefit from your knowledge. Thanks in advance 
for any
and all help you can give me with this dilemma.

I can only speak for my Epson printer, but maybe this will help...The
Epson slowly uses the color inks even during BO printing, but only
during the cleaning cycles, not on the print.  

If the Cannon is using the colors on the print then you should be able
to see color dots with a loupe.  That would be the first thing to
check.  If there are color dots then either a setting is wrong or that
printer can't do true BO.

Duh, how dumb can I get?

I checked all the printer settings and found one crucial one that I 
failed to have changed. I was giving it paper profiles instead of 
indicating I wanted to use plain paper for all settings so it would 
use only black ink thinking I would be printing only text, which it 
assumes to be only black ink. Now that I have found that error, I am 
out of ink again and waiting for some bottles from MIS so I can 
refill these cartridges. This will be my first attempt at refilling 
this printer's cartridges, so wish me luck. I'll probably need to 
buy some extra cartridges in case I mess these up refilling. Thanks 
again for all the help you have given me. Before running out of ink 
again, I was able to make a few Black Only prints. I still use the 
front end of Gray Gamma 2.2 and then switch it to 15% dot gain 
before printing and then switch it back to Gray Gamma 2.2 for saving 
the file. I like to have the screen image look like the printed 
image. If I left it at 15% dot gain, it would look much lighter than 
the print. Thanks again.

Your friend in photography,

Good show.  Sounds like you're well on the way.

Good luck on the refills!

What is the back end setting?

I don't use any back end settings. I have a shadowboost curve that 
raises the lower values from what it would be with the front end of 
only 15% dot gain. I know I have still got a lot to learn but this 
gives me consistent results with almost eny paper I use; which is 
Epson Photo Paper, Office Depot Matte paper, and Office Depot Glossy 
Photo Paper--and without any changes other that changing the front 
end to 15% and the shadowboost curve and printing BO. I may be going 
around my elbow to get to my thumb, but so far it works pretty good 
for me still to be a new BO printer. 

P.S. I like it and you like it and that's the only ones we need be 
concerned about.
