Better B/W inkjet prints?

Hi

Although I use a colour managed workflow for my B/W landscape prints. I
do not have profiles for various other printers that I might use for
proofing.

I got to wondering how to improve black and white inkjet printing
without colour management? This was made all the more important with
several digital photography courses I've recently started teaching,
where the equipment available (old PCs and HP 'Office' printers) was
never intended or capable of any real precision.

I've been experimenting with scanning greyscale images and using
Photoshop to create 'profile' curves. The results were much better than
I had hoped, so I've written up my 'experiments' at
<http://www.northlight-images.co.uk/digitalblack.html>

It may not be the 'right' way to get a profile, but it's cheap and made
a considerable difference with the HP printers I tried it with.

Let me know if anyone successfully tries it out ) or has any
suggestions...

bye for now

Look up Paul Roarke and Piezography (different
approaches to the same problem.)

There's a Piezography news group on Yahoo.

Check out limit-gamut inksets and quadtone/hextone inksets.

yup, as it says at the beginning of the web page -- I already use them
for more exacting work...

.... the web page was intended as an -experimental- way of doing it on
the cheap with what you've already got -- it also links to plenty of the
other ways.

Also, various specialist solutions are not going to be feasible at some
of the school computer rooms, where some of my courses take place


For people looking more seriously at B/W there are lots of references on
the site <http://www.northlight-images.co.uk/links.html>

I'd also suggest the
<http://groups.yahoo.com/group/DigitalBlackandWhiteThePrint> group for
lots of good info


bye for now

hey there Keith, with Hp printers you really do not have to go through all the
trouble of creating a color profile for B&W. I have found that going inot the
HP driver utility you can select grey scale printing. It simply knocks out the
use of the color cartridge completely. No more green, blue and or brown over
tones!

Hope that helps!

If you try that on a consumer or desktop Epson printer, you will get
a very "grainy" print because only the black ink nozzles are firing.
By what magic do HP printers get around that issue?

Indeed, the desire to get "all" of the nozzles into action is the
basis of quadtone/hextone inksets and Piezography.

It's no trouble! The article is intended as much as an introduction to
how profiling works (hence all the links and references) and ways round
the severe limitations (IMHO) of some of the equipment I was using at
the time )

I'm afaid HP's black only solution to printing is as grainy as with
Epsons. I used the black only solution for balancing colour. BO printing
can produce quite nice results with large prints (A2 for example) where
the viwing distance reduces the visibility of dots in the hi-lights

My original aim was just to get even tones for proofing, I wouldn't use
any of the HP printers I've come across for serious photo work - given I
use a calibrated, colour managed workflow with custom ICC profiles.

For B/W my own preference is for small gamut inks, but if I had to use a
colour inkset, I'd rely on a good RIP for linearisation and custom paper
profiles.

There is a new HP printer dedicated to B & W printing.

Where can I get more info?

I mean, it's about time. I always figured there was a
niche market there.

Here's the link: http://www.photo-i.co.uk/index.html
It's an 18 page hands-on review. And from what I've seen from this guy's
review and having taken my CF card with a couple of photos on it and
printing them at my local Office Max, I WANT ONE !!
Office Max is selling them for $299.00 + tax. It prints both color and B&W
just great. It will be interesting to see how the other printer
manufacturers counter this one.

Hmm. That link takes me to the top page of some
UK web site. How about just giving me the HP model
number? Kinda hard to guess, from that link.
