Digital BW, The Print

Hi

I'm quite aware that this is the group where all the serious and 'proper'
ways of doing curves and profiling are discussed, but I thought I'd post
this for people who were just dipping their toes into B/W and wanted to do a
bit of simple experimenting...

--------
Although I use a colour managed workflow for most of my work (icc printer
profiles and special inks for B/W) I've been experimenting with generating
Photoshop curve 'printer profiles' for a completely unmanaged networked
printer (HP K80) that sits in my office. I use it for the odd quick B/W
draft where I want to get an idea of the tonal balance of a picture -- it
also saves walking round to where the main printers live :-)

I'd tinkered with this a while ago and revisited it after seeing some of the
dire set-ups in school computer rooms.

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. Nothing shows students the benefits of monitor calibration better
than getting everyone to open up the same image, calling them to the far end
of the room and asking "OK, which one is the right colour?".

The profiling 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 has also proved quite useful as a teaching aid, when I was talking about
colour management and profiling. I have an original print of the
downloadable test image (from the web page) ready for people to scan and try
for their own 'profile'
-------

I've got some more 'advanced' B/W stuff on the site as well and would also
recommend anybody new to B/W to check out the group archives

I'd welcome any comments...

bye for now

I am getting a slowdown in printing when sending a large file to my
Epson 10K. It starts out fast (in high speed mode) and then starts to
slow down to a crawl. It prints but much slower then it ever did in
OS9. I have tried connections via USB and network and get the same
results. I am pretty sure that it is a data transfer rate problem but
have been told that there is no way to manage what disk it spools to,
like it could in OS9. If I print a small file it prints very fast.

Mac G5, OS 10.2.7

Thanks for any ideas,

I had that same problem, but for some reason it's now printing fine.
When I had the problem I noticed printing would speed up if I had the Print Center 
open and on top (not behind any opened app) I just couldn't multitask :-(

I have tried that, did not help. Thanks for the idea.
