In principle I agree Joel,
but the problem really lies not really in the print versions,
which are always going to be poor representation of a digital image...
rather in the PDF version, which contain a mashed, lossy compressed,
resampled and generally destroyed version of the image data.
Let us not forget, out microscpes are fanct spectrometers that collect numerical data.
A digital image is not analogue artwork, its just a table of numbers!!!
we would never allow a text table of numbers to have its information destroyed like this
on the way to it being read by a reader/reviewer, so why do we accept it as normal for images?
We meed to change the way publication works, and make sure editors understand that images
are tables of numbers and should be treated as such.
The original non destroyed image data should always be made available over the web.
Chemists and physicists thing cell biology etc are very very soft fluffy disciplines,
and trust very little they read of out work,
exactly for reasons like this.

sure, it sounds like a good plan, but in the end the image is always destroyed at the final stage - the printer,
which imposes its very limited capabilities on any image.
We can try to make sureimages look nice, but this really is only art.
What a reader really needs is access to the full resolution original image to open in ImageJ/Fiji etc.

I agree ver strongly. We must to accept badly destroyed images , even in print.
Lobby your editor until you get what is right.

but the images are still not really good enough for someone to take and re do your image analysis,
or make their own new measurements from .
this is a basic requirement of scientific publication,
and is harly ever me in our discipline,
and this is very wrong.
Physicists laugh at us... and biochemists.
there is no technical reason that raw data can not be made available on line
even big screens,
its just missing infrastructure that needs to be put in place.
Where is our biological image equivalent of the PDB database, the GENBANK database,
all the other databases other disciplines have.
Where is ours? We need to get that funded and organised through eg Euro-Bioimaging project.

Or we need to force our publishers to get smart about the kind of images we give them.
and how to treat them.
I would suggest we be proactive here, rather than defeatist.
No matter how hard we try to make a well formatted plate for the publisher,
it will most likely still be mashed by the time the pdf arrived on a readers screen.
We need to educate the publishing system of our needs.
I suggest using the argument that our images are 2D/3xD tables of spectroscopic measurement NUMBERS,
and should be treated as such, not as photos - which they are NOT.
