Super high resolution prints on transparency in L.A.?

I do live in Los Angeles and need to find someone who can produce a high res
print. I have created 'non-traditional' artwork (for some research) in
Illustrator which contains several thousand super fine lines at a thickness
of less than 1/10 of a millimeter. I need to have the file printed in color
and on transparent foil! This has proven to be a problem and even a res80
LVT print didn't come out just right.

Now, I heard that a LightJet 5000 might be able to print this, but I have my
doubts as to whether those things can print on transparent foil. Also,
everytime I call someone about sending them my file they want it as a 300dpi
Photoshop file, which doesn't make any sense if the output is supposed to
approach 4000dpi!! Again, converting to Photoshop is not the problem, but
the low resolution is - at 300dpi everything is simply going to turn into
mud.

I have already blown hundreds of dollars on failed res80 LVT outputs (a.k.a.
'mud') and am getting a bit frustrated. Is there a place in L.A. that can
produce super high resolution color prints? Also, being able to talk
somebody who actually understand the process and the intricacies involved
instead of some clueless 'technician' would really help ;-)

Any help would be greatly appreciated - I can't believe it's 2004 and I am
unable to get a decent output... <sigh>

Foget LightJet, it's got a native resolution of 305 dpi.

Ditto for Durst Epsilon, native res is 254 dpi.

You need an imagesetter.

tells us that 405 ppi is the highest resolution for the model 5000.

Durst Lambda is 400 ppi.

Inkjet has higher resolution, but is dithered rather than continuous tone.

Lambda's can be printed at my lab using 200 or 400 ppi files.
I would guess the operator can set it where ever but uses 200 or 400
from convience?  or because they are optimal settings.

These are hardware determined resolutions. Other resolutions would be driver
converted (with losses) to 200 or 400 ppi, so it is better to do it yourself
and sharpen the end result before feeding it to the printer. Make sure to
specify 400 ppi output, because 200 ppi is faster and the operator might be
tempted...
