With ultra fine toner you usually get VERY transparent 'black'.

With normal toner you usually get VERY non-uniform 'black' which can be sometimes improved a bit by placing the transparency over fumes of (for the lack of better word) nitro-based dissolver for a few hours (or heating it under a little preasure shortly after printing).

In both cases you can get 'toner holes' and exposure conditions are SEVERELY limited so you have to get extremly precise exposition with impared contrast.

If you opt to have your PWB develop on some imagesetter instead of printer, you get excellent opaque 'black' and very transparent rest of it. And VERY fine details too! With this kind of film you are not limited to precise exposure and you can overexposure your work without much penalty (in fact it is somewhat a common practice when you have this kind of transparencies to speed-up developing). I don't know for Jordan, but here you can send pdf via e-mail to local design studio and later come by to take film. You also need not to mirror it, since the imagesetter usually does the job.

I've tried lot of different settings with laser printer, and had a lot of problems with developing. Once I've tried imagesetter solution (under the same conditions as with laser-generated transparencies), I've became wholehearted advocate of technique.


I'm not familiar with IIRC abbreviation. Can you, please, expand it for me, google returns a lot of garbage?

Best luck,
