I was wondering if anyone had a better way of "printing" PCB outlines
for reproduction.

I use Ultiboard as my design, routing program. It allows saving the
document to Adobe through Distiller. When I open the document (in
Acrobat) and magnify it, however, it looks as if the doc has been
saved as a somewhat rough bit-mapped file. If I just print the
diagram to my laserjet, everything looks great.

For now, I have been fixing up the jaggies in a drawing program.
Time consuming.

Anyone have a better way -- scanning in hi-res produces too big a
file btw.

Maybe you are using incorrect settings for Distiller? IIRC there was
something about resolution (DPI).

Distiller does have a resolution setting, but this may not help you.

Distiller keeps vector objects in the PostScript as vector objects in the
PDF. It has the ability to resample raster objects, so if the underlying
image in the PostScript has more resolution, then you can improve things by
turning off resampling. Turn it off for all image types (under the
Compression Tab in Job Options). I would set Compression to ZIP, so that
you're using lossless compression.

Otherwise, the resolution setting is for PostScript that queries to
determine what raster resolution is being used. I would set it to a number
like 1200 or 2400, and only set it smaller if you're experiencing file
size/display speed issues.

In Acrobat, if you crank up the magnification and you see the pixels getting
bigger, then you're looking at raster objects. If the pixels stay at screen
resolution, then you're looking at vector objects.

Acrobat normally displays at around 75 dpi, so at the maximum zoom setting
of 1600%, you're one screen pixel corresponds to approximately 1200 dpi.

Most newer laser printers are 600 or 1200 dpi.

I'm saving the file to Distiller from Ultiboard, not scanning it. I
like the suggestion of using an HP G/L translator. The main thing I
want to do is save the files so that I can upload them to the web
for others to use.
