I remember two or so years ago that I got this transparency in a demo
pack. The print quality was very good, although I did not use it for
pcb. If I remember correctly one side was not glossy and this is where
the ink sticks on. I could not find transparency paper like this again,
seems like most today are for Laser printers. So do you have a product
name?

Since this thread started I've learned to set up and use the CAM process
(one of those -I know I must figure this out someday- situations). So I
got as far as PDF's.

As a few of my customers are in the printing trade, I've made use of
their photolitho department for this. Before  the days of photo plotting
I did a 2x size print out and shoot it through a reduction camera to 50%
on positive film (bromide film). Works great.
This and photo plotting takes time and sometimes money.

This particular project I am trying to stay in-house as much as
possible. I am testing to see if it is feasible to make critical spaced
double sided prototypes in my workshop. So far it looks good, all the
costs are still lower than set up costs of a board house.
