ST,

Derek has posted piccies in the past of
6/6 with a photo process and an inkjet
printer here (very household printer)

(took me a while to find it in the archive)

I think this picture Derek took kinda really
shows the difference I think there is between
photo and toner boards.

http://www.pbase.com/eldata/image/62352763

They are 6 thou tracks - and they are uniform
and square across a very wide area (printer
resolution induced random line widths aside).

I could get a TT board with a perfect 6/6
that was maybe 75mm by 75mm when I used to do
TT. (and fit 8 x 75x75 boards on one 150x300
blank to make sure a few where perfect)

I can get a board that is 300mm x 150mm with
6/6 and not have any fear the thing will have
a break or a pin hole anywhere in that
45000 sq millimeters.

(now scratched due to my miss handling are
another issue all together)

Not saying TT has no place in this world.
If you want cheap startup cost it is great.
I don't beleive it gets the same results as
photo though.
