Homebrew PCBs

I use a small heat-gun to preheat the board to about 75C. This heating is done on the feed tray
and carrier so it is ready to go when I hit the print button. I actually continue to heat while it
is printing if it is a long board. You have to be careful to not melt the plastic on the back of
the printer, ask me how I know. The cure time is the same as Stefan's about 3 minutes until the
board is somewhat oxidized, slightly purple. I think most people are using matte paper setting
with best photo. Is there is another setting which gives a better dot pattern but is is a lot
slower. The board gets to cold using that setting. I'm not sure what you mean by " where is the
file".
