Hi Texx,
Long time since we've seen anything from you.
There is also a special sheet available (from Jaycar here in Australia as
well as from other sources, of course). It is has a special blue coating on
a heat resistant plastic base and you just print onto the blue side and then
iron it on. Once it has cooled, you just peel off the plastic backing and
voila, you are ready to etch. Certainly much more expensive (about $6 per
sheet in packs or 5 but you can fill the sheet with multiple boards) than
paper but gives excellent results.

Hi Texx,
Thanks for your response. we have tried this technique as well using
normal A4 paper but with variable results. Main problem with ordinary
paper is microscopic slithers of wood which leave gaps in the pcb
track. Better paper is clay impregnated photo paper which is reputed
to give reliable results down to 1/1000 inch tracks.
Some websites recommend matte inkjet paper others glossy. Best
recommendation is to test stickiness with an iron before putting
through laser printer.
Ben is trying magazine paper with photos already printed on them.
I am yet to find a supplier of matte paper!!
