[Waverley ARS] Restorers and builders first Meeting Tuesday 5th

[Eddie Hanham]

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!!

Some referneces are:
