test out the 2 sheets of blue press n peel i own.
I used to use this stuff, very expensive, and could be difficult to get consistent adhesion when ironing onto the copper board.
Followed this forums earlier PCB threads about using a printed page from a glossy magazine to laser print to - it really works - good image quality and so much more tolerant when ironing onto the copper board.
Contrary to the previous comment about Brother printers not working - well I've used 2 HL2030s over 4 years without any problems - got two as when I needed to replace the toner and drum, it was cheaper to buy a complete new unit in the new year sales, than the replacement cartridges!
