I used thin glossy magazine paper. Worked very well several times!
Cut out a mainly white (could be printed on)part of the page of the magazine
Stick it to the A4 page on top edge using normal sellotape
Print on the glossy paper, then remove the glossy paper from the A4 sheet
Clean your PCB with fine steel wool and alcohol (has to be absolutely spotless!)
Laminate with PCB (now this is the tricky part, make sure your laminator is hot enough, but not too hot
) and run it through it several times (at various places of the laminator to harvest the heat from the entire roller).
let it cool down
Stick the PCB with paper into a bowl with lukewarm water and let soak for 10-30 minutes.
If you've done everything correctly, you will now be able to remove (slowly) the paper. there will be leftover bits of paper and fibre stuck to the board.
Now brush the PCB with an old tooth brush to remove all the remaining paper and fibre. If your toner stuck correctly, this will not strip it down, just be gentle
Dry the board, fix any broken traces (I only had to do this once)
Etch
This board was made using this method and came out pretty well. Only had to touch up the top right trace as I was impatient when pealing the paper and pealed the trace too. I have also done some boards with BGA package with this method. If you do it right and have the right printer, you'll be fine!
