Well I tried the cold transfer method and had no luck at all. I tried a 3:8 mix and no transfer at all. I tried a 1:1 mix still no transfer. I then tried a 100% acetone and I got some transfer but not 100% maybe a 50% not good enough to make a board. Maybe my toner is not the right type for this method but I can clean the toner off with this acetone. Maybe its to cold, but even when i heat it up is still gets cold fast as it evaporates so fast.
So will stick to what works for me, I'm very happy with the boards I now make with the heat process I'm using so no need to change plus the acetone stinks and gives me a headache.
