I have found that pressure is as important as heat.
Apply a lot of pressure while during the ironing process.
Everyone talks about heat, but no body mentions pressure.
Also, preheat the PCB with the iron before you apply the laser copy.
Use a paper towel between the laser copy and the iron and/or copper clad.
Press hard.
I get very, very good results with virtually every glossy paper that
has been mentioned here.
