Homebrew PCBs

good day,

i'm a newbie on photoresist method. i've read homebrew's archives/forum 
about how to stick dry film to pcb, all methods involving laminator. is 
there some way for me to stick dry film without laminator?. i've tried 
without it, just by hand and pressed it with warm iron. the result is 
like this one. my exposure time is about 2 - 3 minutes.

so many wrinkles here and there. and i have no confidence to develop it 
too long, sodium carbonate will dissolve the traces i'm afraid.
if laminator is a must, what kind of laminator should i buy?what kind of 
spec? (roller thickness)

i need many enlightenment here..

thanks in advance

regards
