What brand of inkjet transparency do you use ?
I've tried some but didn't got good results.

Well I am new to this group but I'll share what I've found with TT.
I have gotten very mixed results with TT until I turned into a clean
freak. I scrub my clad with scotch bright pads and a paste of commet
(Ajax) cleanser. Then I rinse it for a few minutes under hot water.
Then I soak the board in pure acetone, not fingernail polish remover,
with a paper towel to hold onto the liquid for a few minutes. After
that I wipe the board down with cotton pads until they remain clean
after wiping.
Second, I use INKJET transparency. It has two sides, one is rough
with an emulsion for holding the ink, and the other is smooth and
clean. This smooth side will hold the toner very well, but it
releases it nearly 100% once heated and pressed. There is no soaking,
no scrubbing, no waiting. Just cool the board down and peel it off.
Along with that I also pour some acetone into a container and set the
print out over it letting the acetone vapor soften the toner, prepare
it for transfer, and close any pinholes.
Finally, I wipe the board down with acetone just before I lay the
toner sheet down. I use a hot roll laminator to do my heat transfers.
Sorry, I haven't used an Iron so I don't know about its usage.
You can find the pure acetone at Home Depot in the paint department.
This stuff acts totally different from fingernail polish, plus it is
clean and doesn't leave any residue. Get some, you'll be surprised.
Oh, make sure you wear nitrile gloves when you use it... its nasty stuff.
