I use HP presentation paper with excellet results! It soaks up water easily and comes off with
much less trouble than photo paper. If you use an iron to do the transfer I found that if you heat the
board with the iron then remove the iron then use a wallpaper seaming roller to run that back and forth
to apply the pressure works well as it is hard to apply pressure with 40sq inches of iron sole plate but only
1/4 sq inch from the roller to apply the pressue..then reheat with the iron as necessary.
another technique that works is to get a piece of wood dowel one inch or greater in diameter and six inches long.
Place the board over the dowel and heat the board with the iron moving the board rolly-polly style over the dowel
and holding the board with a oven mitt so you dont get burned.
I use aDry iron.It has no holes in the sole plate. I got my iron at a discount store for ten bucks!
I now use a Laminator and I get perfect results..I use a GBC H535 which can take up to 100mills thickness of board..
I use a HP 2100 laser printer ! They can be found for between 25 and fiftu dollars on craigslist!

I just purchased some 200 HP Laser 4x6" Glossy Photo Paper off of ebay hope that works with my Dell 1700 laser printer. Cant find
anything but 4X6" in the photo paper, hope that is good.
I also accidentally purchased Staples 4X6 Photo Plus Glossy Inkjet Photo Paper 60 Ct. I already have an inkjet printer, but, I
didn't realize the Staples paper was inkjet until I committed to the purchase. I searched for 'GLOSSY PHOTO PAPER' and should have
searched for 'LASER GLOSSY PHOTO PAPER' oh well live and learn.
I cant find any etchant except for a 'Printed Circuit Board Etching Kit by Radio Shack cat no. 276-1576' on ebay so will have to go
to another source for etchant I guess.
The rest looks pretty easy and straight forward to do.
