Homebrew PCBs

Hello everyone.
 It's been a while since I've posted anything, I haven't been making my own boards because of all the chemicals but I keep reading the posts from the group.
 
I saw a post on solder mask and always wondered how it was done, I saw the video linked by a post and today I ran into another one.
 
On this page http://www.lpkfusa.com/boardfinish/promask-view.htm there is a link
http://www.lpkfusa.com/video/promask.wvx to a solder mask windows media video.
 
I wanted to buy one of their machines once but they are too high for my budget.
