Homebrew PCBs

Hi everyone,

I wonder if it is possible to use the photo sensitive Emulsion used in the silk screen making process directly on the blank PCB copper surface. I realize that in the silk screen process there is the silk mesh in which the emulsion gets trapped and then hardens to form the "screen". The idea that I would like to test is whether:

1.	Will the emulsion initially stick to the copper surface?
2.	Will a screen be formed on the copper surface as it does in the case of the silk screening process?

Any comments most appreciated.

Thanks and regards
