Homebrew PCBs

I have also tried to use ink as a solder resist. It is difficult to believe but it also acts as a solder resist. I have downloaded the result under 
http://groups.yahoo.com/group/Homebrew_PCBs_Archives/files/Volkan%20Epson%20Inkjet%20PCB/
I am satisfied with the results. 
Steps of solder resist printing with Epson inkjet printer
1-Clean the etched PCB with Ajax 
2-Roughly estimate the position of the printed image on tray and put PCB to this location and loosely fix it by Scotch.
3-Cover PCB with transparency and fix the transparency by Scotch.
5-Set ink color level to -15 for CX4200 
6-Print your solder resist image on transparency
6-Now, using small PCB sticks align the pads of the PCB to the image on the transparency
7-Remove transparency
8-Reprint image on PCB
9-Dry the image and repeat item 8 two times with ink color level set to +10 for CX4200
10-Repeat the above process for the other layer.
11-Cure both sides
12-Remove copper oxide by Tarn-X or diluted HCL
Note: For solder resist you need to use negative image. 
Cheers

 Hi All,
 Finally I have completed my printer modifications and successfully printed double layer PCB.
