Homebrew PCBs

Finally, I almost completed my Epson CX4200
modification and I uploaded the results of printing
before and after etching. I premix magenta(10ml),
yellow(15 ml), cyan(5ml) and used as a cyan cartridge,
as a printing color I selected black. 
Modification of printer also required a paper emulator
circuit to fake the printer. I also did some tests for
 alignment by making multiple prints on same material
it seems it is perfectly aligned. As a next step I
will try double side PCB printing.  
Notes:
-Photos are under folder Photos/volkan's
-If high resolution images are required I can e-mail
them.
I need to sleep now....
