Very good work indeed!
Your pictures make me eager to work on inkjet printing again ;-)
Also, it is great that you made this with another ink, not MISPRO. I
wouldn't want to buy original epson carts (price), but it makes me hopeful
that many more inks may be suitable.
How did you cure it? oven, hotplate, or hot air gun?
The warming of the board is a good idea, i will try it. Did you pre-etch
the board (does not look like it on the picture)?
How did you clean it, and did you need any wetting agent (break fluid,
glycol)?
