I would not use coloring for the first trys.
I am rather sure it does nothing positive apart from letting you see the
image.
I would drop the board in etchant to see if it works, even with colored
ink you can't tell if the layer is thick enough and has no voids.
Wouldn't it be great to fill the color cartridge with different color
inks to make a really stunning component legend?
I think i really have to get a printer... However i want to wait until pebo
has more results...
It would also be possible to print a soldermask i guess if the right
ink is found...
What i still really fear is that the drops may not be forming a closed
surface.
After all for inkjet transparencys you also need a coating...
i fear the surface tension forms little drops, and there is nothing to
spread and suck up the ink, so it will just be a grid of small drops.
The solution would be some 2 component system, hardening a already present
layer.
However this increases the effort and it may already be more difficult than
TT. also the high resolution may be decreased.
Well, we will see...
pebo, i look forward to the next experiment results....
