Updated! Gist: Still way more ink that is probably needed, as it still
puddles, but it no longer strays outside the lines.
I've got this cooking in my food dryer at 145F right now. If it is
still looking wet after a few hours, I may stick it in the toaster
oven at a higher temp.
I should put something like a layer of Future on the back so I don't
waste etchant. Plus I can still use the back for the next test.
Next to try:
Whichever ink color/combo works best, use successively lighter prints
to vary the amount of ink. At some point the puddling should become
more acceptible before the ink dots get so far apart that traces get
holes.
Then thinner traces. It may turn out that wide areas and thin traces
require different amounts of ink, if so that should be a simple matter
of varying the shade of the trace. Naturally it would be much better
to find a setting that works for both!
Then the next experiment may be to load nothing but that color into
all 4 heads of another Epson. The reason being that the printer can
print at higher resolutions when using all heads, as compared to using
only one color or loading the selected color into the black head and
using "black ink only" settings.
