I somehow doubt spray starch is really what will work, but try......
A test pattern, which everybody can use, would be great,
we could then compare results better.
However it should not be too big, or maybe we need different sizes.
I think a discussion what is the best pattern is on topic.
it should be able to show minimum line width and spacing, and
also it should show how "black" areas come out.
for me a size of 5cmx5cm would be in the interesting range.
i suggest distributing it as PDF and as high resolution image.
discussion very welcome.
