Hi.

On my design today the hatching went “over the top” and I did not discover the error before starting the plot.
Plot was started as I were leaving the house.
On return the result was like this;

The design was supposed to look like this;

I like the effect of the “fail”! More experimentation to come!
(Copper PCB-tracks on green background??)
The “denser” blue is the result of several layers of “paint” over the single layer hatching.
The pens used are Pentel Slicci 0.8mm whith metallic “paint”.
These pens needs higher downward pressure than provided by the pen arm stiff hinge alone,
I use a rubber band to ‘pull” the pen arm down.

The design is adopted from one of my “posts” on inkscapeforum.com.
