Last year, after reviving an old Roland plotter, we took the chance to make some prints with it. The most refined and finished one was poster with the cover illustration of the Libre Graphics magazine issue 1.2.
The full poster took more than four hours to print. We used an A2 size fluorescent green cardboard and white and black markers. Here is a short video of the printing in action:
