To the OP, thanks a million. If we ever cross wakes, the beers are on me.
I have, well work has, a HP DesignJet 450C inkjet plotter that uses rolls of paper 24 inches wide. When I print some charts the text on the legend, compass rose and notes are impossible to read. I don't know if resolution is lost during the conversion from bsb to png to plotter lingo of HPGL. Any ideas?
