I take great price in researching, constructing, publishing, and finally printing my own charts.
Charts are printed on HP Premium Plus Satin paper. This is a high-quality heavy paper at 286g/metre-squared. I print on an HP 130 Designjet printer.
According to Wilhelm Research, an HP 130 using Premium Plus paper creates prints that can resist fading for 45 years, and under glass, 82 years.
