One variable per page: page 2 the pen tools, page 3 colours, page 4 width settings, page 5 marker black and white.
Page 4 is the width calibration. Its PDF states each width as a number rather than drawing an outline — 12, 7, 4, 2 — and widths measured from the contour land on 12.01, 7.02, 4.05, 1.99 without consulting the pen or the thickness setting.
