Printing tips
- Print at 100% / Actual size. “Fit to page” shrinks the squares, so 5 mm stops being 5 mm.
- Ordinary 80 g/m² copy paper is fine. For fountain pens or markers, 100–120 g/m² stops bleed-through.
- The lightest lines are pale on purpose so they fade under your writing. If a preview looks blank, print one page and look at the paper.
