Inkscape to A0 and 36 × 48 in copyshop sheets

What copyshop sheets need

• ✓Sheets at the real paper size: A0 (841 × 1189 mm) and Arch E (36 × 48 in)
• ✓As few sheets as possible, turned whichever way fits better
• ✓Every size on its own layer, so the shop can print just one
• ✓A test square on every sheet

By hand, it's pages at A0 and at 36 × 48 in with pieces arranged for each; again, the PDF export flattens size layers into one.

The Sewpress way, from Inkscape

1. 1
   Set up your layers

   Use Layers and Objects to make one top-level layer per size (S, M, L) and shared layers starting with an underscore (_grainlines, _notches, _test). Sublayers are fine.

2. 2
   Export for Sewpress

   Save as Inkscape SVG. Inkscape layers are exactly what Sewpress reads. Inkscape's own PDF export doesn't keep layers as PDF layers, so upload the SVG.

3. 3
   Upload and check

   Since 0.92, Inkscape uses 96 units per inch, the same as Sewpress. Files made in older versions used 90, which reads as 93.75%; Sewpress spots that on the inspection screen.

4. 4
   Build copyshop sheets

   Sewpress places your master once and builds A0 and 36 × 48 in copyshop sheets, measuring the test square in each.
