Affinity Designer 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 artboards at A0 and 36 × 48 in, pieces arranged for each, and a PDF per sheet size.

The Sewpress way, from Affinity Designer

1. 1
   Set up your layers

   Make one top-level layer per size (S, M, L) and shared layers starting with an underscore (_grainlines, _notches, _test) in the Layers panel.

2. 2
   Export for Sewpress

   Export SVG: each top-level layer becomes a named group, which Sewpress reads as a layer. Upload it, and check the layer list and test square on the inspection screen.

3. 3
   Upload and check

   SVG export settings vary between versions. If the inspection screen says your test square reads 75 mm, the file was written at 72 units per inch: choose 72 there and it's fixed.

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.
