Files that follow these specs go straight to production — no prepress delay, no surprise charges. Not sure? Send what you have and we’ll flag anything that needs attention before work begins.
Cut & fabrication files (router, laser, knife)
- Preferred formats: DXF or SVG for flat parts; STEP for 3D parts and assemblies.
- Scale 1:1 with units declared in the file (inches or millimeters — just make it explicit).
- Cut paths as closed vector polylines. Put through-cuts, engraving, fold lines, and drill locations on separately named layers.
- Remove construction geometry, duplicate/overlapping lines, and title-block clutter from the cut file.
- Flag critical dimensions and tolerances on a drawing — standard shop tolerances apply otherwise.
Print files (large-format flatbed & roll)
- Preferred formats: PDF (print-ready) or AI with fonts outlined and links embedded.
- Bleed: 0.125″ minimum on all trimmed edges; keep critical content 0.25″ inside the trim.
- Color: CMYK working space; call out brand-critical colors as Pantone spot references and we’ll match on-press.
- Resolution: 100–150 ppi at final size is ideal for large format (higher adds file weight, not visible quality at viewing distance).
- White-ink and varnish layers: separate spot layer named
WHITE/VARNISH, set to overprint.
3D print files (FDM & SLS)
- Preferred formats: STEP for engineering parts; STL (watertight, correct units) also accepted.
- Minimum wall thickness 0.04″ (1 mm) for SLS nylon; 0.06″ (1.5 mm) for FDM.
- Tell us the load case if the part is functional — orientation and infill are chosen to match.
