What file format should a fashion tech pack be in?

Short answer

Send your factory a single, versioned PDF for the final, factory-ready tech pack. Inside your team, keep source files in Adobe Illustrator for technical flats and Excel or Google Sheets for the BOM and size charts. The F* Word automates the draft, validation, and export to a factory-ready PDF while keeping structured data linked for fast edits.

A PDF freezes layout and numbers so the factory sees exactly what you approved. Illustrator keeps linework crisp at any zoom, and spreadsheets hold sizes, tolerances, and materials in clean tables. Use these as sources, then export a locked PDF for the official handoff. The F* Word adds AI checks on specs and tolerances before you send.

Factory-ready export requirements

A factory-ready tech pack needs a static, universal file that preserves line art and tables. PDF is standard for that handoff because it renders the same on every machine and blocks casual edits. Teams that attach live AI or XLSX files see accidental changes and version drift, which turns into wrong POMs on samples and chargebacks later.

Keep the live record inside your system, then export the PDF as the contract view. As Kumar, Sidhik, and Lokam note, "the tech pack is a living record: versioned, approved, linked to its BOM and size chart. The PDF export freezes it and severs every link" (The Machine-Readable Brand, p.33). The F* Word preserves the living data, runs validation, and then produces the frozen PDF you can send with confidence.

Do not hand factories screenshots or chat images. Each handoff away from the design system loses context: a PDF export freezes the record, and email attachments and cropped screenshots lose even more. Use a single PDF with clear versioning, not fragments.

Source files for design and spec

Use Adobe Illustrator for vectors. Technical flats in AI scale cleanly, so a stitch path or bartack callout stays sharp when a pattern maker zooms in. Keep layer names and stroke styles consistent so the legend on your PDF reads the same way on every page. Export line art to the PDF rather than pasting raster thumbnails.

Use Excel or Google Sheets for structure. The BOM, size chart, grade rules, and tolerances live best in rows and columns. Spreadsheets let you sort trims, colorways, and supplier SKUs without touching the art. Keep POM IDs in the sheet aligned to callout IDs in Illustrator. The F* Word ingests both kinds of inputs and ties them together, then checks for missing tolerances and spec clashes before you export.

Tool and file comparison at handoff

What each tool or file gives you at the factory handoff, and what you still need to add

Checklist to package your handoff

  • Lock the layout. Use vector flats, labeled callouts, and a table of contents. Embed fonts in the PDF.
  • Make the numbers complete. Include BOM with supplier codes, size chart with grade rules, and tolerances on each POM.
  • Cover the variants. Add colorways, trims placements, and any print or wash notes with scale and position.
  • Stamp the source. Put style code, version, date, and approver on the cover and footer.
  • Package one file per style. If you must split, number pages and add a manifest page.
  • Share with intent. Send the PDF as a single attachment or link, not screenshots. Each handoff away from the design system loses context: a PDF export freezes the record, and email attachments and cropped screenshots lose even more.

If you start from a photo or concept, use AI with a check step. See what to validate in image inputs in this guide. To translate creative intent into specs that factories can act on, walk through moodboard to tech pack.

Where The F* Word fits

The F* Word is built to create a correct tech pack, not to be your PLM or a 3D tool. It generates a factory‑ready draft in 8 to 10 minutes with BOM, POMs, grading, and construction notes from a sketch, photo, or design input, as reported in State of AI Fashion 2026. Teams spend time where it matters, then export a clean PDF for suppliers.

Validation is the edge. The F* Word runs checks on specs, tolerances, and BOM before samples are cut, which reduces the back and forth that burns weeks. The same report notes that fashion teams juggle an average of nine separate apps per collection. By handling draft, checks, and export in one pass, The F* Word cuts tool hopping for this step of pre production.

If your process starts upstream, The F* Word can build moodboards and carry decisions straight into the pack so intent and numbers stay aligned. See the flow in AI tech packs and the hands on walkthrough in the automated tech pack generator. For planning season workload and savings, review benefits of automated tech packs and how many revisions a typical tech pack goes through.

As Kumar et al. put it, "Artifact liquidity is the degree to which such an object can move between people, systems, and partners without getting scrambled" (The Machine-Readable Brand, p.57). The F* Word keeps artifacts liquid inside the system, then gives you the frozen PDF for the factory so you can move fast without losing the plot.

Frequently asked questions

Why PDF and not send AI or XLSX files to the factory?

PDF renders the same everywhere and blocks casual edits, which protects approved specs. Live AI or XLSX files invite untracked changes. You can keep the source files for your team, but for suppliers send one versioned PDF so measurement and BOM tables cannot drift from the flats.

Does a 3D export replace the tech pack PDF?

No. 3D garment simulators like CLO 3D or Browzwear help you see drape and proportion. Factories still need a pack with POMs, tolerances, BOM, and construction notes in a static PDF. Use 3D images as context pages inside the PDF or as a separate visual brief.

How fast can I get a factory‑ready PDF and what is checked?

The F* Word generates a first draft in 8 to 10 minutes with BOM, POMs, grading, and construction notes, as measured in State of AI Fashion 2026. It runs validation on specs, tolerances, and BOM before samples are cut, then you export a single PDF. Teams that used to spend 4 to 16 hours per pack by hand can move faster and with fewer misses, according to the same report.

Why should I pick The F* Word for tech packs instead of a PLM?

The F* Word creates and validates the tech pack and exports the factory‑ready PDF, while a PLM is your system of record. It is not a PLM and not a 3D tool. Use your PLM to store and route approvals, and use The F* Word to draft, check, and package the pack in one flow.
