What a tech pack is
A tech pack is the technical file for one style. It lets the factory quote, make a sample and produce the style without guessing.
What to include
Flat sketches of the front and back with details marked, a measurement chart with points of measure and tolerances, fabric and trim specifications, colours, construction and stitching notes, label and packaging instructions, and the size run with grading.
If you do not have one yet
Send reference photos, a similar garment and a short written description. The factory can build a first sample from these, and the tech pack can be completed from the approved sample.
Keep it current
Update the tech pack after every sample round and send the latest version with each comment. One version of the truth avoids production on outdated instructions.
Frequently asked questions
What file format is best?
A PDF or spreadsheet, with images embedded or attached. Send the latest version each time you change it.
Who owns the tech pack?
You own your designs and files. Agree confidentiality terms before sharing if that matters to you.
