Tech Pack Essentials for Custom Apparel Manufacturing

Customization & Manufacturing

A tech pack is the document a factory works from: measurements, construction, materials, colourways and artwork placement for one garment. Without one, every sample becomes a conversation, and each production run drifts a little further from the original intent.

Sellers moving from blanks to custom development meet this document at the first sample request. A tech pack that answers the obvious questions reduces sample rounds from four to one, and it protects the fit when production scales.

What Goes Into a Tech Pack

Start with a technical flat drawing of the front, back and any detail the factory must reproduce. A flat shows seams, panel breaks and trims that a photograph cannot, and it is the page everyone refers to during review.

Add the measurement table with a tolerance per point. Chest, body length, sleeve length and hem width are the minimum, and each row needs a target and an acceptable range so a submitted sample can be graded objectively rather than judged on impression.

Include a grading note for each size. A file that lists one size and says grade accordingly leaves the pattern maker guessing, and the guess shows up in the largest sizes first.

Then specify materials with a reference for each one. Fabric composition and weight, thread type, labels, zips and packaging all belong in the tech pack, and a reference swatch attached to the file prevents a substitution that looks close on paper and different in hand.

Construction Details That Prevent Rework

Name the stitch types and seam finishes. A cover-stitched hem, a flatlock seam or a taped neck each changes how the garment behaves, and a factory will choose its default unless the tech pack says otherwise. Defaults are where fit quietly changes.

Specify label placement and content. Care labels, country of origin statements and fibre percentages are legal requirements in most markets, and their position affects comfort as much as compliance. Building them into the tech pack means nobody adds them later.

Document artwork placement with coordinates. Print or embroidery positions measured from a named reference point stop the drift that appears when artwork moves a quarter inch between runs. The measurement conventions in Print placement standards for custom apparel transfer directly into a tech pack.

Build the Tech Pack Before the First Sample

Write the document, then request the sample. Factories quote from the pack, so a complete file produces a comparable quote while a partial one produces a guess. The difference shows in the sample rather than in the price.

Review the sample against each line and mark pass or fail. A written record turns a sample round into an objective review, and it gives the factory specific points to correct instead of a general request to improve.

Keep the approved sample as the reference piece. The tech pack describes intent while the approved sample shows the result, and the two together settle any disagreement about what was agreed. The reviews set out in Tech packs for custom apparel production follow that sequence.

Version Control Keeps a Tech Pack Useful

Date every revision and note what changed. A factory producing from version three while the brand works from version five builds the wrong garment, and the error is expensive on a full run. One file, one current version, one changelog.

Limit who can edit. Marketing changes to colour names should not rewrite a measurement table, and the two belong in different sections. Separating the technical pages from the commercial ones prevents accidental edits that production follows.

Keep a reference photo of the approved sample inside the file. Pictures settle questions about stitch density, trim colour and label position faster than written notes, and they travel better between factories.

Then align the document with the business model. A program built for stock and dropshipping needs a tech pack that can be reordered without revision, while bulk production tolerates more change between runs. The trade-offs are compared in Print on demand vs dropshipping: which model fits?

Tech Pack Details That Reach the Customer

Size range is a specification, not an afterthought. A tech pack that stops at a standard run limits the market, and extending it means grading the pattern deliberately rather than scaling numbers. The constraints are covered in Plus size apparel in print on demand.

Material choices carry compliance weight. Fibre statements, recycled content claims and restricted substance limits all originate in the tech pack, and a specification without supporting documentation fails the first audit. Where a recycled material is involved, the paperwork needs to match the claim.

Then keep the file alive after launch. A change in supplier, a new trim or a revised care instruction updates the document, and the flagging works best through a single owner rather than a shared inbox. Assign that role before the second production run, and start your custom order today with a tech pack the factory can build from.
