A tech pack is the production instruction for your product. A well-made one puts the garment in the manufacturer's head and the garment in yours into the same shape. Where the pack is incomplete, the manufacturer fills the gaps with their own assumptions — and the sample that arrives is not the one you pictured.
Can production run without a tech pack? It can, but the process takes longer and needs more revision rounds. Without a pack the manufacturer works from a reference garment, images and verbal description, which leaves room for interpretation. If you are not bringing a pack, the sound approach is to build one together as the work proceeds.
What a tech pack contains
A professional pack covers the headings below. You do not need all of them — but the more you have, the faster the process runs.
The measurement chart is the critical part
The most commonly skipped and most decisive section is the measurement chart. "Size medium" on its own says nothing; every brand's medium is different.
Measurements should be given point to point: chest width, body length, shoulder width, sleeve length, cuff opening, neck width, hem width. Put a tolerance beside each one (say ±1 cm) — zero tolerance does not exist in textiles, and without a stated tolerance what counts as acceptable stays arguable.
If you own a garment you like, that is the most practical route: measure it into the chart, or simply send it as a reference.
How to specify colour
Colour is where the gap between what you see on screen and what comes out of the dye house is widest. Every screen renders colour differently, and a word like "navy" covers dozens of shades.
Where possible give a Pantone TCX code (the textile set). If you have no Pantone reference, send a physical colour sample — a piece of fabric, a thread, even a garment you like. A physical reference always beats a verbal description.
Approve colour physically at the sample stage as well; never sign off a colour from a screenshot.
Sending artwork correctly
Artwork files are a common source of delay. Three points matter:
Prefer vector. AI, EPS or PDF vector files scale to any size without loss. JPG and PNG degrade when enlarged.
If you must send a raster file, send it at high resolution. At least 300 dpi at the real printed size.
State placement and size. Something like "centre chest, 8 cm below the neckline, 25 cm wide". Sending the file is not enough on its own; where and how large it prints must be written down.
What to do if you have no pack
Most brands do not arrive at their first production with a tech pack, and that is not a problem. Any one of the following is enough to start:
Frequently Asked Questions
Do you prepare the tech pack?
Yes, we can support that. Working from a reference garment, images or sketches, we build the measurement chart and technical details with you. The pack sharpens as the process moves and takes its final form at sample approval.
Do I have to send a reference garment?
Not required, but it is the fastest route. A physical garment communicates the hand of the fabric, the fit of the pattern and the stitching details with a clarity no description matches.
Which unit should I give measurements in?
Centimetres are the common standard and cause the least confusion. If you use inches, state it explicitly on the chart — a mix-up in units can cause serious errors in production.
Does everything in the pack have to be final?
No. Open points get settled during sampling. What matters is that the things you are certain about are recorded correctly, and that the uncertain ones are known to be uncertain.
