The tech pack
A specification, not a description — and the distinction is real.
The pack keeps three kinds of statement apart, and knowing which is which tells you where to look first.
Measured
The garment's extent in the frame, artwork sizes and placements, colour sampled from the actual pixels. These are taken from the images rather than estimated.
Assumed
Real-world width comes from the garment category's size chart until a point of measure overrides it. The pack flags this rather than hiding it.
Specified
What you chose. Requirements the pack must state, which win over what a picture appears to show.
What to check
Everything is editable, including the name in the header, and points of measure grade automatically from the base size. The parts worth your eye are the ones the studio cannot know: country of origin, which defaults until you set it, and print method, Pantone codes and fibre content, which are the model's best reading of your images.
