Tech-pack

A Tech-pack is a technical description manual of a garment design for clothing manufactures. They need a tech-pack in order  to make a prototype of the design. These prototypes are also called ‘Samples’ or ‘Salesman samples’. Tech-packs are generally made by fashion designers, technical designers and product developers.

Components in a Tech-pack
Clothing manufacturing is a long and elaborate process, in which many components have to be developed such as; fabrics, prints, patterns, buttons, zippers, cords, labels, etc. All these elements and details have to be explained in a Tech-pack, in order to get an accurate sample.

The fit
An important aspect of a sample is the fit. To get the right fit, a Tech-pack must include a measurements chart. These measurements charts are also called, ‘Specs’ or ‘Size specs’.

International format
In this article, I’ll explain ‘my Tech-pack format’ that I’ve developed over the years. My format is compact and easy to understand. With my Tech-packs, I’ve created menswear and women’s collections at clothing manufacturers in; Europe, The Middle East and The Far East.

Stylesheet

A design is also called a ‘Style’. The purpose of a ‘Stylesheet’ is to explain the look and feel of the design. At this page, I’ll put a full-colour drawing including the intended Pantone colours and codes. I use predominately the Pantone’s Textile Colour System. At the left top of the frame, I’ll put the intended collection season and the name of the design. At the right top of the frame, I’ll put the colourway of the design. In the column at the right, I’ll put the information about the components, I want to be used in the designs such as; fabrics, trims, artwork, labels etc. These components are also called BOM (Bill of Material).

 

 Description sheet

Drawings can be interpreted in different ways. Therefore a ‘Description sheet’ is essential in a tech-pack. In a ‘Description sheet’, all components of a design should be explained, as well the drawing techniques should be exemplified. For example, a dotted line. If fashion designers want to illustrate stitching, they often use dotted lines. But a dotted line in a drawing could also mean something else entirely. For example, a dotted print. Therefore a well thought out ‘Description sheet’ is essential in the process of creating an accurate sample.

 

Size specs

example-tech-pack-description-size-spec

A Size spec is a measurement chart specifically created for pattern cutters/pattern makers. Pattern cutters will make a pattern based on the measurements listed in a Size spec. These patterns will be used to make a sample.

In a Size spec, all measurements such as the front length, chest width and the shoulder length of a garment must be listed. I’ll always put a small black and white drawing on the left side of the page to make it more visual for the pattern cutter and, I’ll point out more difficult to understand measurements with red arrows.

The regular measurements such as the chest width, I’ll only put in the right column. At the right top of the frame, I’ll put the sample size. I’ll always include a guidelines sheet of how I measured in my Tech-packs to avoid confusions. This guidelines sheet is also called ‘POM sheet’ or ‘POM’s sheet’ (Points of Measurement sheet).

You must at least have a basic understanding of pattern cutting and clothing making if you want to create a precise Size spec. I studied pattern cutting and clothing making for over 6 years in The Netherlands and, I’ve worked for a tailor.

I studied 2 years pattern cutting and clothing making at a Technical School for Fashion in Amsterdam and I studied 4 years pattern cutting and clothing making at ArtEZ University of the Arts.
