Tech Packs in Fashion: The Complete Production Blueprint

What’s a tech pack in fashion?

A tech pack, short for technical package, is a comprehensive document that serve as the blueprint for garment manufacturing in the fashion industry. It contains all the technical specifications and information necessary for a factory to accurately produce a garment accord to the designer’s vision. Think of it as the detailed instruction manual that bridge the gap between a designer’s creative concept and the manufacturer’s production process.

The importance of tech packs in fashion production

Tech packs play a crucial role in the fashion production process for several reasons:

Clear communication

they eliminate miscommunication between designers and manufacturers, peculiarly when work across different languages and cultures.
Quality control

they establish specific standards that manufacturers must meet, ensure consistency across production runs.
Cost efficiency

detailed tech packs reduce errors, minimize sample iterations, and prevent costly production mistakes.
Time management

they streamline the production process by provide all necessary information upfront.
Legal protection

they serve as contractual documents that outline incisively what has been aagreedupon between parties.

Essential components of a fashion tech pack

Technical flat sketches

At the heart of every tech pack are detailed technical flat sketches, besides call” flats ” r “” ds ” ” omputer aid designs ). )like fashion illustrations, these are precise, to scale, black and white line drawings that show incisively how the garment should look from multiple angles ( fro(, gage, and sometimes side views ). Th) display all construction details, include:

Seam placements
Stitch types
Hardware locations
Pocket placements
Postiche details
Closures (zippers, buttons, etc. )

These sketches must be clear, detail, and proportionately accurate, as they serve as the primary visual reference for the manufacturer.

Measurement specifications

This section includes a detailed measurement chart o” spec sheet” with precise measurements for each size in the production run. Measurements typically include:

Key body points (chest, waist, hip, etc. )
Length measurements (total length, sleeve length, iunseam etc. )
Circumference measurements (aarmholes leg openings, etc. ))
Placement measurements (pocket positions, logo placements, etc. )
Grade information (how measurements change between sizes )

Each measurement is typically provided in inches or centimeters, frequently with tolerance ranges( acceptable deviation) specify.

Bill of materials (bBOM)

The bill of materials lists all the materials and components need to produce the garment:

Fabrics

main fabrics, linings, interfacings, etc. With specific details on composition, weight, construction, and supplier information
Trims

buttons, zippers, hooks, elastic, ddraw cords etc.
Labels and tags

care labels, brand labels, hang tags
Packaging

polybags, hangers, boxes
Quantities

amount of each material need per garment

Each item in the BOM should include supplier information, material codes, color references, and any specific requirements or alternatives.

Colorway specifications

This section detail all color information for the garment:

Color swatches or physical color standards
Pantone color codes or other standardized color references
Color placements on the garment
Color combinations for different style variations
Approve color deviations (if any )

For prints or patterns, detailed artwork files and placement instructions are besides include.

Construction and sewing instructions

This section provides detailed instructions on how the garment shouldbe assemblede:

Seam types and finishes
Stitch types and stitch counts per inch
Thread specifications and colors
Special construction techniques
Assembly order and methods
Specific machinery requirements

Diagrams or close up illustrations ofttimes accompany these instructions to clarify complex construction details.

Labeling and packaging requirements

This section specifies:

Care label content and placement
Brand label specifications
Size label requirements
Country of origin label
Hang tag design and attachment method
Fold instructions
Packaging requirements (polybags, boxes, etc. )

Quality control guidelines

This critical section establish the quality standards for the production:

Inspection points and methods
Acceptable quality levels (aAQL)
Testing requirements (colorfastness, shrinkage, etc. )
Common defects to watch for
Sampling requirements

Reference images

Many tech packs include:

Photos of previous samples or similar styles
Detail shots of specific construction elements
Inspiration images for specific finishes or effects
Mood boards to convey the overall aesthetic
