Best Practices for Communicating Design Details Through Tech Packs
Creating a tech pack is one of the most crucial steps in turning your fashion design from concept to reality. It’s the bridge between your creative vision and the manufacturer who will bring that vision to life. A well-structured tech pack contains all the technical details of your garment design—materials, measurements, construction methods, and quality control requirements—ensuring that the final product meets your expectations.
However, to ensure clarity, avoid miscommunication, and streamline the production process, it’s essential to follow best practices when creating and communicating design details through your tech pack. In this article, we’ll outline the key best practices to follow when creating and sharing your tech pack.
1. Use Clear, Detailed Visuals
Visual representation is key to communicating your design to the manufacturer. Words alone can’t always capture the nuances of your creative vision, so clear and detailed visuals help ensure accuracy.
Best Practices:
- Flat Sketches: Include flat sketches or technical drawings that show the garment from multiple views (front, back, and side). These sketches should indicate key design features such as stitching, trims, and any additional design details like pleats, folds, or embroidery.
- Detail Close-ups: For intricate design features (such as buttons, zippers, or embroidery), include close-up drawings or photos. Label these details clearly to avoid any ambiguity.
- 3D Renderings: If possible, use 3D design software like CLO 3D or TUKAcad to provide digital renderings of your designs. These realistic visualizations help manufacturers understand how the garment should look and fit.
- Color Palettes and Fabric Swatches: Include fabric swatches or detailed images of the materials you’re using. Ensure you include the Pantone color codes or other standardized color references for consistency.
Why It Works:
Visuals break down the complexities of your designs, leaving little to interpretation. They reduce errors and create a clearer, more accurate communication channel between you and the manufacturer.
2. Provide Detailed Measurements and Size Charts
The fit and sizing of your garment are crucial for customer satisfaction. Tech packs should include detailed measurements for every size, specifying the dimensions for key areas such as chest, waist, hip, inseam, and body length. This ensures that the manufacturer produces garments that meet the correct sizing standards.
Best Practices:
- Size Charts: Include a detailed size chart for all the sizes in your collection (e.g., XS, S, M, L, XL, etc.), listing key measurements for each size, such as bust, waist, hip, inseam, and length.
- Grading Rules: Specify how measurements should be adjusted across different sizes. This ensures that the garment fits consistently across all size ranges. For example, a size M might have a chest measurement of 38 inches, and a size L might increase by 2 inches.
- Tolerance: Include acceptable tolerance ranges for each measurement (e.g., “chest measurement tolerance: +/- 0.5 inches”).
Why It Works:
Accurate measurements and clear grading rules ensure that the garment fits as intended across different body types, reducing the likelihood of sizing issues during production.
3. Specify Fabric and Material Details
The choice of fabric and materials impacts the overall look, feel, and durability of the garment. It’s essential to be very specific about the fabrics used in the design to avoid misunderstandings.
Best Practices:
- Bill of Materials (BOM): List all materials required for the garment, including the type of fabric, trims, zippers, buttons, threads, and labels. Include the fabric composition, weight, and texture (e.g., 100% cotton, 200 GSM).
- Swatches and Color Codes: Attach fabric swatches or provide high-quality images of the fabric to ensure that the manufacturer uses the correct material. Use Pantone color codes for fabric and trim colors to avoid color mismatches.
- Fabric Testing Details: If applicable, specify any fabric testing requirements, such as shrinkage tests, abrasion resistance, or color fastness tests.
Why It Works:
By detailing every material and color in the tech pack, you prevent mistakes in sourcing, ensuring that the right fabrics and trims are used, and that the garment performs as expected.
4. Define Construction Methods and Techniques
The construction of a garment plays a major role in its quality and fit. The tech pack should outline how the garment should be constructed, from stitching to seam types, ensuring that the garment is made to the designer’s standards.
Best Practices:
- Stitching and Seams: Specify the type of stitching and seams that should be used (e.g., double-needle stitching, French seams, overlock) and their placement on the garment.
- Construction Notes: Provide detailed instructions for unique construction techniques, such as pleating, quilting, or piping, to ensure these details are executed correctly.
- Finishing Details: Detail any finishing processes, such as edge finishes, hem types (e.g., rolled hem, blind hem), and any extra steps that should be taken (e.g., pre-washing the fabric).
Why It Works:
Clear construction instructions minimize the chance of errors during production, ensuring that the garment is assembled according to your specifications, leading to better quality and fewer mistakes.
5. Incorporate Quality Control Guidelines
Quality control is an integral part of the manufacturing process. By setting clear quality standards and expectations, you ensure that the manufacturer understands how to inspect and test the garment for defects or inconsistencies.
Best Practices:
- Inspection Points: Identify specific areas of the garment that need close inspection (e.g., stitch quality, fabric defects, color consistency). This ensures that the garment meets your quality standards at every stage.
- Tolerance Levels: Specify the acceptable tolerance for things like fabric defects, measurements, and stitching. For instance, you might accept a slight imperfection in the fabric, but only within a certain size.
- Testing: If necessary, include fabric or garment testing requirements, such as stretchability tests, washing tests, or shrinkage testing.
Why It Works:
Setting clear quality standards and testing requirements in the tech pack ensures that the manufacturer knows exactly how to check for and fix potential issues, leading to higher-quality garments and fewer defects.
6. Set Clear Packaging and Shipping Guidelines
The final part of the process—packing and shipping—can also benefit from clear instructions. By specifying packaging requirements, you help ensure that the garments are handled correctly and arrive in perfect condition.
Best Practices:
- Packaging Instructions: Specify how the garment should be folded, hung, or packed (e.g., “folded with a hang tag attached, packed in a biodegradable polybag”).
- Labeling: Provide instructions for product labeling, including the placement of care labels, size labels, and brand tags.
- Shipping Requirements: Include details on how the garments should be packaged for shipping, including any specific labeling for cartons or boxes.
Why It Works:
Clear packaging and shipping instructions ensure that the garments are handled correctly, reducing the risk of damage during transportation and ensuring that they meet your brand’s standards when they reach the customer.
7. Collaborate and Communicate Efficiently
A well-organized tech pack allows for seamless collaboration between designers, manufacturers, and other stakeholders. Clear, organized documentation ensures that everyone is on the same page and can easily access the details they need.
Best Practices:
- Collaborative Platforms: Use platforms like Techpacker, CLO 3D, or Google Drive that allow for real-time collaboration and easy updates to tech packs.
- Feedback Loops: Set up structured feedback loops with manufacturers and other team members to discuss any issues or revisions, ensuring smooth and efficient communication.
- Version Control: Keep track of different versions of the tech pack to ensure that the latest changes are reflected in all documents shared with manufacturers.
Why It Works:
Efficient collaboration reduces the chances of errors and delays, making the entire process more streamlined and transparent. A tech pack that is easy to update and collaborate on ensures that all stakeholders are aligned and can work together toward the same goal.
