How to onboard a design team on a merch project — 7-step playbook
Operating procedure so the marketing team, external agency or in-house studio gets on board on a corporate merch project in CDMX, Monterrey, Guadalajara or remote: creative brief, visual system, files, proofing, deliverables to the supplier and approvals.
What onboarding the design team actually means
Onboarding a design team is not sending a PDF with the brand and waiting for proposals. It is a structured process of visual, technical and operational alignment between the marketing team (or the brand), the design studio or agency, the merch supplier and the procurement team. Without this alignment, the files that reach the supplier have wrong typefaces, out-of-gamut colors, bad bleeds or insufficient resolution, and production gets delayed.
Scope of this article: onboarding 1 to 4 designers for a merch program of 300 to 20,000 units delivered to CDMX, Monterrey, Guadalajara, Querétaro, Puebla or any other Mexican city. It covers the creative phase (brief, exploration, proposals) and the technical phase (production files, color separation, color proofs, deliverables).
What this process is NOT: it is not just sharing the brand manual. The brand manual is one input, but the design team also needs the supplier's specifications (color chart, available substrates, technical limitations per technique: screen print, embroidery, sublimation, laser engraving, digital transfer). Nor is it just approving proposals. It is approving final files with a signed color proof and a technical sheet validated by the supplier.
The cost of good onboarding is measured in time saved. A design team that starts without a technical brief ends up generating 3-5 extra rounds of proposals and files that the supplier rejects for incompatibility. That is 2-4 weeks of delay and between 8% and 15% cost overrun for reprints and additional proofings. A structured onboarding costs 3-5 days and removes most of that risk.
The 7 steps to onboard the design team without rework
- Creative brief + technical brief in one document. The creative brief defines audience, tone, occasion of use and visual references. The technical brief defines SKUs, materials, print technique, sizes, logo positions, budget and deadlines. Both in one PDF signed by the brand lead and the procurement lead.
- Brand manual + supplier specifications. Brand manual with vector logo (AI, SVG, EPS), official typefaces (with license or download links), primary and secondary palette in HEX, RGB, CMYK and Pantone. Supplier specifications with substrate chart, available colors, technique limitations, maximum print widths, safe areas and forbidden zones.
- 90-minute alignment workshop. Session between design, brand and procurement to align expectations, review references, discuss technical restrictions and sign the timeline. Without this session, designers imagine creative freedom that the supplier cannot deliver.
- Validated source files delivered. Logo in AI/SVG with clean curves and fonts converted to outlines. Color palette with Pantone Coated and Uncoated where applicable. High-resolution photographs (minimum 300 DPI at final size) with documented rights assignment.
- First round of proposals with hard deadline. 3-5 proposals in low-resolution PNG/JPG for review. Brand team feedback consolidated in a single document (not scattered across 14 emails). Written approval before moving to final mockups.
- Physical or digital mockups validated with supplier. Digital mockups (Photoshop or platforms like Mockup World) or physical (printed textile sample by the supplier) before going to production. Supplier validation that colors and typefaces are viable in its substrate chart and equipment.
- Final files with color separation and signed proof. AI/PDF files with separated layers, cut marks, 3 mm bleed, fonts converted to outlines and colors in Pantone or CMYK by technique. Contract proof signed by the supplier before going to press.
Common mistakes that cost weeks
The first mistake is hiring the designer only for "the logo" and leaving them to design the entire visual system. The logo is 10% of the work in merch. The other 90% is adaptation to substrates, print techniques, positions, technical restrictions and product variants. Without a technical brief, the designer gets lost.
The second mistake is using RGB when the supplier needs CMYK or Pantone. RGB is for screens; merch colors are subtractive (CMYK) or spot (Pantone). A bad RGB→CMYK conversion produces opaque, washed or off-tone colors. Always use Pantone Coated for glossy substrates, Pantone Uncoated for matte substrates.
The third mistake is not licensing typefaces correctly. If the brand uses Gotham, Helvetica Neue or any commercial font, the designer must confirm the license covers use on physical products, not just digital. Without a valid license, the manufacturer can reject the file or the client can face a fine for unauthorized use.
The fourth mistake is approving mockups without seeing a physical proof. The digital mockup always looks better than the actual print. The physical proof (strike-off, printed or embroidered sample) is the only trustworthy reference. Without a signed proof, production arrives with wrong tones and reprinting is required.
The fifth mistake is forgetting a color variant. If the brand has a corporate blue, that blue must exist in versions for screen print (Pantone), embroidery (thread close to Pantone), digital print (CMYK) and laser engraving (ink or engraving by substrate). Sometimes the same blue cannot be achieved across all techniques and a variant must be approved.
The sixth mistake is delivering files without layers. The supplier needs to open layers to separate colors, adjust sizes and edit text in production files. Delivering a flat PDF is asking them to guess or redo, which costs person-hours and blocks the production line.
The seventh mistake is skipping supplier validation. The supplier must see and sign the final files before the brand approves them. This inverts the traditional order (brand approves first, supplier executes after) and removes the risk of the supplier rejecting the file once the PO is signed.
Tools, templates and references
Creative + technical brief template: 4-6 page document with target audience, occasion of use, tone, SKUs per product, quantities per size, print technique, total and per-unit budget, deadlines per milestone, visual references and regulatory restrictions (e.g. mandatory legends on corporate uniforms).
Final files checklist: AI or PDF with separated layers, fonts converted to outlines, 3 mm bleed, cut marks, palette in Pantone Coated/Uncoated and CMYK when applicable, embedded images at 300 DPI or vectors, packaged file with fonts and images folder.
Useful mockup platforms: Mockup World, Yellow Images, Smartmockups, Placeit. For physical mockups, request a printed strike-off or sewn sample from the supplier before production.
Regulatory references: NOM-026 on textile product labeling, LFPA and local regulations for mandatory legends on school uniforms, INDECOPI on advertising and copyright.
Realistic timeline from brief to approved final files: 12–22 business days for a 5-8 SKU collection. Add 5-7 additional days if a physical proof from the supplier is required.
Realistic design process cost: MXN 18,000–55,000 for a 5-8 SKU program with exploration, proposals, mockups and final files. Cost drops 30-40% when the design team already knows the brand and only updates variants.
