A poorly completed tech pack is the single most common cause of sampling delays, off-specification production, and post-shipment quality disputes. Most buyers send a factory a description of what they want — in an email — and are surprised when the sample doesn’t match their vision. A proper umbrella tech pack eliminates ambiguity before production starts and gives you contractual standing to reject goods that don’t meet specification. We review tech packs from buyers every week, and this is the complete field-by-field guide with a template you can complete directly.

A tech pack is a technical specification document that defines every measurable attribute of the product you want to manufacture. A tech pack is not: a mood board, an email description, a photograph of a competitor’s product, or a sales catalogue image.
The practical test: If two different factories each received your tech pack independently, would they both produce the same sample? If the answer is no, the tech pack is incomplete.
CANOPY DIMENSIONS Canopy span (open, across diameter): _______ cm Number of panels: _______ Number of ribs: _______ Canopy height (closed): _______ cm FABRIC Fabric type: [ ] Polyester pongee [ ] Nylon pongee [ ] rPET [ ] Other: _____ Fabric weight: _______ GSM Colour reference: Pantone _______ (or: match approved swatch) DWR coating: [ ] Required [ ] Not required DWR chemistry: [ ] PFC-free C6 [ ] Fluorine-free [ ] Other: _______ PRINT Base canopy colour: Pantone _______ / approved swatch #_______ Colour tolerance: ΔE _____ (recommended: ≤2.0) Print method: [ ] Screen print [ ] Sublimation [ ] Digital [ ] None Print panels: Panel numbers _______ Print colour(s): Pantone _______ Logo position: _______ mm from canopy edge / _______ mm from rib seam Logo size: _______ mm wide × _______ mm tall
DWR note for UK/EU market: C8 (PFOA-containing) DWR is banned under EU REACH Regulation Annex XVII. If you don’t specify DWR chemistry, you may receive a non-compliant product. Always specify PFC-free C6 or fluorine-free.
RIBS AND STRETCHERS Rib count: _______ Rib material: [ ] Steel (gauge: _____) [ ] Fibreglass [ ] Aluminium Rib length: _______ mm Stretcher material: [ ] Steel [ ] Fibreglass [ ] Aluminium SHAFT Shaft type: [ ] Single-section [ ] Telescopic (sections: _____) [ ] Folding Shaft material: [ ] Steel [ ] Aluminium [ ] Wood [ ] Fibreglass Shaft length (closed): _______ mm Shaft length (open): _______ mm Shaft diameter: _______ mm Shaft finish: [ ] Painted [ ] Powder-coated [ ] Chrome [ ] Natural RUNNER AND TIP Auto-open mechanism: [ ] Required [ ] Not required Auto-close mechanism: [ ] Required [ ] Not required Tip type: [ ] Metal [ ] Plastic cap [ ] Rubber tip Tip cap pull test: _______ kg minimum
For promotional umbrellas, 3.0mm steel rib is standard. For golf umbrellas in coastal or high-wind use, fibreglass ribs at 3.5–4.0mm are the correct specification. If you don’t specify, most factories default to the cheapest option available.
Handle type: [ ] Crook [ ] Pistol grip [ ] Straight [ ] C-hook Handle material: [ ] Rubber (TPR) [ ] ABS plastic [ ] Solid wood [ ] Acrylic Handle colour: Pantone _______ / match wood grain / transparent Handle length: _______ mm Handle attachment: [ ] Adhesive [ ] Screw-fit [ ] Moulded-on Pull test load: _______ kg minimum (recommended: 15 kg for 10 seconds) Custom moulding: [ ] Required (tooling applies) [ ] Standard stock handle
Custom handle colour via injection moulding: tooling typically $500–$2,500, requires MOQ 1,000+. Below that, use a stock handle from the factory’s standard range.
This is the section where most tech packs fail. Without explicit print specifications, colour accuracy and logo placement are matters of interpretation — which means they vary by operator, shift, and production run.
Print method: [ ] Screen print [ ] Sublimation [ ] Digital [ ] Embroidery Pantone reference(s): PMS _______, PMS _______, PMS _______ Colour tolerance: [ ] Pantone ±1 shade [ ] ΔE ≤2.0 [ ] ΔE ≤3.0 Logo position: _______ mm from canopy edge / _______ mm from rib seam Logo panel(s): _______ (e.g., panels 1,3,5,7 or all 8 panels) Ink type: [ ] Water-based [ ] Plastisol [ ] UV-cured Ink adhesion: [ ] ISO 2409 Grade 0–1 [ ] Not specified Strike-off approval: [ ] Required on production fabric before run [ ] Not required
Strike-off: Requiring a strike-off approval on production fabric adds 5–7 business days but eliminates colour disputes before 1,000 units are printed incorrectly.
Carry bag: [ ] Required [ ] Not required Carry bag fabric: [ ] Polyester [ ] Nylon [ ] rPET [ ] Canvas Carry bag closure: [ ] Drawstring [ ] Zipper [ ] Velcro Carry bag print: [ ] Required [ ] Not required Wrist strap: [ ] Required [ ] Not required Label type: [ ] Woven [ ] Printed [ ] Embossed [ ] None Care instructions: [ ] Required [ ] Not required Country of origin label: [ ] Required [ ] Not required
This is the section that gives you contractual standing to reject non-conforming goods. Without it, you’re negotiating from a weaker position on any quality dispute.
AQL STANDARD Inspection standard: ISO 2859-1, Normal Inspection, Level II Critical defects: Zero tolerance Major defects: AQL _______ (recommended: 2.5) Minor defects: AQL _______ (recommended: 4.0) ACCEPTANCE CRITERIA Canopy colour: ΔE ≤ _______ vs approved sample Print position: ± _______ mm from specified position Seam stitch count: _______ stitches/cm Canopy span: ± _______ cm of specified dimension Shaft length: ± _______ cm of specified dimension Tip cap pull test: _______ kg — shall not dislodge Handle pull test: _______ kg — shall not separate from shaft APPROVED SAMPLE Approved sample reference: Sample ID _______, date approved _______ Inspection timing: Pre-shipment, goods ready to pack Inspector: [ ] SGS / Intertek / Bureau Veritas [ ] Factory QC + photo report Reject action: Batch held pending buyer written approval

Real project — anonymised
A promotional products distributor sent us a tech pack for a 1,000-unit golf umbrella order. Two pages. It specified canopy size, rib count, colour, and logo. What it omitted: rib material, shaft length, handle pull test, carry bag specification, approved sample reference.
The factory produced to the specification as written — which they interpreted as a budget promotional golf umbrella because the tech pack contained nothing indicating otherwise. The buyer expected a prestige golf specification.
The issue wasn’t the factory. The tech pack didn’t communicate what the buyer wanted because it only specified what the buyer thought to specify.
Check 1: Does every dimension have a unit (mm or cm)? A measurement without a unit is unusable.
Check 2: Is every colour reference a Pantone number or an approved swatch? “Red” is not a specification.
Check 3: Does the quality section specify AQL level, tip cap pull test, and an approved sample reference number?
Check 4: Is the DWR chemistry specified if the product goes to UK or EU market?
Check 5: Does the carry bag have its own print specification, or is it assumed to be plain?
In our experience across 900+ projects, the most common tech pack failure is treating the quality section as optional. It isn’t — it’s the section that determines whether you can reject non-conforming goods.
A complete umbrella tech pack covers seven sections: canopy specification (dimensions, GSM, colour, print method), frame specification (rib material, shaft type and length), handle specification (material, pull test), print/branding (Pantone references, ΔE tolerance, strike-off requirement), accessory specification (carry bag), quality standard (AQL level, approved sample reference), and packaging specification (carton count, dimensions).
Start with the functional requirements — what does the umbrella need to do, and who uses it? Then work backwards. “It needs to survive coastal wind” → fibreglass ribs. “It needs to match our brand colour” → specify Pantone reference and ΔE tolerance. Use the template structure in this guide and fill each field in sequence. For any field you’re unsure about, ask the factory for their standard specification and review whether it meets your needs.
A photograph alone is not a tech pack. You can include reference photographs alongside a tech pack, but the photograph doesn’t specify dimensions, materials, GSM, colour tolerances, or quality standards. A factory that samples from a photograph alone will produce something that looks like the image — but the materials, construction, and quality level will be whatever the factory defaults to, not what you want.
ΔE (Delta E) is a numerical measure of colour difference. A ΔE of 0 is a perfect colour match. For professional brand colour matching, ΔE ≤2.0 is the accepted standard — at this level the difference is barely perceptible to a trained eye. Without specifying ΔE tolerance, “match my brand colour” is interpreted differently by every operator and factory.
A strike-off is a printed sample on the actual production fabric roll, produced before the full print run starts. It confirms colour, ink adhesion, and print registration on the production fabric match your approved specification. Colour behaviour varies between test fabrics and production fabrics. Requiring a strike-off approval adds 5–7 business days but eliminates this entire class of colour dispute.
If you’re placing a custom umbrella order and haven’t completed a formal tech pack, the most important step is doing this before your first contact with a factory — not after you’ve reviewed a counter-sample.
Zeelyne works with buyers at every stage of the specification process, including completing or reviewing tech packs before sampling starts. Our custom umbrella manufacturing programme is designed for buyers who want to specify correctly the first time. Review our quality capabilities and certification documentation including our standard AQL protocols and approved sample process, or browse our full product range to identify the closest base specification.
Share your brief or your existing tech pack — we’ll review it and flag any gaps before production starts.
