How to Design a Custom Cap: Tech Pack & Artwork Guide
12 min read
Everything you need to design a production-ready custom cap, from choosing construction and decoration to preparing artwork files a factory can actually use.
Designing a custom cap means making three linked decisions, construction (the blank cap itself), decoration (how your branding is applied), and artwork files (what you send the factory), then recording them in a tech pack. Get those three right and sampling is fast and accurate. Get them vague and you will burn cycles correcting a sample that was never properly specified. This guide covers each decision and shows exactly how to prepare artwork a factory can use.
Part 1: Choose the construction
Construction is the physical cap your branding sits on. The main variables are:
- Panel count: five or six panels are most common. A 5-panel cap gives a flat front face ideal for a single bold logo, while six-panel styles suit balanced embroidery.
- Crown structure: structured crowns hold their shape with buckram or foam; unstructured crowns sit soft and low.
- Brim: flat, pre-curved, or fully curved, with variable stiffness.
- Closure: snapback, strapback, buckle, elastic fit, or fitted sizing.
- Fabric: cotton twill, canvas, performance polyester, corduroy, or specialty textiles.
Choose construction based on how the cap should feel and what branding it must carry. A structured baseball cap showcases a raised 3D front logo; a soft performance flexfit cap suits flat embroidery and an athletic market.
Part 2: Choose your decoration
Decoration is where your brand lives. Each technique has a distinct look and ideal use:
| Technique | Best for | Notes |
|---|---|---|
| 3D puff embroidery | Bold raised front logos | Foam under stitch creates height; keep shapes simple |
| Flat embroidery | Most logos and lettering | Durable, classic; min character height around 5mm |
| Woven patch | Fine detail, small text, gradients of colour blocks | Holds detail embroidery cannot |
| Leather / PVC patch | Premium or outdoor branding | Debossed leather or moulded PVC |
| Chenille patch | Varsity, textured letters | Soft raised pile |
| Screen print | Flat graphics, large coverage | Best on flat panels |
| Dye-sublimation | All-over or photographic colour | Works on polyester fabric |
Match the technique to the artwork. Tiny text and gradients belong on a woven patch or sublimation, not flat embroidery. Bold simple marks shine in 3D puff.
Part 3: Prepare your artwork
This is where most delays start. Follow these rules:
- Send vector files. AI, EPS, or layered PDF, with fonts converted to outlines so nothing reflows on another machine.
- Specify Pantone solid coated colours for every element so thread, dye, and print can be matched and repeated.
- Simplify for embroidery. Remove hairline strokes and tiny gaps that will not stitch. If the mark is complex, plan a patch.
- Provide placement and size. State logo position (front centre, left panel, back, side) and finished dimensions in millimetres.
- Include a mock-up. A simple visual of each decoration on the cap helps everyone align before stitching.
Part 4: Write the tech pack
The tech pack combines everything above into one reference document. A complete cap tech pack includes:
- Silhouette and panel count
- Crown structure and height
- Brim shape and stiffness
- Closure type
- Fabric, lining, and sweatband
- Each decoration with technique, placement, size, and Pantone colours
- Attached vector artwork and a visual mock-up
Hand this to the factory and your first sample will be far closer to right the first time.
Design for manufacturability
A design that looks great on screen can be hard to build. Keep these constraints in mind: embroidery cannot reproduce photographic detail; very small text stitches poorly; seams interrupt large flat prints; and 3D puff works best with bold, closed shapes. When in doubt, pick the decoration technique first and design the artwork to suit it, rather than forcing an unsuitable technique onto a finished graphic.
Key takeaways
- Design is three linked decisions: construction, decoration, and artwork.
- Vector files with Pantone references are the fastest route to an accurate sample.
- Match the decoration technique to the artwork, fine detail goes on patches, bold marks on puff.
- A complete tech pack with placement and sizes removes guesswork during sampling.
- Design for how caps are actually built, not just how the graphic looks on screen.

Frequently asked questions
What file format should I send for cap embroidery?
Send vector artwork, ideally AI, EPS, or PDF, with text converted to outlines. Vector files scale cleanly and let the factory digitise an accurate embroidery file. A high-resolution PNG can work as a reference, but a flattened low-resolution image slows digitising and risks detail loss.
How small can text on a cap be and still read?
As a rule of thumb, embroidered lettering should be at least about 5mm tall per character so individual letters stay legible. Very fine detail stitches poorly; if your logo has tiny text, consider a woven or printed patch instead, which holds fine detail far better.
Do I need to specify Pantone colours?
Yes. Naming Pantone (solid coated) references removes ambiguity for embroidery thread, fabric dye, and print. Without them, colour is matched by eye and may drift between runs. Pantone references make your brand colours repeatable across future reorders.
Can you help if I only have a rough logo?
Yes. During sampling our team refines embroidery and patch files so they stitch cleanly, adjusting stitch density, underlay, and small details. You still get the best result by supplying clean vector artwork, but we will work with what you have.
