What Resolution Does a Logo Need to Be for Custom Safety Vest Printing?
A foreman once ordered a batch of hi‑vis vests for a highway project, only to discover the company logo looked like a pixelated smear when the crew walked onto the site. Within minutes the vests were sent back, the deadline slipped, and SafeWork NSW threatened a stop‑work order because the non‑conforming clothing didn’t meet AS/NZS 4602.1 visual‑identification requirements. The problem? The artwork was supplied at far too low a resolution.
Getting the logo right isn’t about making it look pretty – it’s about staying compliant, keeping workers visible, and protecting your brand’s reputation on the ground. Below we break down exactly what resolution you need, how to avoid the common pitfalls, and what the requirement means for everyday site work.
How Resolution Impacts Compliance and Visibility
Australian standards (AS/NZS 1906.4, AS 1742.3) demand that all reflective tape and graphic elements on a safety vest be clearly discernible from a distance of at least 30 metres. If the logo is blurry, a worker can’t be identified quickly, which defeats the purpose of hi‑vis clothing and can attract fines from WorkSafe Victoria or WHS Queensland.
In practice: A clear, sharp logo helps supervisors spot authorised personnel, assists emergency crews in locating team members, and ensures the vest still meets the minimum 50 mm tape width that must encircle the torso.

Minimum Resolution Requirements
| Printing Method | Minimum DPI* | Recommended DPI | File Type |
|---|---|---|---|
| Screen printing (most common for bulk orders) | 150 dpi (vector preferred) | 300 dpi | AI, EPS, PDF (vector) |
| Digital direct‑to‑garment (DTG) | 200 dpi | 400 dpi | PNG, TIFF (300 dpi minimum) |
| Sublimation (full‑colour) | 150 dpi | 300 dpi | PNG, JPEG (no compression) |
*DPI = dots per inch; a higher DPI yields finer detail. For logos, vector artwork (AI/EPS) is ideal because it scales infinitely without losing sharpness.
What this means on a real worksite: A 100 mm × 30 mm logo printed at 150 dpi will appear crisp on a Class R (roadwork) vest, even when viewed from a vehicle travelling at 80 km/h. Drop below that and the edges start to feather, making the logo indistinguishable and potentially breaching AS/NZS 4602.1, which mandates that any identification marking be legible at the prescribed viewing distance.
Practical Tool – Logo‑Readiness Checklist
- File format: Vector (AI/EPS/PDF) preferred; raster (PNG/TIFF) only if ≥300 dpi.
- Colour mode: CMYK for print; avoid RGB unless the printer confirms conversion.
- Resolution: ≥150 dpi for screen‑print, ≥300 dpi for DTG/sublimation.
- Size on vest: No smaller than 50 mm × 20 mm; maintain aspect ratio.
- Contrast: Logo colour must contrast with the vest’s fluorescent background (e.g., dark navy on yellow‑green).
- Brand placement: Central front or upper back, never covering reflective tape.
- Proofing: Request a physical sample or high‑resolution proof before the full run.
Where Sites Go Wrong
- Wrong vest class: Using a Class D vest for night‑time traffic control eliminates the reflective strip requirement, rendering the logo moot.
- Faded hi‑vis: Cheap imports often lose fluorescent intensity after a few washes, making even a perfect logo invisible.
- Cheap non‑compliant imports: Low‑cost overseas vests may ignore AS/NZS 1906.4 tape width, so the logo sits on a vest that already fails compliance.
- Incorrect branding placement: Some sites print the logo over the reflective tape, which defeats both branding and safety.
Industry Examples
Construction
A multi‑storey residential project required all site supervisors to wear custom Class D/N vests. By supplying a 300 dpi vector logo and positioning it on the upper left chest, the foremen could be identified instantly, cutting the time to locate a missing crew member after an incident by 30 seconds.
Traffic Control
During a night‑time road closure, the traffic‑control team used Class R vests with a 150 dpi screen‑printed logo on the back. The reflective tape surrounding the torso met AS/NZS 1906.4, and the clear logo prevented confusion with an adjacent contractor’s crew.
Warehousing & Logistics
A large distribution centre switched to custom fluorescent orange‑red Class D vests. By using a 400 dpi digital print, the internal safety team kept the logo legible even after 500 wash cycles, satisfying WHS Queensland’s durability expectations.
FAQ
Q: Can I use a low‑resolution JPG for a small logo?
A: Not advisable. Even a small logo must meet the minimum DPI requirement; otherwise it will appear blurry and may breach AS/NZS 4602.1.
Q: Do I need a separate logo for night‑time (Class N) vests?
A: No, the same high‑resolution artwork works for both Class D and Class N as long as the vest colour and reflective tape meet the relevant standards.
Q: How often should I replace hi‑vis vests?
A: Inspect them quarterly. If the fluorescent colour fades by more than 30 % or the reflective tape is damaged, replace them to stay compliant.
Staying on top of logo resolution isn’t just a design concern—it’s a safety imperative. By following the checklist, using the right file type, and observing the Australian standards, your custom safety vests will keep workers visible, your brand sharp, and your site free from costly compliance breaches.
