- List required markings
- Define fixed placement zones
- Use readable contrast
- Document every unit
Why this matters for commercial fleets
A decision that seems minor on one vehicle can become expensive when repeated across a fleet. Clear specifications, photographs, approvals, material records, and installation notes reduce rework and make future additions easier to manage.
Use a documented process
- Identify the exact vehicle and operating requirements.
- Inspect surfaces, equipment, existing graphics, and modifications.
- Approve vehicle-specific artwork and written specifications.
- Coordinate production and installation with fleet operations.
- Archive final files, materials, colors, and completion photos.
