Vector vs. Raster
Vector files are made of mathematical paths and shapes - they scale to any size without quality loss. Logos and illustrations should always be vector. Raster files are made of fixed pixel grids - they have a maximum sharp size set by their resolution and pixel dimensions. Photographs are inherently raster.
Why it matters for your project
For large format, always supply logos as vector (AI, EPS, SVG). Supply photographs at high resolution sized for final output (100–150 dpi at final size). The single most common file-prep mistake is supplying a low-res raster logo - the wrap looks blurry and there's no way to fix it without re-creating the artwork in vector.
