What are vector and pixel graphics?
Vector graphics

Vector graphic
The image represented by a vector graphic is composed from geometric forms like points, lines, circles or curves.
The image displayed is mathematically defined using these geometric forms. This is how a vector graphic can be enlarged (scaled) without a loss of quality, as the image is recalculated each time the size is changed.
Vector graphics can be created with graphics software like Adobe Illustrator, Corel Draw or Inksape.
Vector graphics serve as the master copy for plot printing (flex and flock) at Spreadshirt. In order to ensure the highest compatibility, please save your vector graphics in the format .ai.

Pixel graphic
A pixel graphic is a computer graphic in which the image is represented by raster forms made up of pixels (points of colour.) Each pixel represents one colour.
When a pixel graphic is enlarged, the individual pixels are also enlarged. Therefore, the more the image is enlarged, the more it will look coarse, angular or “pixellated”.
Pixel graphics serve as the master copy for digital printing at Spreadshirt. We recommend saving pixel graphics in the format .png. A graphic’s resolution is given in dpi and represents the number of dots per inch.
