Resolution is the degree of detail visible in a raster or vector image.
For more information, check out our video tutorial or continue reading below:
Raster images (like photos) are comprised of pixels — or, dots of colour.
- High resolution means there are many dots per inch.
- Low resolution means fewer dots per inch, and poorer quality.
- For Vistaprint products, aim for at least 300 dpi at the desired image size unless the product indicates otherwise.
Vector images are not comprised of pixels; they are calculated and displayed with the help of mathematical equations.
- They can be stretched to any size while maintaining high quality.
- It is preferable to use vector images whenever possible.
