Resolution, also known as DPI (Dots Per Inch) or PPI (Pixels Per Inch), can be described as the number of dots that fit horizontally and vertically into a one-inch space. Generally, the more dots per inch, the more detail captured and the sharper the resulting image.
- Images designed for the web are usually at a low screen resolution of 72 dpi and are not suitable for printing purposes. Print images need to be created at 300 dpi or there will be a substantial drop in the image quality.
- Photo or raster images must have a resolution of 300 dpi.
