Image resolution

If you are using images in your design, make sure you are using the correct resolution. The resolution [resolution: The fineness of detail that can be seen in an image - the higher the resolution of an image, the more detail it holds. It is measured in dots per inch (dpi). ] of an image is measured in dots per inch (dpi), also known as pixels per inch (ppi). The dpi determines the amount of detail the image has.

If the final image is to be displayed on a computer (web/CD-Rom etc), the resolution should be 72-96 dpi. If the final image is in print, then it is usually best to set the dpi to the highest number you can - around 300 dpi. If you wish to enlarge an image to be used on the web or for print, always scan it at the highest dpi you can, and then enlarge the image size in your graphics software (eg Photoshop). You can then save it to the appropriate file format.
