Dpi relates to the resolution and file size of a bitmap image. The higher the dpi, the higher a resolution you have.

If you were publishing an image on the web, it is common to use a file with a resolution of 72 dpi.

With printed materials, most presses print at a resolution of 300 dpi, although some go higher.

Why should you care?

If you send your printer a 72 d pi image, you may wind up with a low-quality image that is pixellated or has “artifacts.”

Conversely, if you try to publish a 300 dpi image to the web, it is going to be huge and you will probably have to scroll alot to see the whole picture. Not to mention it will take longer to load than a smaller picture.

Therefore, always keep in mind the purpose of your image before setting it to a certain dpi.

NOTE: If you have an illustration that is a low resolution, but you need to turn it into a high resolution, contact us and we will show you how or fix it for you.
