In order to print well, the image resolution of all graphics in your print files should be at least 300 dots per inch (dpi). Viewing images on a computer screen can be misleading, since the maximum image resolution of a computer screen is 72 dpi. A 72 dpi image will look fuzzy when printed.
Increasing the size of a graphic will reduce the resolution, while reducing the size of the graphic will increase the resolution. So, for instance, if you have a 300 dpi photo that is 2 inches by 3 inches and you enlarge it 200%, you have just decreased the image resolution from 300 dpi to 150 dpi. On the other hand, if you have a 72 dpi photo that is 8 inches by 10 inches and you reduce it to 2 inches by 2.5 inches, you have just increased the image resolution from 72 dpi to 288 dpi.
We often see individuals start with a 300 dpi photo and then enlarge it so much (especially on posters) that the image resolution becomes very grainy. The resolution of a graphic is for the original size. If you enlarge or reduce the graphic, you change the original resolution.
It is typically not a good idea to get graphics for print from a website. Most websites use 72 dpi photos so that the website will load faster.
If you are concerned about the image resolution of the photos and graphics in your print document, it is typically a good idea to get a hard copy proof before printing all copies of your file.
Following these tips will help ensure that you are dazzled with your printed document. We will check your files for some things, like proper bleeds, proper safety zones, and image resolution. We will notify you if there are problems, but that will likely delay your printing project while you correct your files. Other items we can’t check, such as whether you used the color you intended.
