Best Practices for Printing Clean Images
DPI stands for "dots per inch" and is the standard measure of printer resolution for digital imagery. Specifically, DPI refers to the number of dots of ink or toner that will appear within one square inch of the image when it is printed.
At Custom Ink, we recommend an image of 300DPI or more at actual print size to help ensure you get the very best print. Don’t have an image that meets that requirement? That’s ok! We will review your file and make adjustments for the best print.
Having trouble figuring out your image's DPI? On a PC, you can find this number by going to Start » Programs » Accessories » Paint, opening your image, and clicking on "Attributes" under the "Image" menu. If you have a Mac, open your image in Preview (your default image viewing program), and go to Tools » Inspector » Image DPI.
