In order to ensure vivid imagery with true-to- life colors your photos should be high-quality, or high-resolution. High-resolution images deliver the best results when printed, ensuring your print will look stunning. Low quality images oftentimes look fine on the screen of a computer or smartphone, but this low quality becomes apparent when printed because there is a lack of detail. Sometimes it is necessary for our design team to scale your file to the appropriate size based on the final size of the print, so it is important to have the highest quality image possible to start.
Understanding Image Resolution
Image resolution is measured by the number of pixels per inch, or ppi. The higher the density of pixels, or rather the more pixels there are in an inch, the higher the resolution. You should select photos that are 300 ppi or higher. Anything less than 300 ppi will appear blurry, or pixelated, when printed. Digital cameras measure image resolution by the number of horizontal pixels by vertical pixels. This may look like 1290 x 960 or 1200 x 1800. The higher these numbers are the higher the resolution, but ppi is the best way to determine the quality of an image you want to have printed.
Selecting the Best File Type
Ideally, your image should be a JPG, .TIF or .EPS file. These file types support high-resolution images and will print nicely. Generally, .GIF and .PNG files are not of a high enough quality to use for printing, so we suggest you not use files in this format.
How to Find the Type and Resolution of Your File
If you are trying to determine what type of image you have and the resolution of the image find the file on your computer or laptop. Right click on the file and select Properties (PC) or Get Info (Mac). From there you can follow the prompts to confirm the resolution and file type.
