How can I check to verify whether an image file can be used to make a high quality print?

An image is considered “print-ready” when it is:

  • A single layer (flattened) JPEG or TIF file format; ideally with an embedded color profile such as sRGB or AdobeRGB
  • Contains no special characters in the filename (#!^%$*@_/|:;’?, etc)
  • Has image dimensions of 300 or more dots per inch for the print size you desire (for best print quality), or no less than 150 dots per inch
