Checking Print Sharpness Before Sending Artwork to Press
Before ordering custom stickers, ID badges, packaging labels, or passport prints measured in millimeters, enter your image’s pixel width and height into the calculator above at 300 DPI. If the resulting millimeter width is smaller than your physical print target, printing it larger will look soft unless you supply a higher-resolution original.
