We recommend 300 ppi at the size ordered for best print quality.
The image file size can vary depending upon page design or print size. For example, when printing a 6x8 image in landscape with one image on one side of the pano, the resolution of that image needs to be 1800x2400 ppi.
However, if the image spans across the pano of a 6x8 photobook, the recommended resolution is 1800x4800 ppi.
To calculate the file resolution needed for different sizes, take each dimension of the print size and multiply by 300. For example, when printing an image as a 16x24, the ppi should be 16x300=4,880 and 24x300=7,200 for a ppi of 4,880x7,200.
If an image is too low resolution for a layout, Zno’s software will show an alert (an orange circle with an exclamation point at the bottom left hand side of the image).
