My artwork is blurry or doesn’t scale well when printed. Why?
Your image resolution may simply be too low. The recommended image resolution for printing is 300 dpi.
In Sketchbook Pro on desktop you can adjust your dpi in the Image > Image Size menu.
Sketchbook on mobile devices does not have a concept of measurement, therefore there is no set dpi. Your canvas is simply its pixel ratio, and the dpi that the canvas is printed at will be set by the printing method. If you are creating a piece to print, you will want to set up the canvas for the correct pixel dimensions when you start. For more information, see setting the maximum canvas size for printing.
