Can I expect any distortion of print?

A balloon is inflated before printing, creating a curved surface so you may find that particular shapes (square, rectangle and circle) will distort on a fully inflated balloon. As each individual balloon inflates differently the distortion from one balloon to another may occur in different places. For example, the top right of a square may distort on one balloon and then the top left of a square may distort on another.
We try to keep this to a minimum and ask for your artwork within a 16cm square to try to eliminate this problem.
