Reason:
In order to facilitate user typesetting, the image can be placed anywhere on the canvas. When printing, the software will automatically lock the image boundary and start printing from the place where there is an image in the canvas.

Solution:
The user can set the actual print position on the canvas in “Canvas Settings” -> “Canvas with White Edges at Output”.
The above method can solve the problem that the high-speed cylindrical bottle UV printer picture is placed in the middle of the canvas and printed on the edge.
