The Gallery Wrap templates are a great help for printing on canvas to be wrapped around canvas stretchers. To respect frame depth and backside width of a wooden stretcher, the canvas requires an extra border for wrapping around. Otherwise parts of the image will go on the sides or back of the stretcher.
PrinTao 8 offers numerous options to set up these wrapping borders. The border width can be adjusted to the stretcher dimensions and there are several border types to choose from. Borders can have any single color or a stretched or mirrored part of the image.
