In canvas printing, the term "gallery wrap" refers to an image that appears on the sides of the frame as well as the front.
However, because the edges of the canvas are wrapped over the thick bars, approximately two inches of the image (top, bottom, and sides) are not visible from the front.
However, in some situations photo editing techniques are employed to fabricate additional image/material or to mirror existing content on the wrapped edges.
Gallery wrap production can be digitally automated with a Photoshop plugin or raster graphics editor.
The stretcher bars are often thinner, and the canvas can be secured at the sides with staples or tacks as the frame will hide them.
