Canvas Printing and Stretching
The purpose of stretching a canvas is to preserve it and prepare it for framing. We stretch a lot of canvases, both painted and unpainted. Depending upon the size of the canvas, we have 3 different sizes of wood stretcher bars we use.
We also believe in using cross bars to prevent canvases being stretched from developing an hourglass shape.
We usually use pneumatic staplers and can either staple the canvas on its edge or on its back, depending upon how much canvas we have to work with.
We prefer to have at least 1" beyond the amount of canvas it takes to cover the edge of the stretcher bar. That way, we have something to grab with the canvas pliers so that we can stretch the canvas tightly with a minimum of wrinkles.
This means we prefer 2-3" from the edge of the painting. In that way, we can staple the canvas on the back. If you are stretching on a 1 -1/2" to 2" deep Gallery Wrap stretcher, you will need an extra 2 -1/2" to 3" all around.
Typically, the longest, heavy duty stretchers we build can be just under 10 feet long. We buy heavy duty stretcher bar in 10 foot sticks. You must allow for miters at the corners, so the stretchers cannot be 10 feet long.
