As we discussed on the Services page of our website, we digitally “stretch” our image before wrapping it around the edge of our gallery-wrapped canvas images. Here’s how we do that:
Our gallery wraps are either 3/4” thick or 11/2“. On the thin ones, I usually take the 1/4” strip along the edges and stretch it to 1″, thus having an extra 1/4” to wrap around to the back side to cover for variations in the printing and stretching processes. On the larger ones, I take 1/2” and stretch it to 2″ (thus leaving 1/2” on the back). I wouldn’t stretch the image more than four times its original size, but you could go less. To do that, you would effectively be taking a wider margin to wrap around the side.
As an example, if I want a 12” x 18” image stretched around a 11/2” frame, I would crop the image to 13” x 19”. Then, after putting guides 1/2” in from each edge and another guide right on each edge, I would increase the canvas size 3” in both dimensions to get 16” x 22” with the image centered.
- Click Image ⇨ Canvas Size…
- Put a check in the Relative Box
- Make Width and Height 3 Inches
- Make sure Anchor dot is in center of the grid
- Hit OK
- Make sure Snap is checked in the View Menu
- Use Rectangular Marquee tool to select the 1/2” strip between the guides along one of the edges
- Click Edit ⇨ Transform ⇨ Scale
- Place the mouse cursor over the little square in the middle of the outer edge of the selected area and drag to the edge of the canvas
- Hit the check mark to finish the transform
- Repeat Steps 2 through 5 with the 1/2” strips along the other three edges
Then I add a blank (transparent) edge around the image representing the canvas I need for stretching the canvas around the frame by increasing the canvas size by double the required margins in both dimensions, the same way we did above. That margin would be at least the width of the moulding along the bottom (1″ for the 11/2” moulding we are using now) and enough extra to get a grip with the canvas pliers (for me that’s at least 3/4“). That would make the image’s final dimensions at least 191/2” x 251/2“. When I am finished, I add layers with cut lines, fold lines, staple lines, positioning marks for the hanging hardware, etcetera, but that is a personal matter beyond the scope of this article.
That’s about it. Feel free to leave comments or questions.
