These instructions are for stretching inkjet prints on canvas that can be easily reproduced - not originals, limited editions or paintings with financial or sentimental value. Browse our website and read our current trade catalogue for details of our wide range of specialist materials, accessories, equipment and tools that will speed up and give consistency to the task. For a demonstration, come and see us in Birmingham.
Use a table top corner as a guide, and a rubber mallet.
If bracing is desired for a larger size, attach the brace/s in the brace slots, for later tensioning.
7. Move to a side and follow the same procedure, pulling firmly and stapling canvas to the stretcher at the centre, create first a triangle crease and then a diamond crease in the canvas with the fourth staple, at the opposite long side.

2. Alternatively, you can buy some stretcher bar profiles in long lengths. You cut and join these as you would any frame moulding. This can be very convenient for unusual sizes. The only drawback is that you cannot use wedges later for re-tensioning the canvas.

Stretching Fine Art Canvases PUB 005
Paintings or prints on canvas are traditionally framed after being stretched. Gallery Wrap is a style of stretching canvases onto deep sided stretchers, with the artwork continuing over the edge of the stretcher, remaining visible on the sides. The canvas is stapled on the back and neatly finished on the sides and corners, so that framing is not necessary. Framed or not, the canvas surface is left uncovered so that light falls directly on the image, undistorted by the reflective qualities of plastic or glass. Delicate printed images can be protected with heatseal film before stretching or varnished
after stretching. See print lacquers in current Lion trade catalogue.

There are four basic stages to stretching an inkjet printed canvas:
- Preparing the canvas
- Assembling stretcher bars
- Stretching the canvas
- Finishing the job

Depending on the equipment you have available and the type of work you do the laminate protection can be a hot over- laminate, applied with a heated press.
B Assembling stretcher bars
Slot the bars together loosely by hand and use a soft faced hammer to knock them fully together.
Check the frame is square by measuring
Stretcher bars have special jointed corners that allow them to be slotted together. Wooden wedges are supplied with Lion stretcher bars. Over time, if the canvas sags, the wedges can be tapped further into the joints, opening them slightly and re-tensioning the canvas.
the distance between opposite corners. If you are assembling stretcher bars on a regular basis a 90° angle jig on your workbench will save time.
Stretcher bars are supplied in pairs. For a frame that is 406mm x 508mm / 16” x 20” you would order one pair of 406mm and one pair of 508mm bars. See current Lion Trade catalogue.
On larger frames, single or cross braces can be used with Premium or Gallery stretcher bar profiles.
