Canvas profiling uses the same basic printer-profiling process as paper. You print a target chart on the canvas, then measure the patches with a printer-profiling device to build an ICC profile.

So you generally need printer-profiling hardware/software rather than a special “canvas-only” calibrator. One community answer notes that the same process applies as with any printer media. Another reports that X-Rite recommended the i1Publish Pro 2 for this kind of work.

In practice, the key is that the device must support printer profiling by reading printed color patches; monitor-only calibrators are not enough. Also, because canvas has its own texture and surface characteristics, profiling that specific canvas/printer/ink combination is important for best accuracy.
