I believe that the Exhibition Satin is just like the glossy, i.e. it is designed for a PK black. Only a matte canvas is really going to work well with a matte black. So the PK ink setting should be the correct one. Does Epson call for matte ink on the satin canvas? I have never used the Epson satin, but all the other brands I have used ask for a Photo ink on satin canvas.
Depending on your printer, if Epson, there will be a profile (icc) for this canvas, and a Media setting (more than likely Premium Luster Paper) as this is what Epson uses on most glossy or satin canvas.
You can print with PK on matte easier than going with matte on a canvas with a glossy/satin coating.
