I did a search on-line:
Which paper works best with ProMarkers?
Letraset Bleedproof Paper is widely regarded as the best to use - although lightweight at just 70gsm, it has been specially formulated to prevent marker ink from bleeding. It's also very white and smooth and will make you colours look rich and vibrant with high levels of contrast. If you're not using Bleedproof Marker Paper, you should use a heavyweight paper or card stock with a smooth coated surface.
Applying ProMarkers to other surfaces
ProMarkers are permanent and can be applied to a wide variety of different surfaces. If you're layering ProMarker onto an ink resistant surface like acetate of glass, this should be done gradually to let the colour dry between coats. If applying ProMarker to a textured or porous surface like bare wood or textile, the ink will bleed outwards slightly so make allowance for this when working close to the edges.
