Most any paper media will cut about the same when coated with either the Hahnemuhle or Premier Art Print Shield Sprays, both of which a essentially the same thing and produce very hard and scratch resistant surfaces on most gloss media, and slightly weaker and slightly scuff-prone surfaces on matte media. Both those sprays produce nasty smells that dissipate quickly but still require the use of a mask with an organic filter in a place with good ventilation. By comparison most Home Depot sprays and thing like Krylon UV resistant sprays for art produce far nastier smells that take hours to dissipate from the print surface. Some canvas-coating sprayed surfaces may shatter slightly when cut, producing a kind of ragged looking edge, so experimentation is needed with those.
Cutting mounted print packages should be done with a sharp blade and a good, steel straight edge. For best results, gently clamp the cutting edge. For the cleanest cuts, utility knife blade should be held to very slightly face in toward the cutting edge, and held relentlessly at the angle for about 4 or more gentle swipes. That blade angle will position most of the inevitable burr on the piece that is being discarded, and leave the cleanest edge on the substrate. The print is the hardest part to cut through, if you are using Gator or fomecore. Sometimes it is helpful to first make a rough cut to within about 1/4 inch of the desired final cut, then fine trim that 1/4 inch piece away with super gentle cuts, which will produce the minimum burr on the print edge and arguably mangle the exposed foam sides the least. Use the chrome-like smooth shaft of a screwdriver to burnish down the burr on the print. It's best to cut within, say, 1/2 day of spraying before the sprayed surface is 100% hardened, the burr is easier to squash down at that point. With the fast drying Hahn/Premier sprays you can mount and cut very soon after coating, almost as soon as the smell dissipates.
Nobody is cool until they own one of these
cutting edges. The foam padded base can be safely placed right over the print, and contrary to what the ad says the vertical bar is a great place to press down with the hand not doing the cutting. The weight and the foam pads keep the edge from moving during a cut and those big flat areas are good targets for 8 inch
Irwin clamps for use during those heavy and long cuts. I have 64 and 100 inch versions of the cutter. The 64 can be used for even tiny prints if I balance the "32" mark right over the print. There are both lesser and better grades available in many sizes.
Mount a scrap print on your substrate of choice and spend an hour whittling away. Much will be learned and it's good therapy.
EDIT:
these hangers are OK for pieces weighing less than about 300 grams, anything heavier and you are cruising for a bruising. Do not use with picture frames, please!
