Are you using home printed glossy paper? I always use high quality matte prints that i get done online and ive never had a sig smudge, even the silver ones.
Great success

Im in the UK so i use the Boots Photo website, but if you're in the US try Snapfish. They're actually the same company, and i used to use SF until they put their international postage costs up, so I switched over to Boots Photo service. I prefer matte to glossy anyway. If you frame or display your autographs you wont get as much irritating glare from lights on them
